Method Detail

setConfiguration

public final TransformerBuilder setConfiguration(Config configType,
                                                 String configLocation)

Adds custom configuration mapping defined in a configuration file. Once this method is called it turns off default configuration mapping and user provided configuration is used instead.

Parameters:

configType - configuration file type

configLocation - configuration file location on class path

Returns:

this builder instance

Throws:

ConcurrentModificationException - if this builder instance is used by multiple threads

IllegalStateException - if either build() or this method (with given config type) have been already called

IllegalArgumentException - if method parameter is null or if method parameter equals to empty string

setVerbose

public final TransformerBuilder setVerbose(boolean verbose)

Sets verbosity of underlying transformation engine.

Parameters:

verbose - if output should be verbose or not

Returns:

this builder instance

build

public final ArchiveTransformer build()
                               throws IOException

Creates new resource transformer and closes this builder instance.

Returns:

new resource transformer

Throws:

ConcurrentModificationException - if this builder instance is used by multiple threads

IllegalStateException - if this method have been already called or there was no packages mapping defined in configuration file or if packages mapping count in configuration file surpasses value 65535

IllegalArgumentException - if configuration file has invalid format or it contains identical package mapping or if some package defined in one package mapping is a substring of package in another package mapping

IOException - if configuration reading process failed with unexpected I/O error

buildInternal

protected abstract ArchiveTransformer buildInternal()
                                             throws IOException

Creates new transformer instance.

Returns:

new transformer instance

Throws:

IOException
