gololang.ir.ClosureReference

All Implemented Interfaces:

BlockContainer<ClosureReference>

public class ClosureReference
extends ExpressionStatement<ClosureReference>
implements BlockContainer<ClosureReference>

A closure reference.

A closure reference is a wrapper around a golo function, to represent a closure or a lambda. For instance, the golo code:

 foo(|x| -> x + 1)
 

The argument of the call to foo is a ClosureReference wrapping the actual GoloFunction

To ease manipulating this node, it delegate most of its methods to the wrapped target function.

GoloFunction.asClosure(), GoloFunction.asClosureReference()

public void walk(GoloIrVisitor visitor)

Walk the visitor through this node children.

Overrides:

walk in class GoloElement<ClosureReference>

children

Returns a list of all the direct children of this node.

Overrides:

children in class GoloElement<ClosureReference>

replaceElement

protected void replaceElement(GoloElement<?> original,
                              GoloElement<?> newElement)

Replace original with newElement if original is a child of this node and type matches.

Specified by:

replaceElement in class GoloElement<ClosureReference>

Parameters:

original - the original value to replace. Must be a child of this node

newElement - the element to replace with. Type must match.
