DynamicPushbackInputStream

public DynamicPushbackInputStream(InputStream in,
                                  int initialSize)

Method Detail

clear

public int clear()

Clear the buffer

shrink

public int shrink()

Shrink the buffer. This will reclaim currently unused space in the buffer, reducing memory but potentially increasing the cost of resizing the buffer

public void unread(byte[] b,
                   int off,
                   int len)
            throws IOException

Overrides:
