All Implemented Interfaces:

NodeWithAnnotations<ArrayType>, NodeWithRange<Node>, NodeWithTokenRange<Node>, Observable, Visitable, HasParentNode<Node>, Resolvable<ResolvedType>, Cloneable

public class ArrayType
extends ReferenceType
implements NodeWithAnnotations<ArrayType>

To indicate that a type is an array, it gets wrapped in an ArrayType for every array level it has. So, int[][] becomes ArrayType(ArrayType(int)).

Constructor Details

ArrayType

public ArrayType(Type componentType,
 ArrayType.Origin origin,
 NodeList<AnnotationExpr> annotations)

ArrayType

public ArrayType(Type type,
 AnnotationExpr... annotations)

ArrayType

public ArrayType(TokenRange tokenRange,
 Type componentType,
 ArrayType.Origin origin,
 NodeList<AnnotationExpr> annotations)

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

Method Details

resolve

public ResolvedArrayType resolve()

Specified by:

resolve in interface Resolvable<ResolvedType>

Specified by:

resolve in class Type

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)

getComponentType

public Type getComponentType()

setComponentType

public ArrayType setComponentType(Type componentType)

wrapInArrayTypes

@SafeVarargs
public static Type wrapInArrayTypes(Type type,
 List<ArrayType.ArrayBracketPair>... arrayBracketPairLists)

Takes lists of arrayBracketPairs, assumes the lists are ordered outer to inner and the pairs are ordered left to right. The type gets wrapped in ArrayTypes so that the outermost ArrayType corresponds to the leftmost ArrayBracketPair in the first list.

unwrapArrayTypes

public static Pair<Type,List<ArrayType.ArrayBracketPair>> unwrapArrayTypes(Type type)

Takes a type that may be an ArrayType. Unwraps ArrayTypes until the element type is found.

Returns:

a pair of the element type, and the unwrapped ArrayTypes, if any.

setAnnotations

public ArrayType setAnnotations(NodeList<AnnotationExpr> annotations)

Specified by:

setAnnotations in interface NodeWithAnnotations<ArrayType>

Overrides:

setAnnotations in class Type

getOrigin

public ArrayType.Origin getOrigin()

setOrigin

public ArrayType setOrigin(ArrayType.Origin origin)

asString

public String asString()

Specified by:

asString in class Type

toDescriptor

public String toDescriptor()

Specified by:

toDescriptor in class ReferenceType

clone

public ArrayType clone()

Overrides:

clone in class ReferenceType

getMetaModel

public ArrayTypeMetaModel getMetaModel()

Overrides:

getMetaModel in class ReferenceType

Returns:

get JavaParser specific node introspection information.

replace

public boolean replace(Node node,
 Node replacementNode)

Overrides:

replace in class Type

isArrayType

public boolean isArrayType()

Overrides:

isArrayType in class Type

asArrayType

public ArrayType asArrayType()

Overrides:

asArrayType in class Type

ifArrayType

public void ifArrayType(Consumer<ArrayType> action)

Overrides:

ifArrayType in class Type

toArrayType

public Optional<ArrayType> toArrayType()

Overrides:

toArrayType in class Type

getElementType

public Type getElementType()

Finds the element type, meaning: the type without ArrayTypes around it.

In "int[] a[];", the element type is int.

Overrides:

getElementType in class Type

getArrayLevel

public int getArrayLevel()

returns the array level that is 0 for non array type.

Overrides:

getArrayLevel in class Type
