All Superinterfaces:

GenericNode<JavaNode>, JavaNode, JjtreeNode<JavaNode>, Node, Reportable, TextAvailableNode

All Known Implementing Classes:

ASTRecordPattern, ASTTypePattern, ASTUnnamedPattern

public interface ASTPattern
extends JavaNode

A pattern for pattern matching constructs like InstanceOfExpression or within a ASTSwitchLabel). This is a JDK 16 feature. The ASTRecordPattern is a JDK 21 feature.

This interface is implemented by all forms of patterns.

 Pattern ::=   TypePattern | RecordPattern
