ReferenceNode

static class ReferenceNode.PlainReferenceNode
extends ReferenceNode

A node in the parse tree that is a plain reference such as $x. This node may appear inside a more complex reference like $x.foo.

Method Details

evaluate

Object evaluate(EvaluationContext context)

Description copied from class: Node

Returns the result of evaluating this node in the given context. This result may be used as part of a further operation, for example evaluating 2 + 3 to 5 in order to set $x to 5 in #set ($x = 2 + 3). Or it may be used directly as part of the template output, for example evaluating replacing name by Fred in My name is $name..

Specified by:

evaluate in class Node

isDefinedAndTrue

boolean isDefinedAndTrue(EvaluationContext context)

Description copied from class: ExpressionNode

True if this is a defined value and it evaluates to true. This is the same as ExpressionNode.isTrue(EvaluationContext) except that it is allowed for this to be undefined variable, in which it evaluates to false. The method is overridden for plain references so that undefined is the same as false. The reason is to support Velocity's idiom #if ($var), where it is not an error if $var is undefined.

Overrides:
