getValueBody
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 classSimpleNode
- Throws:
OgnlException
-
setValueBody
Description copied from class:SimpleNode
Subclasses implement this method to do the actual work of setting the appropriate value in the target object. The default implementation throws anInappropriateExpressionException
, meaning that it cannot be a set expression.- Overrides:
setValueBody
in classSimpleNode
- Throws:
OgnlException
-
getGetterClass
Description copied from interface:NodeType
The type returned from the expression - if any.- Specified by:
getGetterClass
in interfaceNodeType
- Returns:
- The type.
-
getSetterClass
Description copied from interface:NodeType
The type used to set the value - if any.- Specified by:
getSetterClass
in interfaceNodeType
- Returns:
- The type.
-
getCoreExpression
Description copied from interface:OrderedReturn
Get the core expression to execute first before any return foo logic is started.- Specified by:
getCoreExpression
in interfaceOrderedReturn
- Returns:
- The core standalone expression that shouldn't be pre-pended with a return keyword.
-
getLastExpression
Description copied from interface:OrderedReturn
Gets the last expression to be pre-pended with a return <expression> block.- Specified by:
getLastExpression
in interfaceOrderedReturn
- Returns:
- The expression representing the return portion of a statement;
-
toString
- Overrides:
toString
in classSimpleNode
-

- Overrides:
toGetSourceString
in classSimpleNode
- Returns:
- Literal java string representation of an object get.
-
toSetSourceString
Description copied from interface:JavaSource
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 forExpressionAccessor.get(OgnlContext, Object)
calls.- Specified by:
