| HandlerProxy | | final public class HandlerProxy extends AbstractHandler implements IElementUpdater(Code) | |
A proxy for a handler that has been defined in XML. This delays the class
loading until the handler is really asked for information (besides the
priority or the command identifier). Asking a proxy for anything but the
attributes defined publicly in this class will cause the proxy to instantiate
the proxied handler.

| Constructor Summary | |
| public | HandlerProxy(IConfigurationElement configurationElement, String handlerAttributeName)
Constructs a new instance of HandlerProxy with all the
information it needs to try to avoid loading until it is needed. | | public | HandlerProxy(IConfigurationElement configurationElement, String handlerAttributeName, Expression enabledWhenExpression, IEvaluationService evaluationService)
Constructs a new instance of HandlerProxy with all the
information it needs to try to avoid loading until it is needed.
Parameters:
configurationElement - The configuration element from which the real class can beloaded at run-time; must not be null.
Parameters:
handlerAttributeName - The name of the attribute or element containing the handlerexecutable extension; must not be null.
Parameters:
enabledWhenExpression - The name of the element containing the enabledWhen expression.This should be a child of theconfigurationElement. |
| HandlerProxy | | public HandlerProxy(IConfigurationElement configurationElement, String handlerAttributeName)(Code) | | Constructs a new instance of HandlerProxy with all the
information it needs to try to avoid loading until it is needed.
Parameters:
configurationElement - The configuration element from which the real class can beloaded at run-time; must not be null.
Parameters:
handlerAttributeName - The name of the attibute or element containing the handlerexecutable extension; must not be null. |
| HandlerProxy | | public HandlerProxy(IConfigurationElement configurationElement, String handlerAttributeName, Expression enabledWhenExpression, IEvaluationService evaluationService)(Code) | | Constructs a new instance of HandlerProxy with all the
information it needs to try to avoid loading until it is needed.
Parameters:
configurationElement - The configuration element from which the real class can beloaded at run-time; must not be null.
Parameters:
handlerAttributeName - The name of the attribute or element containing the handlerexecutable extension; must not be null.
Parameters:
enabledWhenExpression - The name of the element containing the enabledWhen expression.This should be a child of theconfigurationElement. If this value isnull, then there is no enablement expression(i.e., enablement will be delegated to the handler whenpossible).
Parameters:
evaluationService - The evaluation service to manage enabledWhen expressionstrying to evaluate the enabledWhenExpression.This value may be null only if theenabledWhenExpression is null. |
