getValueBody
protected Object getValueBody(OgnlContext context, 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.- Overrides:
getValueBody
in classASTVarRef
- Throws:
OgnlException
-
setValueBody
protected void setValueBody(OgnlContext context, Object target, Object value) throws OgnlException
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 classASTVarRef
- Throws:
OgnlException
-
toGetSourceString
public String toGetSourceString(OgnlContext context, Object target)
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 classASTVarRef
- Returns:
- Literal java string representation of an object get.
-
toSetSourceString
public String toSetSourceString(OgnlContext context, Object target)
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:
toSetSourceString
in interfaceJavaSource
- Overrides:
toSetSourceString
in classASTVarRef
- Returns:
- Literal java string representation of an object get.
-
accept
public <R,P> R accept(NodeVisitor<? extends R,? super P> visitor, P data) throws OgnlException
Description copied from interface:Node
Supports the Visitor pattern. The method which corresponds to the runtime type of this Node will be called.- Specified by:
accept
in interfaceNode
- Overrides:
accept
in classASTVarRef
- Type Parameters:
R
- The return type of the visitor.visit method.P
- 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:
OgnlException
