All Implemented Interfaces:

NodeWithRange<Node>, NodeWithTokenRange<Node>, NodeWithType<ComponentPatternExpr, Type>, Observable, Visitable, HasParentNode<Node>, Cloneable

Direct Known Subclasses:

RecordPatternExpr, TypePatternExpr

public abstract class PatternExpr
extends ComponentPatternExpr
implements NodeWithType<ComponentPatternExpr, Type>

PatternExpr serves as the abstract base class for typed pattern expressions. These patterns may be used as top-level patterns in instanceof expressions and switch labels.
