static class DirectiveNode.IfNode extends DirectiveNode
A node in the parse tree representing an#if
construct. All instances of this class have a true subtree and a false subtree. For a plain#if (cond) body #end
, the false subtree will be empty. For#if (cond1) body1 #elseif (cond2) body2 #else body3 #end
, the false subtree will contain a nestedIfNode
, as if#else #if
had been used instead of#elseif

evaluate
java.lang.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 evaluating2 + 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 replacingname
