Method Detail

public void close()

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.

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.

Annotations
@Override
Exceptions
IOException:
if an I/O error occurs.

public int read(final byte[] b, final int off, final int len) throws IOException

Overrides java.io.InputStream.read.

Reads up to len bytes of data from the input stream into an array of bytes.

An attempt is made to read as many as len bytes, but a smaller number may be read. The number of bytes actually read is returned as an integer.

This implementation may return 0 if the underlying SeekableByteChannel is non-blocking and currently hasn't got any bytes available.

Parameters
b:byte[]

Doc from java.io.InputStream.read.

the buffer into which the data is read.

off:int

Doc from java.io.InputStream.read.

the start offset in array b at which the data is written.

len:int

Doc from java.io.InputStream.read.

the maximum number of bytes to read.

Returns:int

Doc from java.io.InputStream.read.

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.

Annotations
@Override
Exceptions
IOException:

Doc from java.io.InputStream.read.

If the first byte cannot be read for any reason other than end of file, or if the input stream has been closed, or if some other I/O error occurs.
