Method Detail

getValueBody

protected java.lang.Object getValueBody(OgnlContext context,
                                        java.lang.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 class ASTVarRef
Throws:
OgnlException

setValueBody

protected void setValueBody(OgnlContext context,
                            java.lang.Object target,
                            java.lang.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 an InappropriateExpressionException, meaning that it cannot be a set expression.

Overrides:
setValueBody in class ASTVarRef
Throws:
OgnlException

toString

public java.lang.String toString()
Overrides:
toString in class ASTVarRef

toGetSourceString

public java.lang.String toGetSourceString(OgnlContext context,
                                          java.lang.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 for ExpressionAccessor.get(OgnlContext, Object) calls.

Specified by:
toGetSourceString in interface JavaSource
Overrides:
toGetSourceString in class ASTVarRef
Returns:
Literal java string representation of an object get.

toSetSourceString

public java.lang.String toSetSourceString(OgnlContext context,
                                          java.lang.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 for ExpressionAccessor.get(OgnlContext, Object) calls.

Specified by:
toSetSourceString in interface JavaSource
Overrides:
toSetSourceString in class ASTVarRef
Returns:
Literal java string representation of an object get.
