Constructor & Destructor Documentation

fr.dyade.aaa.agent.BufferedMessageInputStream.BufferedMessageInputStream

(

)

Creates a BufferedMessageInputStream that uses a buffer with default size.

Definition at line 42 of file BufferedMessageInputStream.java.

fr.dyade.aaa.agent.BufferedMessageInputStream.BufferedMessageInputStream

(

int

size

)

Creates a BufferedMessageInputStream that uses a buffer with specified size.

Parameters:

size

the buffer size.

Exceptions:

IllegalArgumentException

if size is less than 0.

Member Function Documentation

final void fr.dyade.aaa.agent.BufferedMessageInputStream.clean

(

)

[protected]

Resets the stream for a new use. Removes all datas.

final int fr.dyade.aaa.agent.BufferedMessageInputStream.read

(

)

throws IOException [virtual]

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:

the next byte of data, or -1 if the end of the stream is reached.

Exceptions:

IOException

if an I/O error occurs.

Here is the call graph for this function:

final int fr.dyade.aaa.agent.BufferedMessageInputStream.read	(	byte	b[],
		int	off,
		int	len
	)			throws IOException [virtual]

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 method blocks until input data is available, end of file is detected, or an exception is thrown.

Parameters:

	b	the buffer into which the data is read.
	off	the start offset in array b at which the data is written.
	len	the maximum number of bytes to read.

Returns:

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.

Exceptions:

	IOException	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.
	NullPointerException	If b is null.
	IndexOutOfBoundsException	If off is negative, len is negative, or len is greater than b.length - off

Here is the call graph for this function:

final void fr.dyade.aaa.agent.BufferedMessageInputStream.readFully

(

int

length

)

throws IOException [protected, virtual]

Reads length bytes of data from the input stream. This method returns when length bytes are available or if end of stream is reached.
