All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

Direct Known Subclasses:

ApacheHttpClient4Executor.ResponseStream

public class SelfExpandingBufferredInputStream
extends java.io.BufferedInputStream

Extension of BufferedInputStream enforcing the contract where reset() always returns to the beginning of the stream, and the internal buffer expands automatically to the total length of content read from the underlying stream.

Method Detail

mark

public void mark(int readlimit)

Not supported. Mark position is always zero.

Overrides:

mark in class java.io.BufferedInputStream

read

public int read()
         throws java.io.IOException

Overrides:

read in class java.io.BufferedInputStream

Throws:

java.io.IOException

read

public int read(byte[] b,
                int off,
                int len)
         throws java.io.IOException

Overrides:

read in class java.io.BufferedInputStream

Throws:

java.io.IOException

read

public int read(byte[] b)
         throws java.io.IOException

Overrides:

read in class java.io.FilterInputStream

Throws:

java.io.IOException

expand

private void expand()
             throws java.io.IOException

Double the current buffer size limit. Reset to zero, then double the buffer size and restore last position in the buffer.

Throws:

java.io.IOException

getBufSize

public int getBufSize()

Return the current maximum size of the internal buffer. This is independent of how much data is actually contained within the buffer.

getCount

public int getCount()

getPos

public int getPos()

getMarkLimit

public int getMarkLimit()

getMarkPos

public int getMarkPos()
