Constructs a new OffsetRandomAccessSource that extends to the end of the underlying source

public WindowRandomAccessSource(IRandomAccessSource source, long offset)

Parameters

source IRandomAccessSource

the source

offset long

the amount of the offset to use

WindowRandomAccessSource(IRandomAccessSource, long, long)

Constructs a new OffsetRandomAccessSource with an explicit length

public WindowRandomAccessSource(IRandomAccessSource source, long offset, long length)

Parameters
