Detailed Description

Abstract class defining the basic interface of a dynamic property.

Constructor & Destructor Documentation

ACG::SceneGraph::OpenMesh::BaseProperty::BaseProperty ( const std::string &  _name = "<unknown>" )

inline

Default constructor.

In OpenMesh all mesh data is stored in so-called properties. We distinuish between standard properties, which can be defined at compile time using the Attributes in the traits definition and at runtime using the request property functions defined in one of the kernels.

If the property should be stored along with the default properties in the OM-format one must name the property and enable the persistant flag with set_persistent().

Parameters

_name

Optional textual name for the property.

Member Function Documentation

virtual size_t ACG::SceneGraph::OpenMesh::BaseProperty::restore ( std::istream &  _istr, bool  _swap  )

pure virtual

Restore self from a binary block. Uses reserve() to set the size of self before restoring.

Implemented in ACG::SceneGraph::OpenMesh::PropertyT< std::string >, ACG::SceneGraph::OpenMesh::PropertyT< bool >, and ACG::SceneGraph::OpenMesh::PropertyT< T >.

virtual void ACG::SceneGraph::OpenMesh::BaseProperty::set_persistent ( bool  _yn )

pure virtual

Enable or disable persistency. Self must be a named property to enable persistency.

Implemented in ACG::SceneGraph::OpenMesh::PropertyT< std::string >, ACG::SceneGraph::OpenMesh::PropertyT< bool >, and ACG::SceneGraph::OpenMesh::PropertyT< T >.

virtual size_t ACG::SceneGraph::OpenMesh::BaseProperty::size_of ( size_t  _n_elem ) const

inlinevirtual

Estimated size of property if it has _n_elem elements. The member returns UnknownSize if the size cannot be estimated.

Reimplemented in ACG::SceneGraph::OpenMesh::PropertyT< std::string >, ACG::SceneGraph::OpenMesh::PropertyT< bool >, and ACG::SceneGraph::OpenMesh::PropertyT< T >.
