This class allows an application to create an input stream in
which the bytes read are supplied by the contents of a byte array.
Applications can also read bytes from a string by using a
StringBufferInputStream.
The index of the next character to read from the input stream buffer.
mark
protected int mark
The currently marked position in the stream.
ByteArrayInputStreams are marked at position zero by
default when constructed. They may be marked at another
position within the buffer by the mark() method.
The current buffer position is set to this point by the
reset() method.
count
protected int count
The index one greater than the last valid character in the input
stream buffer.
ByteArrayInputStream
public ByteArrayInputStream(byte buf[])
Creates a new byte array input stream that reads data from the
specified byte array. The byte array is not copied.
Parameters:
buf - the input buffer.
ByteArrayInputStream
public ByteArrayInputStream(byte buf[],
int offset,
int length)
Creates a new byte array input stream that reads data from the
specified byte array. Up to length characters are to
be read from the byte array, starting at the indicated offset.
The byte array is not copied.
Parameters:
buf - the input buffer.
offset - the offset in the buffer of the first byte to read.
length - the maximum number of bytes to read from the buffer.
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.
The read method of ByteArrayInputStream
cannot block.
Returns:
the next byte of data, or -1 if the end of the
stream has been reached.
Returns the number of bytes that can be read from this input
stream without blocking.
The available method of
ByteArrayInputStream returns the value of
count - pos,
which is the number of bytes remaining to be read from the input buffer.
Returns:
the number of bytes that can be read from the input stream
without blocking.
Set the current marked position in the stream.
ByteArrayInputStreams are marked at position zero by
default when constructed. They may be marked at another
position within the buffer by this method.
