DataArrayInt * MEDCoupling1DGTUMesh::computeFetchedNodeIds ( ) const

virtual

Finds nodes not used in any cell and returns an array giving a new id to every node by excluding the unused nodes, for which the array holds -1. The result array is a mapping in "Old to New" mode.

Parameters

Returns: DataArrayInt * - a new instance of DataArrayInt. Its length is this->getNumberOfNodes(). It holds for each node of this mesh either -1 if the node is unused or a new id else. The caller is to delete this array using decrRef() as it is no more needed.

void MEDCoupling1DGTUMesh::renumberNodesWithOffsetInConn ( int offset )

virtual

This method renumbers only nodal connectivity in this. The renumbering is only an offset applied. So this method is a specialization of renumberNodesInConn. WARNING, this method does not check that the resulting node ids in the nodal connectivity is in a valid range !

Parameters

[in] offset - specifies the offset to be applied on each element of connectivity.

void MEDCoupling1DGTUMesh::renumberNodesInConn ( const INTERP_KERNEL::HashMap< int, int > & newNodeNumbersO2N )

virtual

Same than renumberNodesInConn(const int *) except that here the format of old-to-new traducer is using map instead of array. This method is dedicated for renumbering from a big set of nodes the a tiny set of nodes which is the case during extraction of a big mesh.

void MEDCoupling1DGTUMesh::renumberNodesInConn ( const int * newNodeNumbersO2N )

Changes ids of nodes within the nodal connectivity arrays according to a permutation array in "Old to New" mode. The node coordinates array is not changed by this method. This method is a generalization of shiftNodeNumbersInConn().

Warning: This method performs no check of validity of new ids. Use it with care !

Parameters

[in] newNodeNumbersO2N - a permutation array, of length this->getNumberOfNodes(), in "Old to New" mode. See Array indexing and numbering for more info on renumbering modes.

Exceptions

virtual

Keeps from this only cells which constituing point id are in the ids specified by [begin,end). The resulting cell ids are stored at the end of the 'cellIdsKept' parameter. Parameter fullyIn specifies if a cell that has part of its nodes in ids array is kept or not. If fullyIn is true only cells whose ids are fully contained in [begin,end) tab will be kept.

MEDCoupling1DGTUMesh * MEDCoupling1DGTUMesh::copyWithNodalConnectivityPacked ( bool & isShallowCpyOfNodalConnn ) const

See the definition of the nodal connectivity pack here. This method tries to build a new instance geometrically equivalent to this, by limiting at most the number of new object (nodal connectivity). Geometrically the returned mesh is equal to this. So if this is already packed, the return value is a shallow copy of this.

Whatever the status of pack of this, the coordinates array of the returned newly created instance is the same than those in this.

Parameters

[out] isShallowCpyOfNodalConnn - tells if the returned instance share the same pair of nodal connectivity arrays (true) or if nodal connectivity arrays are different (false)

Returns: a new object to be managed by the caller.

bool MEDCoupling1DGTUMesh::retrievePackedNodalConnectivity	(	DataArrayInt *&	nodalConn,
		DataArrayInt *&	nodalConnIndx
	)		const

This method allows to compute, if needed, the packed nodal connectivity pair. Indeed, it is possible to store in this a nodal connectivity array bigger than ranges convered by nodal connectivity index array. It is typically the case when nodalConnIndx starts with an id greater than 0, and finishes with id less than number of tuples in this->_conn.

If this looks packed (the front of nodal connectivity index equal to 0 and back of connectivity index equal to number of tuple of nodal connectivity array) true will be returned and respectively this->_conn and this->_conn_indx (with ref counter incremented). This is the classical case.

If nodal connectivity index points to a subpart of nodal connectivity index the packed pair of arrays will be computed (new objects) and returned and false will be returned.

This method return 3 elements.

Parameters

[out]	nodalConn	- a pointer that can be equal to this->_conn if true is returned (general case). Whatever the value of return parameter this pointer can be seen as a new object, that is to managed by the caller.
[out]	nodalConnIndx	- a pointer that can be equal to this->_conn_indx if true is returned (general case). Whatever the value of return parameter this pointer can be seen as a new object, that is to managed by the caller.

Returns: bool - an indication of the content of the 2 output parameters. If true, this looks packed (general case), if true, this is not packed then output parameters are newly created objects.

Exceptions

if	this does not pass MEDCoupling1DGTUMesh::checkConsistencyLight test
