Enclosing class:

DirectiveNode

static class DirectiveNode.SetNode
extends DirectiveNode

A node in the parse tree representing a #set construct. Evaluating #set ($x = 23) will set $x to the value 23. It does not in itself produce any text in the output.

Velocity supports setting values within arrays or collections, with for example $set ($x[$i] = $y). That is not currently supported here.

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..
