public class ByteArrayInputStream
extends InputStream
This class implements a buffer that can be used as an InputStream.

Variable Index

o buf
The buffer where data is stored.
o count
The number of characters to use in the buffer.
o pos
The current position in the buffer.

Constructor Index

o ByteArrayInputStream(byte[])
Creates an ByteArrayInputStream from the specified array of bytes.
o ByteArrayInputStream(byte[], int, int)
Creates an ByteArrayInputStream from the specified array of bytes.

Method Index

o available()
Returns the number of available bytes in the buffer.
o read()
Reads a byte of data.
o read(byte[], int, int)
Reads into an array of bytes.
o reset()
Resets the buffer to the beginning.
o skip(long)
Skips n bytes of input.

Variables

o buf 
  protected byte buf[]
The buffer where data is stored.
o pos 
  protected int pos
The current position in the buffer.
o count 
  protected int count
The number of characters to use in the buffer.

Constructors

o ByteArrayInputStream 
  public ByteArrayInputStream(byte buf[])
Creates an ByteArrayInputStream from the specified array of bytes.
Parameters:
buf - the input buffer (not copied)
o ByteArrayInputStream 
  public ByteArrayInputStream(byte buf[],
                              int offset,
                              int length)
Creates an ByteArrayInputStream from the specified array of bytes.
Parameters:
buf - the input buffer (not copied)
offset - the offset of the first byte to read
length - the number of bytes to read

Methods

o read 
  public synchronized int read()
Reads a byte of data.
Returns:
the byte read, or -1 if the end of the stream is reached.
Overrides:
read in class InputStream
o read 
  public synchronized int read(byte b[],
                               int off,
                               int len)
Reads into an array of bytes.
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 actual number of bytes read; -1 is returned when the end of the stream is reached.
Overrides:
read in class InputStream
o skip 
  public synchronized long skip(long n)
Skips n bytes of input.
Parameters:
n - the number of bytes to be skipped
Returns:
the actual number of bytes skipped.
Overrides:
skip in class InputStream
o available 
  public synchronized int available()
Returns the number of available bytes in the buffer.
Overrides:
available in class InputStream
o reset 
  public synchronized void reset()
Resets the buffer to the beginning.
Overrides:
reset in class InputStream
