Constructor Detail

BufferedIndexInput

public BufferedIndexInput()

BufferedIndexInput

public BufferedIndexInput(int bufferSize)

Inits BufferedIndexInput with a specific bufferSize

Method Detail

clone

public Object clone()

getBufferSize

public int getBufferSize()

Returns buffer size. @see #setBufferSize

getFilePointer
