Examples of EncodingInfo

entagged.audioformats.EncodingInfo
This class represents a structure for storing and retrieving information about the codec respectively the encoding parameters.
Most of the parameters are available for nearly each audio format. Some others would result in standard values.
Consider: None of the setter methods will actually affect the audio file. This is just a structure for retrieving information, not manipulating the audio file.

org.geoserver.ows.util.EncodingInfo
Xerces' getEncodingName() method of org.apache.xerces.impl.XMLEntityManager) returns an array with name of encoding scheme and endianness. I decided to create a separate class incapsulating encoding metadata. The may idea behind this is the fact that we will most probably need to save this info somewhere and use it later when writing the response. Beside that, using class makes related code more clear.
