Detailed Description

Represents an assignment of nbrs to semiaxes, and records the cost of this assignment.

Constructor & Destructor Documentation

◆ Assignment() [1/2]

dialect::Assignment::Assignment	(	const Nbrs &	semis,
		double	cost
	)

inline

Standard constructor.

Parameters

[in]	semis	vector of four shared ptrs to Nbrs, representing the Nbrs assigned to the four semiaxes, starting with East and proceding clockwise. Should be equal to nullptr if no Nbr is present on a given semiaxis.
[in]	cost	the cost of this assignment, which measures the sum of angular displacements of Nbrs from their original positions

◆ Assignment() [2/2]

dialect::Assignment::Assignment ( void )

inline

Default constructor.

Constructs an "empty" Assignment, with no Nbrs and zero cost.

Member Function Documentation

◆ makeUnion()

Assignment Assignment::makeUnion ( const Assignment & other ) const

Create union of two Assignments.

Returns: A new Assignment representing the union of this one with the other.

Note: This function assumes you never try to put more than one Nbr on a given semiaxis. If you do, you will get an incorrect result; an exception will not be raised.

Here is the call graph for this function:

◆ toString()

string Assignment::toString ( void ) const

Write a string representation, listing the id of the Nbr assigned to each semiaxis. For example if Nbrs 3, 7, 8 are assigned to semiaxes E, S, N resp., represent this as "3 7 - 8".

Returns: string representation.
