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

template<class T>

virtual void OpenMesh::PropertyT< T >::set_persistent

(

bool

_yn

)

[inline, virtual]

Enable or disable persistency.

Self must be a named property to enable persistency.

Implements OpenMesh::BaseProperty.

template<class T>

virtual size_t OpenMesh::PropertyT< T >::size_of

(

size_t

_n_elem

)

const [inline, virtual]

Estimated size of property if it has _n_elem elements.

The member returns UnknownSize if the size cannot be estimated.

Reimplemented from OpenMesh::BaseProperty.

template<class T>

virtual size_t OpenMesh::PropertyT< T >::restore	(	std::istream &	_istr,
		bool	_swap
	)			[inline, virtual]

Restore self from a binary block.

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

Implements OpenMesh::BaseProperty.
