All Implemented Interfaces:

NodeWithFinalModifier<MatchAllPatternExpr>, NodeWithModifiers<MatchAllPatternExpr>, NodeWithRange<Node>, NodeWithTokenRange<Node>, Observable, Visitable, HasParentNode<Node>, Cloneable

public class MatchAllPatternExpr
extends ComponentPatternExpr
implements NodeWithFinalModifier<MatchAllPatternExpr>

MatchAllPatternExpressions were added in JEP456. They are untyped pattern expressions that cannot be used as top-level patterns. MatchAllPatternExpr (`_`) should not be confused with an unnamed TypePatternExpr (`String _`) which does have a type, but does not introduce any variables to scope.

Constructor Detail

MatchAllPatternExpr

public MatchAllPatternExpr(NodeList<Modifier> modifiers)

MatchAllPatternExpr

public MatchAllPatternExpr(TokenRange tokenRange,
                           NodeList<Modifier> modifiers)

This constructor is used by the parser and is considered private.

Method Detail

isFinal

public boolean isFinal()

Specified by:

isFinal in interface NodeWithFinalModifier<MatchAllPatternExpr>

Returns:

true, if the modifier final is explicitly added to this node. If the node is implicitly final without an explicit modifier (e.g. records, and components of a record), this method should be overridden.

getModifiers

public NodeList<Modifier> getModifiers()

Description copied from interface: NodeWithModifiers

Return the modifiers of this variable declaration. Warning: modifying the returned set will not trigger observers, you have to use setModifiers for that.

Specified by:

getModifiers in interface NodeWithModifiers<MatchAllPatternExpr>

Returns:

modifiers

See Also:

Modifier

setModifiers

public MatchAllPatternExpr setModifiers(NodeList<Modifier> modifiers)

Specified by:

setModifiers in interface NodeWithModifiers<MatchAllPatternExpr>

accept

public <R,A> R accept(GenericVisitor<R,A> v,
                            A arg)

Description copied from interface: Visitable

Accept method for visitor support.

Specified by:

accept in interface Visitable

Type Parameters:

R - the type of the return value of the visitor

A - the type the user argument passed to the visitor

Parameters:

v - the visitor implementation

arg - the argument passed to the visitor (of type A)

Returns:

the result of the visit (of type R)

accept

public <A> void accept(VoidVisitor<A> v,
                       A arg)

Description copied from interface: Visitable

Accept method for visitor support.

Specified by:

accept in interface Visitable

Type Parameters:

A - the type the argument passed for the visitor

Parameters:

v - the visitor implementation

arg - any value relevant for the visitor (of type A)
