public final class ASTRecordComponent
extends AbstractJjtreeNode<net.sourceforge.pmd.lang.java.ast.AbstractJavaNode,JavaNode>
implements ModifierOwner, SymbolDeclaratorNode

Defines a single component of a RecordDeclaration (JDK 16 feature).

The varargs ellipsis "..." is parsed as an array dimension in the type node.

Record components declare a field, and if a canonical constructor is synthesized by the compiler, also a formal parameter (which is in scope in the body of a compact record constructor). They also may imply the declaration of an accessor method.

• The symbol exposed by the ASTVariableId is the field symbol.
• The symbol exposed by this node (ASTRecordComponent) is a JRecordComponentSymbol.
• The formal parameter symbol is accessible in the formal parameter list of the JConstructorSymbol for the canonical constructor.
• The symbol for the accessor method can be found in the declared methods of the symbol for the record declaration. TODO when we support usage search this needs to be more straightforward

acceptVisitor

protected <P,R> R acceptVisitor(JavaVisitor<? super P,? extends R> visitor,
                                      P data)

isVarargs

public boolean isVarargs()

Returns true if this component's corresponding formal parameter in the canonical constructor of the record is varargs. The type node of this component is in this case an ASTArrayType.

getTypeNode

public ASTType getTypeNode()

getVarId

public ASTVariableId getVarId()

getSymbol

public @NonNull T getSymbol()

Description copied from interface: SymbolDeclaratorNode

Returns the symbol this node declares.

Specified by:

getSymbol in interface SymbolDeclaratorNode

getTypeMirror

public @NonNull JTypeMirror getTypeMirror()

Description copied from interface: TypeNode

Returns the compile-time type of this node. For example, for a string literal, returns the type mirror for String, for a method call, returns the return type of the call, etc.

This method ignores conversions applied to the value of the node because of its context. For example, in 1 + "", the numeric literal will have type int, but it is converted to String by the surrounding concatenation expression. Similarly, in Collections.singletonList(1), the ASTNumericLiteral node has type int, but the type of the method formal is Integer, and boxing is applied at runtime. Possibly, an API will be added to expose this information.

Specified by:

getTypeMirror in interface TypeNode

Returns:

The type mirror. Never returns null; if the type is unresolved, returns TypeSystem.UNKNOWN.
