Method Summary

Modifier and Type	Method and Description
public int	available() Overrides java.io.InputStream.available. Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking, which may be 0, or 0 when end of stream is detected.
public void	close() Overrides java.io.InputStream.close. Implements java.io.Closeable.close. Closes this input stream and releases any system resources associated with the stream.
private int	Returns: the offset the data starts in out. decode(int in0, int in1, int in2, int in3, int[] out) decode the base 64 encoded input data.
public int	read() Implements abstract java.io.InputStream.read. Reads the next byte of data from the input stream.

public int available() throws IOException Overrides java.io.InputStream.available. Doc from java.io.InputStream.available. Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking, which may be 0, or 0 when end of stream is detected. The read might be on the same thread or another thread. A single read or skip of this many bytes will not block, but may read or skip fewer bytes. Note that while some implementations of `InputStream` will return the total number of bytes in the stream, many will not. It is never correct to use the return value of this method to allocate a buffer intended to hold all data in this stream. A subclass's implementation of this method may choose to throw an `IOException` if this input stream has been closed by invoking the `close()` method. Returns:int an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking or `0` when it reaches the end of the input stream. Exceptions IOException: if an I/O error occurs.

Note that while some implementations of InputStream will return the total number of bytes in the stream, many will not. It is never correct to use the return value of this method to allocate a buffer intended to hold all data in this stream.

A subclass's implementation of this method may choose to throw an IOException if this input stream has been closed by invoking the close() method.

Returns:int

an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking or 0 when it reaches the end of the input stream.

Exceptions

IOException:: if an I/O error occurs.

close	back to summary
public void close() throws IOException Overrides java.io.InputStream.close. Implements java.io.Closeable.close. Doc from java.io.InputStream.close. Closes this input stream and releases any system resources associated with the stream. Exceptions IOException: if an I/O error occurs.

public void close() throws IOException

Overrides java.io.InputStream.close.

Implements java.io.Closeable.close.

Doc from java.io.InputStream.close.

Closes this input stream and releases any system resources associated with the stream.

Exceptions

IOException:: if an I/O error occurs.

decode	back to summary
private int decode(int in0, int in1, int in2, int in3, int[] out) throws EOFException decode the base 64 encoded input data. Returns:int the offset the data starts in out.

decode

back to summary

private int decode(int in0, int in1, int in2, int in3, int[] out) throws EOFException

decode the base 64 encoded input data.

Returns:int: the offset the data starts in out.

read back to summary

read	back to summary
public int read() throws IOException Implements abstract java.io.InputStream.read. Doc from java.io.InputStream.read. Reads the next byte of data from the 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 method blocks until input data is available, the end of the stream is detected, or an exception is thrown. Returns:int the next byte of data, or `-1` if the end of the stream is reached. Exceptions IOException: if an I/O error occurs.
