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 class ASTVarRef

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 an InappropriateExpressionException, meaning that it cannot be a set expression.

Overrides:

setValueBody in class ASTVarRef

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 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 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 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.

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 interface Node

Overrides:

accept in class ASTVarRef

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
