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
-
getExpressionOperator
- Overrides:
getExpressionOperator
in classExpressionNode
-
toGetSourceString
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:
toGetSourceString
in interfaceJavaSource
- Overrides:
toGetSourceString
in classExpressionNode
- Returns:
- Literal java string representation of an object get.
-
accept

- The type of the second parameter type.- Parameters:
visitor
- The visitor to accept.data
- The second parameter to pass through to visitor.visit- Returns:
- the value returned by visitor.visit
- Throws:
