Member Function Documentation
◆ allocateSlice()
|
protectedpure virtual |
Directly allocate a slice of the correct type using new.
Implemented in MsmStrategy, and HilbertStrategy.
◆ debugIsValidSlice()
|
protectedpure virtual |
Check that this slice is valid for use with this strategy.
No check need be performed unless DEBUG is defined, making it acceptable to check things using ASSERT. This method should not be called if DEBUG is not defined.
Implemented in MsmStrategy, and HilbertStrategy.
◆ freeSlice()
|
virtual |
It is allowed to delete returned slices directly, but it is better to use freeSlice.
freeSlice can only be called on slices obtained from a method of the same strategy. This allows caching of slices to avoid frequent allocation and deallocation.
Implements SliceStrategy.
Definition at line 39 of file SliceStrategyCommon.cpp.
◆ getPivot()
Used by pivotSplit to obtain a pivot.
Implemented in HilbertStrategy, OptimizeStrategy, and MsmStrategy.
◆ getUseIndependence()
|
protected |
Returns true if independence splits should be performed when possible.
Definition at line 113 of file SliceStrategyCommon.cpp.
◆ getUseSimplification()
|
protectedvirtual |
Returns true if slices should be simplified.
Implements SliceStrategy.
Definition at line 117 of file SliceStrategyCommon.cpp.
◆ newSlice()
|
protected |
Returns a slice from the cache that freeSlice adds to, or allocate a new one using allocateSlice.
This method should be used in place of allocating new slices directly.
Definition at line 65 of file SliceStrategyCommon.cpp.
◆ pivotSplit()
|
protectedvirtual |
Takes over ownership of slice.
Uses the pivot gotten through getPivot.
Definition at line 77 of file SliceStrategyCommon.cpp.
◆ setUseIndependence()
|
virtual |
This method should only be called before calling run().
Implements SliceStrategy.
Reimplemented in OptimizeStrategy.
Definition at line 47 of file SliceStrategyCommon.cpp.
◆ setUseSimplification()
|
virtual |
This method should only be called before calling run().
Implements SliceStrategy.
Definition at line 51 of file SliceStrategyCommon.cpp.
◆ simplify()
|
protectedvirtual |
Simplifies slice and returns true if it changed.
Reimplemented in OptimizeStrategy.
Definition at line 55 of file SliceStrategyCommon.cpp.
Member Data Documentation
◆ _pivotTmp
|
private |
Definition at line 97 of file SliceStrategyCommon.h.
◆ _sliceCache
|
private |
This is the cache maintained through newSlice and freeSlice.
It would make more sense with a stack, but that class has (surprisingly!) proven to have too high overhead, even when it seems to be implemented in terms of vector.
Definition at line 95 of file SliceStrategyCommon.h.
◆ _split
|
protected |
Definition at line 80 of file SliceStrategyCommon.h.
◆ _tasks
|
protected |
This keeps track of pending tasks to process.
These are slices and other events.
