All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public class LinearBufferedInputStream
extends java.io.FilterInputStream

Linear buffered input stream implementation that is growing it's internal buffer linearly when marked. This linear growth actually happens in steps of the specified buffer size.

This implementation is not thread-safe.

Constructor Detail

LinearBufferedInputStream

public LinearBufferedInputStream(java.io.InputStream is,
                                 int bufferSize)

Creates a new linear buffered input stream reading from the specified stream. The underlying buffer will have the specified size to work with.

Parameters:

is - the input stream, must be non-null

bufferSize - the buffer size (in bytes), must be positive

Throws:

java.lang.IllegalArgumentException - in case some of the arguments are not valid
