Detailed Description

template<typename o_stream>
class RTT::SimpleMarshaller< o_stream >

A simple marshaller which flattens your property bag into simple types.

The representation has the following structure:
typecode, name length, name, ':', value length, value, ';'

For example, to declare a string with contents "value":
Sktest:lvalue;
Except that the k and l would be replaced by byte values four and five.

The typecodes are:

B: booleans
C: single characters
I: ASCII-represented integers
D: ASCII-represented doubles
S: variable length strings

The name length is a single byte and thus limits the length of names to 255 characters. (Zero means zero length.)

The name is an ASCII string representing the name of the property.

The value length is a single byte and thus limits the length of names to 255 characters. (Zero means zero length.)

Member Function Documentation

template<typename o_stream >

virtual void RTT::SimpleMarshaller< o_stream >::flush ( ) [inline, virtual]

Flush all buffers, write footers.

Instructs the Marshaller to flush any remaining buffered data and write a footer to indicate that serialization is done. A marshaller may choose to write nothing until this function is called, or print a summary, or anything else.

Implements RTT::Marshaller.

void RTT::PropertyIntrospection::introspect ( Property< T > & v ) [inline, inherited]

Unknown types must decompose theirselves into the primitives.
