Member Function Documentation

std::ostream & epics::pvData::PVString::dumpValue ( std::ostream &  o ) const

virtual

Puts the PVField raw value to the stream.

Parameters

o	output stream.

Returns

The output stream.

Reimplemented from epics::pvData::PVScalarValue< std::string >.

Definition at line 145 of file PVDataCreateFactory.cpp.

    // we escape, but do not quote, for scalar string
    o<<escape(get());
    return o;
}

void epics::pvData::PVString::serialize ( ByteBuffer *  pbuffer, SerializableControl *  pflusher  ) const

virtual

Serialize field into given buffer.

Parameters

buffer	serialization buffer.
flusher	flush interface.

Reimplemented from epics::pvData::PVScalarValue< std::string >.
