Class WyalFile.Expr.RecordUpdate

java.lang.Object

wybs.lang.SyntacticElement.Impl

wybs.util.AbstractSyntacticItem

wyal.lang.WyalFile.Expr.RecordUpdate

All Implemented Interfaces:

Cloneable, Comparable<wybs.lang.SyntacticItem>, WyalFile.Expr, WyalFile.Stmt, wybs.lang.SyntacticElement, wybs.lang.SyntacticItem

Enclosing interface:

WyalFile.Expr

public static class WyalFile.Expr.RecordUpdate
extends wybs.util.AbstractSyntacticItem
implements WyalFile.Expr

Represents a record update expression of the form "rec[f:=e]" where rec is the source record, f is the field and e is the value expression. This returns a new record which is equivalent to rec but where the element in field f has the value resulting from e.
