class CandidateQuadEdgesUnit extends IntermediateResultUnit

Methods	Description
`getCandidateQuadEdges`	Get an array of edges. It includes all edges that candidate quadrilaterals assembling.
`getCount`	Get the number of edges.
`getCandidateQuadEdge`	Get an edge.
`removeAllCandidateQuadEdges`	Remove all edges.
`removeCandidateQuadEdge`	Remove an edge.
`addCandidateQuadEdge`	Add an edge.
`setCandidateQuadEdge`	Set an edge.

The following methods are inherited from class IntermediateResultUnit.

Method	Description
`getHashId`	Returns the hash ID of the unit.
`getOriginalImageHashId`	Returns the hash ID of the original image.
`getOriginalImageTag`	Returns the image tag of the original image.
`getType`	Returns the type of the intermediate result unit.
`getTransformMatrix`	Returns the transformation matrix via `DSTransformMatrixType`.
`clone`	Creates a copy of the intermediate result unit.
`replace`	Replaces the content of the intermediate result unit.

Get an array of edges. It includes all edges that candidate quadrilaterals assembling.

Edge[] getCandidateQuadEdges();

Return Value

Get an array of Edge.

Get the number of edges.

int getCount();

Return Value

The number of edges.

Get the Edge object at the specified index.

Edge getCandidateQuadEdge(int index);

Parameters

[in] index: The index of the edge.

Return Value

The Edge object as the specified edge.

Remove all edges.

void removeAllCandidateQuadEdges();
