      • addBundle

        public void addBundle​(java.lang.String fileName,
                      boolean includeInHead)
        Add a JS bundle to the manager.
        Parameters:
        fileName - - name of the JavaScript Bundle file.
        includeInHead - - whether it is needed at the head section of the page

      • getBundles

        public java.util.List<java.lang.String> getBundles​(boolean includeInHead)
        Returns an iterator over the list of JS Bundles.

        public java.util.Iterator<java.lang.String> getAllBundlesAsIterator()

      • getTailUniqueFiles

        public java.util.List<java.lang.String> getTailUniqueFiles​(boolean isDebugMode)
        build a list of unique files to be included in document body steps 1. build a list of unique files in all HEAD Bundles 2. build a list of unique files in all HeAD/TAIL Bundles 3. for dynamic files that are depends-sorted, remove all dependency files that are in the list of unique files built at step 2. now the result of step 3 is the list of files to be included as 'tail' files.
        Parameters:
        isDebugMode - Flag Indicating whether JS bundles are requested in debug mode.
        Returns:
        List

      • addScriptFile

        public void addScriptFile​(java.lang.String fileName,
                          boolean includeInHead)
        Add a script file to the manager.
        Parameters:
        fileName - - name of the JavaScript file.
        includeInHead - - whether it is needed at the head section of the page

      • addInterScriptFileDependency

        public void addInterScriptFileDependency​(java.lang.String fromScriptFileName,
                                         java.lang.String toScriptFileName)
        This method programmatically specify a dependency relationship between two JavaScript files. If JavaScrit file B.js depends on A.js, then the A.js will be regarded as "fromScriptFileName", the B.js will be regarded as the "toScriptFileName". This relationship is represented by a graph. Normally, JavaScriptDependencyAnalyzer can automatically capture most dependency relationships in our JavaScript library by analyzing JavaScript source codes. When it comes to few exceptions that the dependency relationship is unable to be captured, we need to invoke this method to explicitly specify the relationship between two JavaScript files. More importantly, you can use this method to define different relationships on the same file in different pages.
        Parameters:
        fromScriptFileName - - the file name of the JavaScript file which is at the "from" end
        toScriptFileName - - the file name of the JavaScript file which is at the "to" end
