Detailed Description

A RandomAccessSource that wraps another RandomAccessSource and provides a window of it at a specific offset and over a specific length.

A RandomAccessSource that wraps another RandomAccessSource and provides a window of it at a specific offset and over a specific length. Position 0 becomes the offset position in the underlying source.

Constructor & Destructor Documentation

WindowRandomAccessSource() [1/2]

iText.IO.Source.WindowRandomAccessSource.WindowRandomAccessSource ( IRandomAccessSource  source, long  offset  )

inline

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

Parameters

source	the source
offset	the amount of the offset to use

WindowRandomAccessSource() [2/2]

iText.IO.Source.WindowRandomAccessSource.WindowRandomAccessSource ( IRandomAccessSource  source, long  offset, long  length  )

inline

Constructs a new OffsetRandomAccessSource with an explicit length

Parameters

source	the source
offset	the amount of the offset to use
length	the number of bytes to be included in this RAS
