void PropertyMeshKernel::Paste ( const App::Property from)
virtual

Paste the value from the property (mainly for Undo/Redo and transactions)

Implements App::Property.

References App::Property::aboutToSetValue(), and App::Property::hasSetValue().

void PropertyMeshKernel::Restore ( Base::XMLReader )
virtual

This method is used to restore properties from an XML document.

It uses the XMLReader class, which bases on SAX, to read the in Save() written information. Again the Vector as an example:

void PropertyVector::Restore(Base::XMLReader &reader)
{
// read my Element
reader.readElement("PropertyVector");
// get the value of my Attribute
_cVec.x = reader.getAttributeAsFloat("valueX");
_cVec.y = reader.getAttributeAsFloat("valueY");
_cVec.z = reader.getAttributeAsFloat("valueZ");
}

Implements Base::Persistence.

References App::Property::aboutToSetValue(), Base::XMLReader::addFile(), MeshCore::MeshKernel::Adopt(), Base::XMLReader::getAttribute(), App::Property::hasSetValue(), MeshCore::MeshInput::LoadXML(), and Base::XMLReader::readElement().

void PropertyMeshKernel::RestoreDocFile ( Base::Reader )
virtual

This method is used to restore large amounts of data from a file In this method you simply stream in your with SaveDocFile() saved data.

Again you have to apply for the call of this method in the Restore() call:

{
reader.readElement("Mesh");
std::string file (reader.getAttribute("file") );
if(file == "")
{
// read XML
MeshCore::MeshDocXML restorer(*_pcMesh);
restorer.Restore(reader);
}else{
// initate a file read
reader.addFile(file.c_str(),this);
}
}

After you issued the reader.addFile() your RestoreDocFile() is called:

{
_pcMesh->Read( reader );
}

Reimplemented from Base::Persistence.

References App::Property::aboutToSetValue(), and App::Property::hasSetValue().

void PropertyMeshKernel::Save ( Base::Writer ) const
virtual

This method is used to save properties to an XML document.

A good example you'll find in PropertyStandard.cpp, e.g. the vector:

void PropertyVector::Save (Writer &writer) const
{
writer << writer.ind() << "<PropertyVector valueX=\"" << _cVec.x <<
"\" valueY=\"" << _cVec.y <<
"\" valueZ=\"" << _cVec.z <<"\"/>" << endl;
}

The writer.ind() expression writes the indentation, just for pretty printing of the XML. As you see, the writing of the XML document is not done with a DOM implementation because of performance reasons. Therefore the programmer has to take care that a valid XML document is written. This means closing tags and writing UTF-8.

See also
Base::Writer

Implements Base::Persistence.

References Base::Writer::addFile(), Base::Writer::ind(), Base::Writer::isForceXML(), MeshCore::MeshOutput::SaveXML(), and Base::Writer::Stream().

void PropertyMeshKernel::SaveDocFile ( Base::Writer ) const
virtual

This method is used to save large amounts of data to a binary file.

Sometimes it makes no sense to write property data as XML. In case the amount of data is too big or the data type has a more effective way to save itself. In this cases it is possible to write the data in a seperate file inside the document archive. In case you want do so you have to re-implement SaveDocFile(). First, you have to inform the framework in Save() that you want do so. Here an example from the Mesh module which can save a (pontetionaly big) triangle mesh:

{
if (writer.isForceXML())
{
writer << writer.ind() << "<Mesh>" << std::endl;
MeshCore::MeshDocXML saver(*_pcMesh);
saver.Save(writer);
}else{
writer << writer.ind() << "<Mesh file=\"" << writer.addFile("MeshKernel.bms", this) << "\"/>" << std::endl;
}

The writer.isForceXML() is an indication to force you to write XML. Regardless of size and effectivness. The second part informs the Base::writer through writer.addFile("MeshKernel.bms", this) that this object wants to write a file with the given name. The method addFile() returns a unique name that then is written in the XML stream. This allows your RestoreDocFile() method to identify and read the file again. Later your SaveDocFile() method is called as many times as you issued the addFile() call:

{
_pcMesh->Write( writer );
}

In this method you can simply stream your content to the file (Base::Writer inheriting from ostream).

Reimplemented from Base::Persistence.

References Base::Writer::Stream().

void PropertyMeshKernel::setPointIndices ( const std::vector< std::pair< unsigned long, Base::Vector3f > > &  inds)
void PropertyMeshKernel::setPyObject ( PyObject value)
virtual

This method copies the content, hence creates an new mesh object to copy the data.

The passed argument can be an instance of the Python wrapper for the mesh object or simply a list of triangles, i.e. a list of lists of three floats.

Reimplemented from Base::BaseClass.

References Mesh::MeshObject::createMeshFromList(), Mesh::MeshPy::getMeshObjectPtr(), setValue(), setValuePtr(), and Mesh::MeshPy::Type.

void PropertyMeshKernel::setValue ( const MeshObject m)
void PropertyMeshKernel::setValue ( const MeshCore::MeshKernel m)

This method sets the mesh by copying the data.

References App::Property::aboutToSetValue(), and App::Property::hasSetValue().

void PropertyMeshKernel::setValuePtr ( MeshObject m)

This method references the passed mesh object and takes possession of it, it does NOT create a copy.

The currently referenced mesh object gets de-referenced and possibly deleted if its reference counter becomes zero. However, the mesh gets saved before if a transaction is open at this time.

Note
Make sure not to reference the internal mesh pointer pf this class in client code. This could lead to crashes if not handled properly.
