Gets the wrapped object.

Overrides:

getWrapped in class RenderStateWrapper

Returns:

the wrapped object.

setWrapped

public void setWrapped(BaseURL wrapped)

Sets the wrapped object.

Parameters:

wrapped - the wrapped object to set.

setParameter

@Deprecated
public void setParameter(String name,
                                     String value)

Deprecated.

Description copied from interface: BaseURL

Sets the given String parameter on this URL.

This method replaces all parameter values with the given key, as allowed according to the rules for the URL.

• RenderURL - Both public and private parameters can be set.
• ActionURL - Action parameters (private parameters) are set as described. Public render parameters remain unchanged. If an action parameter has the same name as a public render parameter, both the action parameter value and the public render parameter value will be available during processing of the action request.
• ResourceURL - Resource parameters are set. Public and private render parameters that were attached to the URL when it was created remain unchanged. If a resource parameter has the same name as a public or private render parameter, both the resource parameter value and the public or private render parameter value will be available during processing of the resource request.

The PortletURL implementation 'x-www-form-urlencoded' encodes all parameter names and values. Developers should not encode them.

A portlet container may prefix the attribute names internally in order to preserve a unique namespace for the portlet.

A parameter value of null indicates that this parameter should be removed. However, an empty string value ("") is allowed.

A public render parameter cannot be removed by setting its value to null.

Specified by:

setParameter in interface BaseURL

Parameters:

name - the parameter name

value - the parameter value

setParameter

@Deprecated
public void setParameter(String name,
                                     String... values)

Deprecated.

Description copied from interface: BaseURL

Sets a multi-valued String parameter on this URL.

This method replaces all parameter values with the given key according to the rules for the URL.

• RenderURL - Both public and private parameters can be set.
• ActionURL - Action parameters (private parameters) are set as described. Public render parameters remain unchanged. If an action parameter has the same name as a public render parameter, both the action parameter value and the public render parameter value will be available during processing of the action request.
• ResourceURL - Resource parameters are set. Public and private render parameters that were attached to the URL when it was created remain unchanged. If a resource parameter has the same name as a public or private render parameter, both the resource parameter value and the public or private render parameter value will be available during processing of the resource request.

The PortletURL implementation 'x-www-form-urlencoded' encodes all parameter names and values. Developers should not encode them.

A portlet container may prefix the attribute names internally in order to preserve a unique namespace for the portlet.

A values parameter of null indicates that this parameter should be removed.

If the values parameter is not null, no element of the values array may be null. However, an empty string value ("") is allowed.

Specified by:

setParameter in interface BaseURL

Parameters:

name - the parameter name

values - the parameter values

setParameters

@Deprecated
public void setParameters(Map<String,String[]> parameters)

Deprecated.

Description copied from interface: BaseURL

Sets a parameter map for this URL.

All previously set parameters are cleared.

This method can be used to set both public and private render parameters according to the rules for the URL.

• RenderURL - Both public and private parameters can be set.
• ActionURL - Action parameters are set. Public render parameters remain unchanged. If an action parameter has the same name as a public render parameter, both the action parameter value and the public render parameter value will be available during processing of the action request.
• ResourceURL - Resource parameters are set. Public and private render parameters that were attached to the URL when it was created remain unchanged. If a resource parameter has the same name as a public or private render parameter, both the resource parameter value and the public or private render parameter value will be available during processing of the resource request.

These parameters will be accessible through the portlet request initiated through the URL.

Any previously set private render parameter that is not contained in the new map is removed. However, public render parameters cannot be removed by excluding them from the map. Public render parameters that are not included in the map remain unchanged.

The PortletURL implementation 'x-www-form-urlencoded' encodes all parameter names and values. Developers should not encode them.

A portlet container may prefix the attribute names internally, in order to preserve a unique namespace for the portlet.

Specified by:

setParameters in interface BaseURL

Parameters:

parameters - Map containing parameter names for the render phase as keys and parameter values as map values. The keys in the parameter map must be of type String and may not be null or the empty string (""). The values in the parameter map must be of type String array (String[]). Neither the values array nor any of its elements may be null; however, the empty string ("") is allowed as an array element.

setSecure

public void setSecure(boolean secure)
               throws PortletSecurityException

Description copied from interface: BaseURL

Indicates the security setting for this URL.

Secure set to true indicates that the portlet requests a secure connection between the client and the portlet window for this URL. Secure set to false indicates that the portlet does not need a secure connection for this URL. If the security is not set for a URL, it should stay the same as the current request.

Specified by:

setSecure in interface BaseURL

Parameters:

secure - true, if portlet requests to have a secure connection between its portlet window and the client; false, if the portlet does not require a secure connection.

Throws:

PortletSecurityException - if the run-time environment does not support the indicated setting

getParameterMap

@Deprecated
public Map<String,String[]> getParameterMap()

Deprecated.

Description copied from interface: BaseURL

Returns a Map of the parameters currently set on this portlet URL.

The values in the returned Map are from type String array (String[]).

The contents of the returned map are immutable in the sense that modifying the map does not directly affect the render parameters. In order to set the parameters using the modified map, the BaseURL.setParameters(Map) method must be used.

If no parameters exist this method returns an empty Map.

Specified by:

getParameterMap in interface BaseURL

Returns:

Map containing parameter names as keys and parameter values as map values, or an empty Map if no parameters exist. The keys in the parameter map are of type String. The values in the parameter map are of type String array (String[]).

write

public void write(Writer out)
           throws IOException

Description copied from interface: BaseURL

Writes the portlet URL to the output stream using the provided writer.

Note that the URL written to the output stream may not be a valid URL, as it may be rewritten by the portal/portlet-container before returning the markup to the client.

The URL written to the output stream is always XML escaped. For writing non-escaped URLs use BaseURL.write(java.io.Writer, boolean).

Specified by:

write in interface BaseURL

Parameters:

out - the writer to write the portlet URL to

Throws:

IOException - if an I/O error occurred while writing the URL

write

public void write(Writer out,
                  boolean escapeXML)
           throws IOException

Description copied from interface: BaseURL

Writes the portlet URL to the output stream using the provided writer. If the parameter escapeXML is set to true the URL will be escaped to be valid XML characters, i.e. <, >, &, ', " will get converted into their corresponding character entity codes (< to &<, > to &>, & to &&, ' to &', " to &"). If escapeXML is set to false no escaping will be done. The manner in which escaping is performed is implementation specific. If escapeXML is set to false, escaping the URL is left to the implementation.

Note that the URL written to the output stream may not be a valid URL, as it may be rewritten by the portal/portlet-container before returning the markup to the client.

Specified by:

write in interface BaseURL

Parameters:

out - the writer to write the portlet URL to

escapeXML - denotes if the URL should be XML escaped before written to the output stream or not

Throws:

IOException - if an I/O error occurred while writing the URL

append

public Appendable append(Appendable out)
                  throws IOException

Description copied from interface: BaseURL

Appends the portlet URL to the appendable object.

Note that the appended URL may not be a valid URL, as it may be rewritten by the portal/portlet-container before returning the markup to the client.

The appended URL is always XML escaped. For appending non-escaped URLs use BaseURL.append(java.lang.Appendable, boolean).

Specified by:

append in interface BaseURL

Parameters:

out - the object to receive the URL

Returns:

Appendable the Appendable object containing the URL

Throws:

IOException - if an I/O error occurred while writing the URL

append

public Appendable append(Appendable out,
                         boolean escapeXML)
                  throws IOException

Description copied from interface: BaseURL

Appends the portlet URL to the appendable object.

If the parameter escapeXML is set to true, the URL will be escaped to be valid XML characters. The manner in which escaping is performed is implementation specific. If escapeXML is set to false, escaping the URL is left to the implementation.

Note that the appended URL may not be a valid URL, as it may be rewritten by the portal/portlet-container before returning the markup to the client.

Specified by:

append in interface BaseURL

Parameters:

out - the object to receive the URL

Returns:

Appendable the Appendable object containing the URL

Throws:

IOException - if an I/O error occurred while writing the URL

addProperty

public void addProperty(String key,
                        String value)

Description copied from interface: BaseURL

Adds a String property to an existing key on the URL.

This method allows URL properties to have multiple values.

Properties can be used by portlets to provide vendor specific information to the URL.

Specified by:

addProperty in interface BaseURL

Parameters:

key - the key of the property

value - the value of the property

setProperty

public void setProperty(String key,
                        String value)

Properties can be used by portlets to provide vendor specific information to the URL.

This method resets all properties previously added with the same key.

Specified by:

setProperty in interface BaseURL

Parameters:

key - the key of the property

value - the value of the property

toString

public String toString()

Description copied from interface: BaseURL

Returns the portlet URL string representation to be embedded in the markup.
Note that the returned String may not be a valid URL, as it may be rewritten by the portal/portlet-container before returning the markup to the client.

The returned URL is not XML escaped.

For writing URLs to an output stream the BaseURL.write(java.io.Writer) or BaseURL.write(java.io.Writer, boolean) method should be used as these are more efficient.

Specified by:

toString in interface BaseURL

Overrides:

toString in class Object

Returns:

the encoded URL as a string
