public CollectionComprehension loop(java.lang.Object loop)

Adds a loop instruction to this comprehension.

The object to add is a loop-like expression, foreach x in someIterable and for (var y=0, y < 5, y = y + 1) in the previous example.

Parameters:

loop - a ForEachLoopStatement or a LoopStatement.

This method should only call the visitor visitXXXX method. The children of this node will be visited by the GoloElement.walk(GoloIrVisitor) method.

Specified by:

accept in class GoloElement<CollectionComprehension>

children

public java.util.List<GoloElement<?>> children()

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

Overrides:

children in class GoloElement<CollectionComprehension>
