Detailed Description

Abstract class defining the basic interface of a dynamic property.

Constructor & Destructor Documentation

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

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().

_nameOptional textual name for the property.

Member Function Documentation

virtual size_t 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 OpenMesh::PropertyT< std::string >, OpenMesh::PropertyT< bool >, OpenMesh::Kernel_OSG::oPropertyT< GeoProperty >, and OpenMesh::PropertyT< T >.

virtual void OpenMesh::BaseProperty::set_persistent ( bool  _yn)
pure virtual

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

Implemented in OpenMesh::PropertyT< std::string >, OpenMesh::PropertyT< bool >, OpenMesh::Kernel_OSG::oPropertyT< GeoProperty >, and OpenMesh::PropertyT< T >.

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

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

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