Constructor Detail

ObjectType

public ObjectType(String class_name)

Parameters:

class_name - fully qualified class name, e.g. java.lang.String

Method Detail

getClassName

public String getClassName()

Returns:

name of referenced class

hashCode

public int hashCode()

Overrides:

hashCode in class Type

Returns:

a hash code value for the object.

equals

public boolean equals(Object type)

Overrides:

equals in class Type

Returns:

true if both type objects refer to the same class.

referencesClass

public boolean referencesClass()

Deprecated. this method returns an inaccurate result if the class or interface referenced cannot be found: use referencesClassExact() instead

If "this" doesn't reference a class, it references an interface or a non-existant entity.

referencesInterface

public boolean referencesInterface()

Deprecated. this method returns an inaccurate result if the class or interface referenced cannot be found: use referencesInterfaceExact() instead

If "this" doesn't reference an interface, it references a class or a non-existant entity.

referencesClassExact

public boolean referencesClassExact()
                             throws ClassNotFoundException

Return true if this type references a class, false if it references an interface.

Returns:

true if the type references a class, false if it references an interface

Throws:

ClassNotFoundException - if the class or interface referenced by this type can't be found

referencesInterfaceExact

public boolean referencesInterfaceExact()
                                 throws ClassNotFoundException

Return true if this type references an interface, false if it references a class.

Returns:

true if the type references an interface, false if it references a class

Throws:

ClassNotFoundException - if the class or interface referenced by this type can't be found

subclassOf

public boolean subclassOf(ObjectType superclass)
                   throws ClassNotFoundException

Return true if this type is a subclass of given ObjectType.

Throws:

ClassNotFoundException - if any of this class's superclasses can't be found

accessibleTo

public boolean accessibleTo(ObjectType accessor)
                     throws ClassNotFoundException

Java Virtual Machine Specification edition 2, § 5.4.4 Access Control

Throws:

ClassNotFoundException - if the class referenced by this type can't be found
