public long getBodyLength()
throws JMSException (src)
BytesMessage (src)
getBodyLength in interface BytesMessage (src) JMSException (src) - if the JMS provider fails to read the message
due to some internal error.
public boolean readBoolean()
throws JMSException (src)
BytesMessage (src) boolean from the bytes message stream.
readBoolean in interface BytesMessage (src) boolean value read
JMSException (src) - if the JMS provider fails to read the message
due to some internal error.
public byte readByte()
throws JMSException (src)
BytesMessage (src)
readByte in interface BytesMessage (src) byte
JMSException (src) - if the JMS provider fails to read the message
due to some internal error.
public int readBytes(byte[] value)
throws JMSException (src)
BytesMessage (src) If the length of array value is less than the number of
bytes remaining to be read from the stream, the array should
be filled. A subsequent call reads the next increment, and so on.
If the number of bytes remaining in the stream is less than the
length of
array value, the bytes should be read into the array.
The return value of the total number of bytes read will be less than
the length of the array, indicating that there are no more bytes left
to be read from the stream. The next read of the stream returns -1.
readBytes in interface BytesMessage (src) value - the buffer into which the data is read
JMSException (src) - if the JMS provider fails to read the message
due to some internal error.
public int readBytes(byte[] value,
int length)
throws JMSException (src)
BytesMessage (src) If the length of array value is less than the number of
bytes remaining to be read from the stream, the array should
be filled. A subsequent call reads the next increment, and so on.
If the number of bytes remaining in the stream is less than the
length of
array value, the bytes should be read into the array.
The return value of the total number of bytes read will be less than
the length of the array, indicating that there are no more bytes left
to be read from the stream. The next read of the stream returns -1.
If length is negative, or
length is greater than the length of the array
value, then an IndexOutOfBoundsException is
thrown. No bytes will be read from the stream for this exception case.
