Uses of Node in ognl.enhance

Methods in ognl.enhance with parameters of type Node

Modifier and Type	Method and Description
String	OgnlExpressionCompiler.castExpression(OgnlContext context, Node expression, String body) Used primarily by AST types like ASTChain where foo.bar.id type references may need to be cast multiple times in order to properly resolve the members in a compiled statement.
String	ExpressionCompiler.castExpression(OgnlContext context, Node expression, String body)
void	OgnlExpressionCompiler.compileExpression(OgnlContext context, Node expression, Object root) The core method executed to compile a specific expression.
void	ExpressionCompiler.compileExpression(OgnlContext context, Node expression, Object root)
protected String	ExpressionCompiler.generateGetter(OgnlContext context, javassist.CtClass newClass, javassist.CtClass objClass, javassist.ClassPool pool, javassist.CtMethod valueGetter, Node expression, Object root)
protected String	ExpressionCompiler.generateSetter(OgnlContext context, javassist.CtClass newClass, javassist.CtClass objClass, javassist.ClassPool pool, javassist.CtMethod valueSetter, Node expression, Object root)
static String	ExpressionCompiler.getRootExpression(Node expression, Object root, OgnlContext context) Convenience method called by many different property/method resolving AST types to get a root expression resolving string for the given node.
Class	OgnlExpressionCompiler.getRootExpressionClass(Node rootNode, OgnlContext context) For a given root object type returns the base class type to be used in root referenced expressions.
Class	ExpressionCompiler.getRootExpressionClass(Node rootNode, OgnlContext context)
void	ExpressionAccessor.setExpression(Node expression) Used to set the original root expression node on instances where the compiled version has to fall back to interpreted syntax because of compilation failures.
static boolean	ExpressionCompiler.shouldCast(Node expression) Used by ExpressionCompiler.getRootExpression(ognl.Node, Object, ognl.OgnlContext) to determine if the expression needs to be cast at all.
