CompoundStructure.MergeRegionsAdjacentToSegment

Method

Description:
Merges the two regions which share the specified segment.

Syntax

public int MergeRegionsAdjacentToSegment(
	int segmentId,
	int layerIdxForMergedRegion
)

Public Function MergeRegionsAdjacentToSegment ( 
	segmentId As Integer,
	layerIdxForMergedRegion As Integer
) As Integer

public:
int MergeRegionsAdjacentToSegment(
	int segmentId, 
	int layerIdxForMergedRegion
)

member MergeRegionsAdjacentToSegment : 
        segmentId : int * 
        layerIdxForMergedRegion : int -> int

Parameters

Parameter	Type	Description
segmentId	Int32	The id of a segment in the underlying grid.
layerIdxForMergedRegion	Int32	The index of the layer to which the resulting region will be associated.

Return Value

Type	Description
Int32	The id of the resulting region. If -1 is returned, then the operation would have produced an invalid region and was not performed.

Exceptions

Exception	Condition
ArgumentOutOfRangeException	The layer index is out of range.
InvalidOperationException	Split and merge regions operations can be used only for vertically compound structures without variable thickness layers. -or- The segment is not shared by adjacent regions.
