Constructor Detail

InputStreamStreamInput

public InputStreamStreamInput(java.io.InputStream is)

Creates a new InputStreamStreamInput with unlimited size

Parameters:

is - the input stream to wrap

InputStreamStreamInput

public InputStreamStreamInput(java.io.InputStream is,
                              long sizeLimit)

Creates a new InputStreamStreamInput with a size limit

Parameters:

is - the input stream to wrap

sizeLimit - a hard limit of the number of bytes in the given input stream. This is used for internal input validation
