public class ArrayType

extends Type

Type node for an array type.

Array types are expressed in a recursive manner, one dimension at a time.

 ArrayType:
    Type [ ]
 

Since:

2.0

Method Detail

getNodeType

public int getNodeType()

Description copied from class: ASTNode

Returns an integer value identifying the type of this concrete AST node. The values are small positive integers, suitable for use in switch statements.

For each concrete node type there is a unique node type constant (name and value). The unique node type constant for a concrete node type such as CastExpression is ASTNode.CAST_EXPRESSION.

Specified by:

getNodeType in class ASTNode

Returns:

one of the node type constants

subtreeMatch

public boolean subtreeMatch(ASTMatcher matcher,
                            Object other)

Description copied from class: ASTNode

Returns whether the subtree rooted at the given node matches the given other object as decided by the given matcher.

Specified by:

subtreeMatch in class ASTNode

Parameters:

matcher - the matcher

other - the other object, or null

Returns:

true if the subtree matches, or false if they do not match

getComponentType

public Type getComponentType()

Returns the component type of this array type. The component type may be another array type.

Returns:

the component type node

setComponentType

public void setComponentType(Type componentType)

Sets the component type of this array type. The component type may be another array type.

Parameters:

componentType - the component type

Throws:

IllegalArgumentException - if:

• the node belongs to a different AST
• the node already has a parent
• a cycle in would be created

getElementType

public Type getElementType()

Returns the element type of this array type. The element type is never an array type.

This is a convenience method that descends a chain of nested array types until it reaches a non-array type.

Returns:

the component type node

getDimensions

public int getDimensions()

Returns the number of dimensions in this array type.

This is a convenience method that descends a chain of nested array types until it reaches a non-array type.

Returns:

the number of dimensions (always positive)
