Creates a OctetDataWriter.

Method Details

beginObject

public void beginObject()
                 throws IOException

Description copied from interface: DataWriter

Starts writing an object.

A sequence of interleaving calls to DataWriter.name(int) and a value encoding method such as DataWriter.value(int) is expected followed by a final DataWriter.endObject() call.

Specified by:

beginObject in interface DataWriter

Throws:

IOException - If writing fails.

endObject

public void endObject()
               throws IOException

Description copied from interface: DataWriter

Finishes writing the fields of the object started with the last call to DataWriter.beginObject().

Specified by:

endObject in interface DataWriter

Throws:

IOException - If writing fails.

beginArray

public void beginArray(DataType type,
 int length)
                throws IOException

Description copied from interface: DataWriter

Starts writing an array value with entries of the given type.

Specified by:

beginArray in interface DataWriter

Parameters:

type - The type of the array elements.

length - The number of elements that follow.

Throws:

IOException - If writing fails.

endArray

public void endArray()
              throws IOException

Description copied from interface: DataWriter

Stops writing the array started with the last call to DataWriter.beginObject().

Specified by:

endArray in interface DataWriter

Throws:

IOException - If writing fails.

name

public void name(int id)
          throws IOException

Description copied from interface: DataWriter

Writes an identifier of a field fo the currently written object.

Specified by:

name in interface DataWriter

Throws:

IOException - If writing fails.

value

public void value(int value)
           throws IOException

Description copied from interface: DataWriter

Writes an unsigned int value.

Specified by:

value in interface DataWriter

Throws:

IOException - If writing fails.

valueSigned

public void valueSigned(int value)
                 throws IOException

Description copied from interface: DataWriter

Writes a signed int value.

Specified by:

valueSigned in interface DataWriter

Throws:

IOException - If writing fails.

valueFixed

public void valueFixed(int value)
                throws IOException

Description copied from interface: DataWriter

Writes a fixed size 32 bit int value.

Specified by:

valueFixed in interface DataWriter

Throws:

IOException - If writing fails.

value

public void value(float value)
           throws IOException

Description copied from interface: DataWriter

Writes a float value.

Specified by:

value in interface DataWriter

Throws:

IOException - If writing fails.

value

public void value(long value)
           throws IOException

Description copied from interface: DataWriter

Writes an unsigned long value.

Specified by:

value in interface DataWriter

Throws:

IOException - If writing fails.

valueSigned

public void valueSigned(long value)
                 throws IOException

Description copied from interface: DataWriter

Writes a signed long value.

Specified by:

valueSigned in interface DataWriter

Throws:

IOException - If writing fails.

valueFixed

public void valueFixed(long value)
                throws IOException

Description copied from interface: DataWriter

Specified by:

valueFixed in interface DataWriter

Throws:

IOException - If writing fails.

value

public void value(double value)
           throws IOException

Description copied from interface: DataWriter
