Detailed Description

Overview

Abstract interface class representing a link between two processor groups for exchanging mesh or field data. The two processor groups must have a void intersection (OverlapDEC is to be considered otherwise). The DEC is initialized by attaching a field on the receiving or on the sending side.

The data is sent or received through calls to the (abstract) methods recvData() and sendData().

One can attach either a MEDCoupling::ParaFIELD, or a ICoCo::Field, or directly a MEDCoupling::MEDCouplingFieldDouble instance. See the various signatures of the method DisjointDEC::attachLocalField()

The derivations of this class should be considered for practical instantiation:

DisjointDEC options

The options supported by DisjointDEC objects are the same that the ones supported for all DECs in general and are all inherited from the class DECOptions

◆ attachLocalField() [1/3]

void MEDCoupling::DisjointDEC::attachLocalField ( MEDCouplingFieldDouble * field )

Attaches a local field to a DEC. The method will test whether the processor is on the source or the target side and will associate the mesh underlying the field to the local side.

If the processor is on the receiving end of the DEC, the field will be updated by a recvData() call. Reversely, if the processor is on the sending end, the field will be read, possibly transformed, and sent appropriately to the other side.

◆ attachLocalField() [2/3]

void MEDCoupling::DisjointDEC::attachLocalField	(	const ParaFIELD *	field,
		bool	ownPt = `false`
	)

Attaches a local field to a DEC. If the processor is on the receiving end of the DEC, the field will be updated by a recvData() call. Reversely, if the processor is on the sending end, the field will be read, possibly transformed, and sent appropriately to the other side.

◆ attachLocalField() [3/3]

void MEDCoupling::DisjointDEC::attachLocalField ( const ICoCo::MEDDoubleField * field )

Attaches a local field to a DEC. If the processor is on the receiving end of the DEC, the field will be updated by a recvData() call. Reversely, if the processor is on the sending end, the field will be read, possibly transformed, and sent appropriately to the other side. The field type is a generic ICoCo Field, so that the DEC can couple a number of different fields :
