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.

expression

public ExpressionStatement<?> expression()

loops

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>

replaceElement

                              GoloElement<?> newElement)

Replace a child.

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

Specified by:

replaceElement in class GoloElement<CollectionComprehension>

Parameters:

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

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