add

public void add(SourceFile file)

Adds a source file input to this module.

add

public void add(CompilerInput input)

Adds a source code input to this module.

addAfter

public void addAfter(CompilerInput input,
            CompilerInput other)

Adds a source code input to this module directly after other.

addDependency

public void addDependency(JSModule dep)

Adds a dependency on another module.

remove

public void remove(CompilerInput input)

Removes an input from this module.

removeAll

public void removeAll()

Removes all of the inputs from this module.

getDependencies

public List<JSModule> getDependencies()

Gets the list of modules that this module depends on.

Returns:

A list that may be empty but not null

getAllDependencies

public Set<JSModule> getAllDependencies()

Returns the transitive closure of dependencies starting from the dependencies of this module.

getThisAndAllDependencies

public Set<JSModule> getThisAndAllDependencies()

Returns this module and all of its dependencies in one list.

getInputs

public List<CompilerInput> getInputs()

Gets this module's list of source code inputs.

Returns:

A list that may be empty but not null

getByName

public CompilerInput getByName(String name)

Returns the input with the given name or null if none.

removeByName

public boolean removeByName(String name)

Removes any input with the given name. Returns whether any were removed.

toString

public String toString()

Returns the module name (primarily for debugging).

Overrides:

toString in class Object
