Method Detail

addApplicationClass

public void addApplicationClass(JavaClass c)

extractClassName

public static String extractClassName(String originalName)

getAllClasses

public Set<JavaClass> getAllClasses()

Get set of all known classes and interfaces.

Returns: set of all known classes and interfaces

getImmediateSubtypes

public Set<JavaClass> getImmediateSubtypes(JavaClass c)

Get immediate subtypes of given class or interface.

Parameters: c a class or interface

Returns: set of immediate subtypes

getTransitiveCommonSubtypes

public Set<JavaClass> getTransitiveCommonSubtypes(JavaClass a, JavaClass b)

Get set of all known transitive classes and interfaces which are subtypes of both of the given classes and/or interfaces. Note that in this method, we consider a class to be a subtype of itself. Therefore, this method can be used to determine, e.g., if there are any classes implementing both of two given interfaces.

Parameters: a a class or interface b another class or interface

Returns: set of all common subtypes of a and b

getTransitiveSubtypes

public Set<JavaClass> getTransitiveSubtypes(JavaClass c)

Get set of all transitive subtypes of given class or interface, not including the class or interface itself.

Parameters: c a class or interface

Returns: set of all transitive subtypes

hasSubtypes

public boolean hasSubtypes(JavaClass c)

Determine if a class or interface has subtypes

Parameters: c a class or interface

Returns: true if c has any subtypes/interfaces

isApplicationClass

public boolean isApplicationClass(JavaClass javaClass)

Determine whether or not the given class is an application class.

Parameters: javaClass a class

Returns: true if it's an application class, false if not

learnFieldsAndMethods

public static void learnFieldsAndMethods(JavaClass c)
