Method Detail

setMethodName

public void setMethodName(java.lang.String methodName)

Called from parser action.

Parameters:

methodName - the method name.

getMethodName

public java.lang.String getMethodName()

Returns the method name that this node will call.

Returns:

the method name.

getValueBody

protected java.lang.Object getValueBody(OgnlContext context,
                                        java.lang.Object source)
                                 throws OgnlException

Description copied from class: SimpleNode

Subclasses implement this method to do the actual work of extracting the appropriate value from the source object.

Specified by:

getValueBody in class SimpleNode

Parameters:

context - the OgnlContext within which to perform the operation.

source - the Object from which to get the value body.

Returns:

the value body from the source (as appropriate within the provided context).

Throws:

OgnlException - if the value body get fails.

getLastExpression

public java.lang.String getLastExpression()

Description copied from interface: OrderedReturn

Gets the last expression to be pre-pended with a return <expression> block.

Specified by:

getLastExpression in interface OrderedReturn

Returns:

The expression representing the return portion of a statement;

getCoreExpression

public java.lang.String getCoreExpression()

Description copied from interface: OrderedReturn

Get the core expression to execute first before any return foo logic is started.

Specified by:

getCoreExpression in interface OrderedReturn

Returns:

The core standalone expression that shouldn't be pre-pended with a return keyword.

getGetterClass

public java.lang.Class<?> getGetterClass()

Description copied from interface: NodeType

The type returned from the expression - if any.

Specified by:

getGetterClass in interface NodeType

Returns:

The type.
