Support_ASimpleWriterpublic class Support_ASimpleWriter extends Writer | An implementation of {@code OutputStream} that should serve as the
underlying stream for classes to be tested.
In particular this implementation allows to have IOExecptions thrown on demand.
For simplicity of use and understanding all fields are public. |
