Method Detail

hoist

public static JsExpression hoist(JsExpression expression)

Given a JsStatement, construct an expression to hoist into the outer caller. This does not perform any name replacement, nor does it verify the scope of referenced elements, but simply constructs a mutable copy of the expression that can be manipulated at-will.

Returns:

A copy of the original expression, or null if the expression cannot be hoisted.
