Method Detail

appendPropertyResource

protected void appendPropertyResource(OutputStream outputStream,

                               throws IOException

Append the property resource to the output stream

Parameters:

outputStream - the stream to write to

propertyResource - the cached file of the property resource that contains the property value or the fallback. If null nothing is appended.

Throws:

IOException - in case appending failed

appendResource

protected void appendResource(OutputStream outputStream,
                              ResourceDescriptor descriptor,
                              String minimizedSuffix)
                       throws IOException

Append the resource to the output stream

Parameters:

outputStream - the stream to write to

descriptor - the descriptor of the resource to append

minimizedSuffix - the suffix marking the minimized version of a resource or null if the not minimized files should be concatenated

Throws:

IOException - in case appending failed

concatenateResources

public void concatenateResources(File cacheDir,
                                 String fileName,

                                 File propertyResource,
                                 String minimizedSuffix)
                          throws IOException

Concatenate the provided resources and write the result to the given file

Parameters:

cacheDir - the directory to store the file in

fileName - the name of the file to write to
