Methods

Modifier and Type	Method and Description
java.lang.String	getCoreExpression() Get the core expression to execute first before any return foo logic is started.
java.lang.Class	getGetterClass() The type returned from the expression - if any.
java.lang.String	getLastExpression() Gets the last expression to be pre-pended with a return <expression> block.
java.lang.String	getMethodName() Returns the method name that this node will call.
java.lang.Class	getSetterClass() The type used to set the value - if any.
protected java.lang.Object	getValueBody(OgnlContext context, java.lang.Object source) Subclasses implement this method to do the actual work of extracting the appropriate value from the source object.
boolean	isSimpleMethod(OgnlContext context)
void	setMethodName(java.lang.String methodName) Called from parser action.
java.lang.String	toGetSourceString(OgnlContext context, java.lang.Object target) Expected to return a java source representation of itself such that it could be turned into a literal java expression to be compiled and executed for ExpressionAccessor.get(OgnlContext, Object) calls.
java.lang.String	toSetSourceString(OgnlContext context, java.lang.Object target) Expected to return a java source representation of itself such that it could be turned into a literal java expression to be compiled and executed for ExpressionAccessor.get(OgnlContext, Object) calls.
java.lang.String	toString()
