boolean	isImplemented(String name, String desc) Returns true if this class or a transformed parent class contains an implementation of, or abstract placeholder for, the method.
boolean	isInterfaceImplemented(String name) Returns true if the class represented by this data, or any parent data, implements the named interface.
boolean	isOverride(String name, String desc) Returns true if the method is an override of a base class method
boolean	isTransformed() Is this bundle for a transformed class, or for a base class (typically Object)?

public InheritanceData(String packageName)

Method Detail

isTransformed

public boolean isTransformed()

Is this bundle for a transformed class, or for a base class (typically Object)?

Returns:

true if this bundle is for transformed class, false otherwise

createChild

public InheritanceData createChild(String packageName)

Returns a new MethodBundle that represents the methods of a child class of this bundle. The returned bundle will always be transformed.

Parameters:

packageName - the package that the child class will be created in

Returns:

new method bundle

addMethod

public void addMethod(String name,
                      String desc,
                      boolean samePackageOnly)

Adds a new instance method. Only non-private methods should be added (that is, methods which might be overridden in subclasses). This can later be queried to see if any base class implements the method.

Parameters:

name - name of method

desc - describes the parameters and return value of the method

samePackageOnly - whether the method can only be overridden in classes that are in the same package

isImplemented

public boolean isImplemented(String name,
                             String desc)

Returns true if this class or a transformed parent class contains an implementation of, or abstract placeholder for, the method.

Parameters:

name - method name

desc - method descriptor

Returns:

true if this class or a base class implements the method (including abstract methods)

isOverride

public boolean isOverride(String name,
                          String desc)

Returns true if the method is an override of a base class method

Parameters:

name - method name

desc - method descriptor

Returns:

true if a base class implements the method (including abstract methods)

isInterfaceImplemented

public boolean isInterfaceImplemented(String name)

Returns true if the class represented by this data, or any parent data, implements the named interface.

addInterface

public void addInterface(String name)

methodNames

public Set<String> methodNames()

Returns the names of any methods in this bundle, or from any parent bundles.
