SeekableByteChannel

public final class AzureSeekableByteChannel
implements SeekableByteChannel

A byte channel that maintains a current position.

A channel may only be opened in read mode OR write mode. It may not be opened in read/write mode. Seeking is supported for reads, but not for writes. Modifications to existing files is not permitted--only creating new files or overwriting existing files.

This type is not threadsafe to prevent having to hold locks across network calls.
