    Creates a StoreByteArrayInputStream.
    
    Parameters:
    
    buf - the input buffer.
  - DataByteArrayInputStream
```
public DataByteArrayInputStream(Buffer buffer)
```
    Creates a StoreByteArrayInputStream.
    
    Parameters:
    
    buffer - the input buffer.
  - DataByteArrayInputStream
```
public DataByteArrayInputStream()
```
    Creates WireByteArrayInputStream with a minmalist byte array
- Method Detail
  - restart
```
public void restart(Buffer buffer)
```
    reset the StoreByteArrayInputStream to use an new Buffer
    
    Parameters:
    
    buffer -
  - restart
```
public void restart(int size)
```
    re-start the input stream - reusing the current buffer
    
    Parameters:
    
    size -
  - size
```
public int size()
```
    Returns:
    
    the size
  - getRawData
```
public byte[] getRawData()

  - readBuffer
```
public Buffer readBuffer(int len)
```

  - restart
```
public void restart()
```
  - read
```
public int read()
```
    Reads the next byte of data from this input stream. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned.
    This read method cannot block.
    
    Specified by:
    
    read in class java.io.InputStream
    
    Returns:
    
    the next byte of data, or -1 if the end of the stream has been reached.
  - read
```
public int read(byte[] b,
                int off,
                int len)
```
    Reads up to len bytes of data into an array of bytes from this input stream.
    
    Overrides:
    
    read in class java.io.InputStream
    
    Parameters:
    
    b - the buffer into which the data is read.
    
    off - the start offset of the data.
    
    len - the maximum number of bytes read.
    
    Returns:
    
    the total number of bytes read into the buffer, or -1 if there is no more data because the end of the stream has been reached.
  - available
```
public int available()
```
    Overrides:
    
    available in class java.io.InputStream
    
    Returns:
    
    the number of bytes that can be read from the input stream without blocking.
