Constructor Detail

### AppendableByteArrayInputStream

    public AppendableByteArrayInputStream(byte[] buf,
                                          int offset,
                                          int length)

### AppendableByteArrayInputStream

    public AppendableByteArrayInputStream(byte[] buf)

Method Detail

### read

    public int read()

  Overrides:
    `read` in class `java.io.ByteArrayInputStream`

### read

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

  Overrides:
    `read` in class `java.io.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(java.lang.String[] args)
