Constructor Summary

Constructors

Constructor	Description
ArrayType(byte type, int dimensions)	Convenience constructor for array type, for example int[]
ArrayType(String className, int dimensions)	Convenience constructor for reference array type, for example Object[]
ArrayType(Type type, int dimensions)	Constructor for array of given type

Method Summary

Modifier and Type	Method	Description
boolean	equals(Object type)
Type	getBasicType()	Gets the basic type of array, that is, for int[][][] the basic type is int.
String	getClassName()	Gets the name of referenced class.
int	getDimensions()	Gets the number of dimensions of array.
Type	getElementType()	Gets the element type of array, that is, for int[][][] the element type is int[][].

Methods inherited from class ReferenceType

firstCommonSuperclass, getFirstCommonSuperclass, isAssignmentCompatibleWith, isCastableTo

Modifier and Type	Method	Description
ReferenceType	firstCommonSuperclass(ReferenceType t)	Deprecated. Use getFirstCommonSuperclass(ReferenceType t) which has slightly changed semantics.
ReferenceType	getFirstCommonSuperclass(ReferenceType t)	Gets the first common superclass (narrowest ReferenceType referencing a class, not an interface).
boolean	isAssignmentCompatibleWith(Type t)	Tests whether this type is assignment compatible with another type t as defined in the JVM specification; see the AASTORE definition there.
boolean	isCastableTo(Type t)	Tests whether this type is castable to another type t as defined in the JVM specification.
