Method Detail

getMethodInfo

public javax.el.MethodInfo getMethodInfo(javax.el.ELContext context)
                                  throws javax.el.ELException

Specified by:

getMethodInfo in class javax.el.MethodExpression

Throws:

javax.el.ELException

invoke

public Object invoke(javax.el.ELContext context,
                     Object[] params)
              throws javax.el.ELException

Specified by:

invoke in class javax.el.MethodExpression

Throws:

javax.el.ELException

getExpressionString

public String getExpressionString()

Specified by:

getExpressionString in class javax.el.Expression

isLiteralText

public boolean isLiteralText()

Specified by:

isLiteralText in class javax.el.Expression

equals

public boolean equals(Object other)

Specified by:

equals in class javax.el.Expression

hashCode

public int hashCode()

Specified by:

hashCode in class javax.el.Expression

getDelimiterSyntax

public String getDelimiterSyntax()

saveState

public Object saveState(FacesContext context)

Description copied from interface: StateHolder

Gets the state of the instance as a Serializable Object.

If the class that implements this interface has references to instances that implement StateHolder (such as a UIComponent with event handlers, validators, etc.) this method must call the StateHolder.saveState(javax.faces.context.FacesContext) method on all those instances as well. This method must not save the state of children and facets. That is done via the StateManager

This method must not alter the state of the implementing object. In other words, after executing this code:

 Object state = component.saveState(facesContext);
 

component should be the same as before executing it.

The return from this method must be Serializable

Specified by:

saveState in interface StateHolder

Parameters:

context - the Faces context.

Returns:

the saved state.

restoreState

public void restoreState(FacesContext context,
                         Object state)

Description copied from interface: StateHolder

Perform any processing required to restore the state from the entries in the state Object.

If the class that implements this interface has references to instances that also implement StateHolder (such as a UIComponent with event handlers, validators, etc.) this method must call the StateHolder.restoreState(javax.faces.context.FacesContext, java.lang.Object) method on all those instances as well.

If the state argument is null, take no action and return.

Specified by:

restoreState in interface StateHolder

Parameters:

context - the Faces context.

state - the state.

isTransient

public boolean isTransient()

Description copied from interface: StateHolder

If true, the Object implementing this interface must not participate in state saving or restoring.

Specified by:

isTransient in interface StateHolder

Returns:

true if transient, false otherwise.

setTransient

public void setTransient(boolean newTransientMethod)

Description copied from interface: StateHolder

Denotes whether or not the Object implementing this interface must or must not participate in state saving or restoring.

Specified by:

setTransient in interface StateHolder

Parameters:

newTransientMethod - boolean pass true if this Object will not participate in state saving or restoring, otherwise pass false.

getWrapped

public MethodBinding getWrapped()
