Constructor Detail

StreamSource

public StreamSource(java.io.InputStream in)
             throws java.io.IOException

Creates a new StreamSource from the given stream.

This constructor preloads the entire source stream content into a byte buffer. All subsequent input streams are created from this buffer only.

Parameters:

in - the source stream

Throws:

java.io.IOException - if an error occurs

Method Detail

newStream

public java.io.InputStream newStream(int offset,
                                     int length)
                              throws java.io.IOException

Description copied from interface: SharedInputStreamSource

Creates a new stream from the underlying source stream.

The new stream begins at the offset position of the original source stream and its total length is limited to length octets.

The returned input stream may be buffered for a better efficiency.

Specified by:

newStream in interface SharedInputStreamSource

Parameters:

offset - the offset

length - the length

Returns:

the new input stream

Throws:

java.io.IOException - if an error occurs

getSize

public int getSize()

Description copied from interface: SharedInputStreamSource

Returns the size of the base stream.

Specified by:

getSize in interface SharedInputStreamSource

Returns:

the size of the base stream
