Modifier and Type

Method

Description

String

getCoreExpression()

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

Class

getGetterClass()

The type returned from the expression - if any.

String

getLastExpression()

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

String

getMethodName()

Returns the method name that this node will call.

Class

getSetterClass()

The type used to set the value - if any.

protected Object

getValueBody(OgnlContext context, Object source)

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

void

setMethodName(String methodName)

Called from parser action.

String

toGetSourceString(OgnlContext context, 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.

String

toSetSourceString(OgnlContext context, 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.
