All Implemented Interfaces:

EmbeddedStreamTranslator

public class DefaultEmbeddedStreamTranslator
extends Object
implements EmbeddedStreamTranslator

Loads EmbeddedStreamTranslators via service loading. Tries to run each in turn and returns the first non-null value. If no translation has occurred, this returns the original InputStream. If a translation has occurred, the translator will consume the InputStream but not close it.
