AppendableByteArrayInputStream

public AppendableByteArrayInputStream(byte[] buf)

Method Details

read

public int read()

Overrides:

read in class ByteArrayInputStream

read

public int read(byte[] b,
 int off,
 int len)

Overrides:

read in class ByteArrayInputStream

appendBuffer

public void appendBuffer(byte[] buf,
 int offset,
 int length,
 boolean discard)

Appends new data to the buffer.

Parameters:

buf - Data.

offset - Offset in the data.

length - Length of the data.

discard - True if data which has already been read can be discarded.

setBuffer

public void setBuffer(byte[] buf,
 int offset,
 int length)

Sets the buffer and resets the stream. This will overwrite the data array in the buffer, if it is large enough. Otherwise it will create a new data array and copy the data into it.

Parameters:

buf - Data.

offset - Offset in the data.

length - Length of the data.

main

public static void main(String[] args)
