public class BodyPresentationContext

extends PresentationContext

This class represents a portal body component. All presentation-related attributes of a body component are available from instances of this class. Such instances are typically used during portal rendering via look and feel skeleton files (e.g. body.jsp).

Method Detail

getOnloadScript

public String getOnloadScript()

Returns any configured onload script code that should appear in an HTML/XHTML body's onload attribute. This information is the aggregation of code generated by components of the portal runtime and/or configured in the look and feel's .skin, .skeleton, and/or skin.properties file. This is a convenience method that can be used instead of getEventHandlerScript(String) with the argument "onload".

Returns

A string containing the aggregated script code to be executed after the body element has loaded into the consuming client (typically an HTML/XHTML browser supporting JavaScript or another client-side scripting language); this will return an empty string if no statements are configured for the onload event handler

getOnunloadScript

public String getOnunloadScript()

Returns any configured 'onunload' script code that should appear in an HTML/XHTML body's 'onunload' attribute. This information is the aggregation of code generated by components of the portal runtime and/or configured in the look and feel's .skin, .skeleton, and/or skin.properties file. This is a convenience method that can be used instead of getEventHandlerScript(String) with the argument "onunload".

Returns

A string containing the aggregated script code to be executed after the body element has unloaded from the consuming client (typically an HTML/XHTML browser supporting JavaScript or another client-side scripting language); this will return an empty string if no statements are configured for the onunload event handler

getPopulatedEventHandlerNames

public Set<String> getPopulatedEventHandlerNames()

Returns the names of any HTML/XHTML body tag event handlers that have had script statements added to them in the look and feel's configuration files (i.e. .skin, .skeleton, and/or skin.properties files). Each of the named event handlers in the resulting list will have a non-trivial script (obtained with getEventHandlerScript(String)), and therefore 1-n associated script fragments (obtained with getEventHandlerStatements(String)).

Returns

A list of strings containing the names of all body event handler names with non-trivial scripts associated with them

getEventHandlerStatements

public List<String> getEventHandlerStatements(String eventHandlerName)

Returns a list of script statements configured for this body element as specified in the look and feel's .skin, .skeleton, and/or skin.properties files.

Parameters

eventHandlerName - The name of the event handler for which to fetch the list of statements; if the name specified is returned by getPopulatedEventHandlerNames(), then this list will contain at least one associated statement

Returns

The list of statements for the named event handler or an empty list if no statements are configured for that event handler

getPopulatedEventHandlerNames()

getEventHandlerScript

public String getEventHandlerScript(String eventHandlerName)

Returns any configured script code that should appear in an HTML/XHTML body's event handler attribute for the named event handler. This information is the aggregation of code generated by components of the portal runtime and/or configured in the look and feel's .skin, .skeleton, and/or skin.properties file.

Returns

A string containing the aggregated script code to be executed after the body element has loaded into the consuming client (typically an HTML/XHTML browser supporting JavaScript or another client-side scripting language) or an empty string if no statements are configured for the named event handler

getAttributeRenderer

public BodyAttributeRenderer getAttributeRenderer()

Returns a renderer for body's attributes. This renderer is intended to be used in skeleton files.

Overrides:

getAttributeRenderer in class PresentationContext

getBodyPresentationContext

public static BodyPresentationContext getBodyPresentationContext(javax.servlet.http.HttpServletRequest request)

This is a convenience method for returning a reference to the one and only BodyPresentationContext. Note this method will only work if called from within a portal (typically, from the body.jsp skeleton). This method may return null if called when no appropriate context exists, but such a context should safely exist when being fetched from the associated skeleton JSP during normal portal rendering.

Parameters

request - The current HTTPServletRequest instance

Returns

A reference to the current BodyPresentationContext, if any
