public InputStream()

Method Detail

available

public abstract int available()
                       throws IOException

Returns the number of bytes immediately available for reading from this stream.

Returns:

number of bytes immediately readable

Throws:

IOException - occurs on I/O errors or when the stream is closed

close

public abstract void close()
                    throws IOException

Closes the stream.

Throws:

IOException - if stream is already closed

markSupported

public abstract boolean markSupported()

Checks if mark() and reset() are supported by this stream.

Returns:

true if supported, false if not

mark

public abstract void mark(int readlimit)

reset

public abstract void reset()
                    throws IOException

Throws:

IOException

read

public abstract int read()
                  throws IOException

Reads a single byte from the stream.

Returns:

byte value

Throws:

IOException - occurs on I/O errors or when the stream is closed

read

public void read(byte[] b)
          throws IOException

Reads an array of bytes from the stream. Data is placed in the given array. The method attempts to read as many bytes as fit into the array.

Parameters:

b - array where data is stored

Throws:

IOException - occurs on I/O errors or when the stream is closed

read

public abstract void read(byte[] b,
                          int start,
                          int length)
                   throws IOException

Reads an array of bytes from the stream. Data is placed at the specified location in the given array.

Parameters:

b - array where data is stored

start - offset within the data array

length - number of bytes to read

Throws:

IOException - occurs on I/O errors or when the stream is closed

skip

public abstract void skip(int length)
                   throws IOException

Skips data from the stream.

Parameters:

length - number of bytes to skip

Throws:

IOException - occurs on I/O errors or when the stream is closed
