Method Summary

Modifier and Type	Method	Description
<R, P> R	accept(NodeVisitor<? extends R,? super P> visitor, P data)	Supports the Visitor pattern.
protected Object	getValueBody(OgnlContext context, Object source)	Subclasses implement this method to do the actual work of extracting the appropriate value from the source object.
protected void	setValueBody(OgnlContext context, Object target, Object value)	Subclasses implement this method to do the actual work of setting the appropriate value in the target object.
String	toGetSourceString(OgnlContext context, Object target)	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.
String	toSetSourceString(OgnlContext context, Object target)	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.

Method Details

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
