All Implemented Interfaces:

ActionDelegate, NavBarActionDelegate

Direct Known Subclasses:

ThumbnailURLActionDelegate

public class ThumbnailActionDelegate

extends Object

implements NavBarActionDelegate

Field Summary

private String	action
static String	CONTEXT_SERVICE_NAME
private HTTPState	state

Constructor Summary

ThumbnailActionDelegate()

Method Summary

Boolean	enableable(Object object) Tests if the action is currently applicable to the instance object; commonly used at the time a GUI is generated to see if the action should be "enabled" for the object, another common usage will be at the time that the action is to be performed, to see if it is still applicable.
String	getContextServiceName() This method is to allow access to the variable, CONTEXT_SERVICE_NAME.
HTTPState	getState()
void	setActionName(String action) Sets the current Action.
void	setState(HTTPState state) Sets the current HTTPState from the TemplateProcessor that is being used to generate the Navigation Bar.
Boolean	valid(Object object) Tests if the action is valid on all instances of the class of object; commonly used in the construction of dynamically generated GUIs to determine if a particular action should appear.

Method Detail

setState

public void setState(HTTPState state)

Sets the current HTTPState from the TemplateProcessor that is being used to generate the Navigation Bar.

Supported API: false

Specified by:

setState in interface NavBarActionDelegate

Parameters:

state - The current HTTPState.

Returns:

void

getState

public HTTPState getState()

setActionName

public void setActionName(String action)

Sets the current Action. This is a bit of a kludge to allow re-using existing ActionDelegates

Supported API: false

Specified by:

setActionName in interface NavBarActionDelegate

Parameters:

action -

Returns:

void

valid

public Boolean valid(Object object)

Tests if the action is valid on all instances of the class of object; commonly used in the construction of dynamically generated GUIs to determine if a particular action should appear. For instance, the valid method of the "check-in" action will test if the object is "Workable" or not.

Supported API: false

Specified by:

valid in interface ActionDelegate

Parameters:

object - The object that you want to test validity on.

Returns:

Boolean

enableable

public Boolean enableable(Object object)
                   throws WTException

Tests if the action is currently applicable to the instance object; commonly used at the time a GUI is generated to see if the action should be "enabled" for the object, another common usage will be at the time that the action is to be performed, to see if it is still applicable. This method should not be called when the concrete ActionDelegate class is unknown. In that case, call BasicTemplateProcessor.accessOK() instead.

Supported API: false

Specified by:

enableable in interface ActionDelegate

Parameters:

object - The object that you wish to set enabled.

Returns:

Boolean

Throws:

WTException

getContextServiceName

public String getContextServiceName()

This method is to allow access to the variable, CONTEXT_SERVICE_NAME. The role of the variable CONTEXT_SERVICE_NAME is to provide a reference name of the Action being performed. The value of CONTEXT_SERVICE_NAME should be set in the subclass that implements this interface.

Supported API: false

Specified by:

getContextServiceName in interface ActionDelegate

Returns:

String
