public ClassHierarchy()

Method Detail

getNode

public ClassNode getNode(String className)

Looks up an already-registered node.

Parameters:

className - internal name of the class

Returns:

the node, or null if the hierarchy has no entry for it

getAllNodes

public Collection<ClassNode> getAllNodes()

Returns:

an unmodifiable view of every node, pool classes and external references alike

getPoolNodes

public Collection<ClassNode> getPoolNodes()

Returns:

a fresh list of the nodes backed by a pool class, excluding external references

isAncestorOf

public boolean isAncestorOf(String ancestorName,
                            String descendantName)

Checks if a class is an ancestor of another class.

Parameters:

ancestorName - The potential ancestor class name

descendantName - The potential descendant class name

Returns:

true if ancestor is a superclass or interface of descendant

findMethodHierarchy

public Set<ClassNode> findMethodHierarchy(String className,
                                          String methodName,
                                          String descriptor)

Finds all classes that declare or inherit a method with the given signature.

Parameters:

className - The starting class name

methodName - The method name

descriptor - The method descriptor

Returns:

Set of ClassNodes that have this method (declared or inherited)

getMethod

public MethodEntry getMethod(String className,
                             String methodName,
                             String descriptor)

Finds a method declared directly on one class, without walking the hierarchy.

Parameters:

className - internal name of the declaring class

methodName - method name to match

descriptor - method descriptor to match

Returns:

the matching entry, or null if the class is unknown, external, or lacks the method

size

public int size()

Returns:

the number of registered nodes

toString

public String toString()

Overrides:

toString in class Object
