Detailed Description

template<class T>
class OpenMesh::PropertyT< T >

Default property class for any type T.

The default property class for any type T.

The property supports persistency if T is a "fundamental" type:

  • integer fundamental types except bool: char, short, int, long, long long (__int64 for MS VC++) and their unsigned companions.
  • float fundamentals except long double: float, double
  • OpenMesh vector types

Persistency of non-fundamental types is supported if and only if a specialization of struct IO::binary<> exists for the wanted type.

Member Function Documentation

◆ restore()

template<class T>
virtual size_t OpenMesh::PropertyT< T >::restore ( std::istream &  _istr,
bool  _swap 
)
inlinevirtual

Restore self from a binary block.

Uses reserve() to set the size of self before restoring.

Implements OpenMesh::BaseProperty.

◆ set_persistent()

template<class T>
virtual void OpenMesh::PropertyT< T >::set_persistent ( bool  _yn)
inlinevirtual

Enable or disable persistency.

Self must be a named property to enable persistency.

Implements OpenMesh::BaseProperty.

◆ size_of()

template<class T>
virtual size_t OpenMesh::PropertyT< T >::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 from OpenMesh::BaseProperty.
