Class LibraryDependencyGraph

java.lang.Object

org.apache.flex.compiler.internal.projects.LibraryDependencyGraph

public class LibraryDependencyGraph
extends Object

A dependency graph of libraries. Each vertex on the graph represents a library. Each outgoing edge represents a set of classes that cause the "from" vertex to be dependent on the "to" vertex.

LibraryDependencyGraph

public LibraryDependencyGraph()

Create an empty library dependency graph.

Method Detail

addDependency

public void addDependency(String depender,
                 String dependee,
                 Map<String,DependencyTypeSet> dependencies)

Adds a dependency to the dependency graph.

Parameters:

depender - The absolute path name of the library containing a reference to a definition defined by the other library.

dependee - The absolute path name of the library with a definition referred to by the other library.

addLibrary

public void addLibrary(String library)

Add a ICompilationUnit to the dependency graph.

contains

public boolean contains(String library)

Parameters:

library - An ICompilationUnit to be checked

Returns:

True if the ICompilationUnit unit exists in this DependencyGraph

getDependencySet

public Map<String,DependencyTypeSet> getDependencySet(String from,
                                             String to)

Finds the named dependencies between two compilation units.

Parameters:

from - The depender ICompilationUnit

to - The dependee ICompilationUnit

Returns:

A copied non-synchronous Map from definition qname to a DependencyTypeSet, representing the dependencies between two ICompilationUnits.

getDependencyTypes

public DependencyTypeSet getDependencyTypes(String from,
                                   String to)

Finds the dependencies between two compilation units.

Parameters:

from - The depender ICompilationUnit

to - The dependee ICompilationUnit

Returns:

A copy of a DependencyTypeSet that is active between the two compilation units

getDependencyOrder

public List<String> getDependencyOrder()
                                throws LibraryCircularDependencyException

Throws:

LibraryCircularDependencyException

getDependencies

public Set<String> getDependencies(String libraryPath)

Get the set of all libraries a given library is dependent on.

Parameters:

libraryPath - The absolute path of a library

Returns:

A set of libraries that libraryPath depends on. Each String in the set is the absolute path of a library.
