Examples of com.google.common.io.ByteSink

com.google.common.io.ByteSink
A destination to which bytes can be written, such as a file. Unlike an {@link OutputStream}, a {@code ByteSink} is not an open, stateful stream that can be written to and closed. Instead, itis an immutable supplier of {@code OutputStream} instances.
{@code ByteSink} provides two kinds of methods:
- Methods that return a stream: These methods should return a new, independent instance each time they are called. The caller is responsible for ensuring that the returned stream is closed.
- Convenience methods: These are implementations of common operations that are typically implemented by opening a stream using one of the methods in the first category, doing something and finally closing the stream or channel that was opened.
