Method Detail

getImmediateSubtypes

public java.util.Set<org.apache.bcel.classfile.JavaClass> getImmediateSubtypes(org.apache.bcel.classfile.JavaClass c)

Get immediate subtypes of given class or interface.

Parameters:

c - a class or interface

Returns:

set of immediate subtypes

hasSubtypes

public boolean hasSubtypes(org.apache.bcel.classfile.JavaClass c)

Determine if a class or interface has subtypes

Parameters:

c - a class or interface

Returns:

true if c has any subtypes/interfaces

getAllClasses

public java.util.Set<org.apache.bcel.classfile.JavaClass> getAllClasses()

Get set of all known classes and interfaces.

Returns:

set of all known classes and interfaces

getTransitiveSubtypes

public java.util.Set<org.apache.bcel.classfile.JavaClass> getTransitiveSubtypes(org.apache.bcel.classfile.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

getTransitiveCommonSubtypes

public java.util.Set<org.apache.bcel.classfile.JavaClass> getTransitiveCommonSubtypes(org.apache.bcel.classfile.JavaClass a,
                                                                                      org.apache.bcel.classfile.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

addApplicationClass

public void addApplicationClass(org.apache.bcel.classfile.JavaClass c)

addClass

public void addClass(org.apache.bcel.classfile.JavaClass c)

extractClassName

public static java.lang.String extractClassName(java.lang.String name)

isApplicationClass

public boolean isApplicationClass(org.apache.bcel.classfile.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
