CatStream Class Reference

Provides data from a concatenation of Streams. Please note that the provided Streams can be played only once! You will need to reset them (e.g. moving the file pointer to the beginning) and readd them back if you want to process them a second time. The default timeout on the available() method is set to 0. This might be not good if you use e.g. a URLStream. More...
