Interface ASTPattern

All Superinterfaces:

JavaNode, Node, ScopedNode

All Known Implementing Classes:

ASTGuardedPattern, ASTTypePattern

public interface ASTPattern
extends JavaNode

A pattern (for pattern matching constructs like InstanceOfExpression or within a ASTSwitchLabel). This is a JDK 16 feature.

This interface will be implemented by all forms of patterns. For now, only type test patterns are supported. Record deconstruction patterns is planned for a future JDK version.
