    • add

      public void add(SourceFile file)
      Adds a source file input to this module.
    • addFirst

      public void addFirst(SourceFile file)
      Adds a source file input to this module.
    • add

      public void add(CompilerInput input)
      Adds a source code input to this module.
    • addFirst

      public void addFirst(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.

      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:

    • clearAsts

      public void clearAsts()
      Removes any references to nodes of the AST. This method is needed to allow the ASTs to be garbage collected if the modules are kept around.
    • sortInputsByDeps

      public void sortInputsByDeps(Compiler compiler)
      Puts the JS files into a topologically sorted order by their dependencies.
    • sortJsModules

      public static JSModule[] sortJsModules(Collection<JSModule> modules) throws SortedDependencies.CircularDependencyException
      Returns the given collection of modules in topological order. Note that this will return the modules in the same order if they are already sorted, and in general, will only change the order as necessary to satisfy the ordering dependencies. This can be important for cases where the modules do not properly specify all dependencies.
      Throws:
      SortedDependencies.CircularDependencyException
