Member Function Documentation

void Washburn::calcAllocation (  void   )  [protected, virtual]

Calculate the allocation using the Washburn algorithm. calcAllocationWashburn() Uses the Washburn algorithm to calculate the optimal assignment of resources to the set of areas. This set of assignments is stored in myAssignments. Author: David Albrecht (DWA) Implements Allocation.

AreaAssignment * Washburn::firstArea (  const int  resource  )  const [protected, virtual]

Returns the area number of the first area in this allocation. firstArea() Returns the first AreaAssignment (an area and a time) that a given resource was assigned to. If the resource does not exist in this allocation a NULL is returned. Author: David Albrecht (DWA) Implements Allocation.

ActiveArea * Washburn::firstArea (  void   )  const [protected, virtual]

Returns the area number of the first area in this allocation. firstArea() Returns the area number of the first area in this allocation. If the allocation is empty, returns -1 Author: David Albrecht (DWA) Implements Allocation.

ResourceAssignment * Washburn::firstRes (  const int  area  )  const [protected, virtual]

Given an area, it returns the first resource assigned to that area. firstRes() Given an area, it returns the first resource assigned to that area (returned as a ResourceAssignment with the resource and time). If there are no resources, it returns a NULL. Author: David Albrecht (DWA) Implements Allocation.

AreaAssignment * Washburn::nextArea (  const int  resource, const int  currentArea )  const [protected, virtual]

Given an area number, returns the next area that has something assigned to it. nextArea() Given a resource and an area, returns the next area (and time) that has this resource assigned to. If there are no more areas or the resource is not assigned to any more areas it returns NULL. Author: David Albrecht (DWA) Implements Allocation.

ActiveArea * Washburn::nextArea (  const int  currentArea  )  const [protected, virtual]

Given an area number, returns the next area that has something assigned to it. nextArea() Given an area number, returns the next area that has something assigned to it in this set of allocations. If there is no other area with an allocation of resources greater than 0, the function returns -1. Author: David Albrecht (DWA) Implements Allocation.

ResourceAssignment * Washburn::nextRes (  const int  area, const int  currentResource )  const [protected, virtual]

Given a resource and an area, it returns the next ResourceAssignment for that area. nextRes() Given a resource and an area, it returns the next resource assigned to that area (as a ResourceAssignment). If there are no next resources, it returns a NULL. Author: David Albrecht (DWA) Implements Allocation.
