Detailed Description

Represents the arrangement of all Nbrs around a centre node.

Constructor & Destructor Documentation

◆ Arrangement()

Arrangement::Arrangement ( Nbrs nbrs )

Standard constructor.

Parameters

[in] nbrs all the Nbrs of the (implied) centre node

Member Function Documentation

◆ computeAllAssignments()

Assignments Arrangement::computeAllAssignments ( void ) const

Compute all possible Assignments.

Returns: vector of Assignment_SPs. The ordering is such that any and all 4-assignments come first, in order of ascending cost, followed by any and all 3-assignments, again in order of ascending cost, then likewise for 2- and 1-assignments.

Here is the call graph for this function:

◆ computeNAssignments()

Assignments Arrangement::computeNAssignments ( unsigned N ) const

Compute all possible Assignments in which precisely N semiaxes are occupied, sorted by ascending cost.

Parameters

[in] N the number of semiaxes to be occupied

Returns: vector of Assignment_SPs, sorted by ascending cost.

◆ dist()

vector< unsigned > Arrangement::dist ( void ) const

Get the "distribution vector" for this Arrangement.

Returns: vector telling how many Nbrs are in each quadrant

◆ getAssignmentForQuadAction()

Assignment_SP Arrangement::getAssignmentForQuadAction ( std::string quadAction ) const

Get the Assignment resulting from a given quad action.

Parameters

[in] quadAction a string of four letters chosen from among {A, B, C, D}, representing the action to be taken in each of the four quadrants.

Returns: the Assignment resulting from the quad action.

◆ getBasicAssignment()

Assignment_SP Arrangement::getBasicAssignment ( void ) const

Get the "basic Assignment" for this Arrangement.

Returns: the Assignment in which no quad actions have been taken, i.e. in which the semiaxees are just as initially defined, and in which the cost is zero.
