All Implemented Interfaces:

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

public final class ASTSwitchLabel
extends AbstractJjtreeNode<net.sourceforge.pmd.lang.java.ast.AbstractJavaNode,JavaNode>
implements Iterable<ASTExpression>

Represents either a case or default label inside a switch statement or expression. Since Java 14, labels may have several expressions.

 SwitchLabel ::=  "case" Expression ("," Expression )*
                | "case" "null [ "," "default" ]
                | "case" ( TypePattern | RecordPattern )
                | "default"

 

Note: case null and the case patterns are a Java 21 language feature

Method Details

isDefault

public boolean isDefault()

Returns true if this is the default label.

getExprList

public NodeStream<ASTExpression> getExprList()

Returns the expressions of this label, or an empty list if this is the default label. This does neither contain TypePatterns nor RecordPatterns. To check for this, use isPatternLabel().
