public BinaryWriter(java.io.OutputStream out)

Method Detail

close

public void close()
           throws java.io.IOException

Throws:

java.io.IOException

write

public void write(byte[] b)
           throws java.io.IOException

Throws:

java.io.IOException

write

public void write(byte[] b,
                  int off,
                  int len)
           throws java.io.IOException

Throws:

java.io.IOException

writeHugeByteArray

protected void writeHugeByteArray(byte[] array,
                                  int offset,
                                  int length)
                           throws java.io.IOException

Sends the contents of the byte array b directly to the underlying output stream. A subclass might wish to limit the maximal buffer size that is sent in one write operation. To do this, this method must be overridden. Even when overriding this method, the underlying output stream must be aware of receiving send buffers of the size up to REQUEST_MAX bytes.

Throws:

java.io.IOException

writeHugeIntArray

protected void writeHugeIntArray(int[] array,
                                 int offset,
                                 int length)
                          throws java.io.IOException

Throws:

writeHugeDoubleArray

protected void writeHugeDoubleArray(double[] array,
                                    int offset,
                                    int length)
                             throws java.io.IOException

This method is called, if a large double array is marshaled. The default implementation converts the double array into a sequence of bytes by writing it to the internal buffer, and sending it in segment of at most REQUEST_MAX bytes. If a subclass is aware of direct marshaling double arrays, and sending segments larger than REQUEST_MAX bytes, this method can be overridden accordingly. An additional assumption can be made in implementations of this method in subclasses: This method is never called as first method in a remote method invocation. As consequence, the receiving side can assume, that the packet delivering the contents of the array will arrive soon, because the remote invocation is already on its way. The default implementation of this method is therefore conservative, assuming a transport technology with limited maximum message size. This is contrary to the default implementation of writeHugeByteArray().
