Enclosing class:

DirectiveNode

static class DirectiveNode.MacroCallNode
extends DirectiveNode

A node in the parse tree representing a macro call. If the template contains a definition like #macro (mymacro $x $y) ... #end, then a call of that macro looks like #mymacro (xvalue yvalue). The call is represented by an instance of this class. The definition itself does not appear in the parse tree.

Evaluating a macro involves temporarily setting the parameter variables ($x $y in the example) to thunks representing the argument expressions, evaluating the macro body, and restoring any previous values that the parameter variables had.

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..
