Detailed Description

template<typename PROPTYPE, typename MeshT>
class OpenMesh::PropertyManager< PROPTYPE, MeshT >

This class is intended to manage the lifecycle of properties. It also defines convenience operators to access the encapsulated property's value.

For C++11, it is recommended to use the factory functions makePropertyManagerFromNew, makePropertyManagerFromExisting, makePropertyManagerFromExistingOrNew to construct a PropertyManager, e.g.

TriMesh mesh;
auto visited = makePropertyManagerFromNew<VPropHandleT<bool>>(mesh, "visited.plugin-example.i8.informatik.rwth-aachen.de");
for (auto vh : mesh.vertices()) {
    if (!visited[vh]) {
        visitComponent(mesh, vh, visited);
    }
}

For C++98, it is usually more convenient to use the constructor explicitly, i.e.

TriMesh mesh;
PropertyManager<VPropHandleT<bool>, TriMesh> visited(mesh, "visited.plugin-example.i8.informatik.rwth-aachen.de");
for (TriMesh::VertexIter vh_it = mesh.begin(); ... ; ...) {
    if (!visited[*vh_it]) {
        visitComponent(mesh, *vh_it, visited);
    }
}

Constructor & Destructor Documentation

template<typename PROPTYPE, typename MeshT>

OpenMesh::PropertyManager< PROPTYPE, MeshT >::PropertyManager ( const PropertyManager< PROPTYPE, MeshT > & )

private

Noncopyable because there aren't no straightforward copy semantics.

template<typename PROPTYPE, typename MeshT>

OpenMesh::PropertyManager< PROPTYPE, MeshT >::PropertyManager	(	MeshT &	mesh,
		const char *	propname,
		bool	existing = `false`
	)

inline

Constructor.

Throws an std::runtime_error if existing is true and no property named propname of the appropriate property type exists.

Parameters

mesh	The mesh on which to create the property.
propname	The name of the property.
existing	If false, a new property is created and its lifecycle is managed (i.e. the property is deleted upon destruction of the PropertyManager instance). If true, the instance merely acts as a convenience wrapper around an existing property with no lifecycle management whatsoever.

		MeshT &	src_mesh,
		const RangeType &	src_range,
		MeshT_2 &	dst_mesh,
		const RangeType_2 &	dst_range
	)

inlinestatic

Copy the values of a property from a source range to a target range. The source range must not be smaller than the target range.

Parameters

prop_name	Name of the property to copy. Must exist on the source mesh. Will be created on the target mesh if it doesn't exist.
src_mesh	Source mesh from which to copy.
src_range	Source range which to copy. Must not be smaller than dst_range.
dst_mesh	Destination mesh on which to copy.
dst_range	Destination range.

		PropertyManager< PROPTYPE_2, MeshT_2 > &	dst_propmanager,
		HandleTypeIterator_2	dst_begin,
		HandleTypeIterator_2	dst_end
	)		const

inline

Conveniently transfer the values managed by one property manager onto the values managed by a different property manager.

Parameters

begin	Start iterator. Needs to dereference to HandleType. Will be used with this property manager.
end	End iterator. (Exclusive.) Will be used with this property manager.
dst_propmanager	The destination property manager.
dst_begin	Start iterator. Needs to dereference to the HandleType of dst_propmanager. Will be used with dst_propmanager.
dst_end	End iterator. (Exclusive.) Will be used with dst_propmanager. Used to double check the bounds.

template<typename PROPTYPE, typename MeshT>

static Proxy OpenMesh::PropertyManager< PROPTYPE, MeshT >::createIfNotExists	(	MeshT &	mesh,
		const char *	propname
	)

inlinestatic

Create a property manager for the supplied property and mesh. If the property doesn't exist, it is created. In any case, lifecycle management is disabled.

Definition at line 299 of file PropertyManager.hh.

template<typename PROPTYPE, typename MeshT>

static Proxy OpenMesh::PropertyManager< PROPTYPE, MeshT >::createIfNotExists	(	MeshT &	mesh,
		const char *	propname,
		const ITERATOR_TYPE &	begin,
		const ITERATOR_TYPE &	end,
		const PROP_VALUE &	init_value
	)

inlinestatic

Like createIfNotExists() with two parameters except, if the property doesn't exist, it is initialized with the supplied value over the supplied range after creation. If the property already exists, this method has the exact same effect as the two parameter version. Lifecycle management is disabled in any case.

template<typename HandleType >

PROPTYPE::reference OpenMesh::PropertyManager< PROPTYPE, MeshT >::operator[] ( const HandleType & handle )

inline

Enables convenient access to the encapsulated property.

Parameters

handle A handle of the appropriate handle type. (I.e. VertexHandle for VPropHandleT, etc.)

Parameters

handle A handle of the appropriate handle type. (I.e. VertexHandle for VPropHandleT, etc.)

Definition at line 378 of file PropertyManager.hh.

template<typename PROPTYPE, typename MeshT>

void OpenMesh::PropertyManager< PROPTYPE, MeshT >::retain ( bool doRetain = true )

inline

Disable lifecycle management for this property.

	)

inline

MeshT mesh;
PropertyManager<VPropHandleT<double>, MeshT> distance(
    mesh, "distance.plugin-example.i8.informatik.rwth-aachen.de");
distance.set_range(
    mesh.vertices_begin(), mesh.vertices_end(),
    std::numeric_limits<double>::infinity());

distance.set_range(
    mesh.vv_begin(vh), mesh.vv_end(vh),
    std::numeric_limits<double>::infinity());

Parameters

begin	Start iterator. Needs to dereference to HandleType.
end	End iterator. (Exclusive.)
