Detailed Description

Pure interface for strategies to transform explicit arrays into implicit arrays.

The interface has two main components: an EstimateReduction method which estimates by how much this strategy can reduce the memory usage of the array and a Reduce method which returns a reduced array.

◆ IsTypeOf()

static vtkTypeBool vtkToImplicitStrategy::IsTypeOf ( const char *  type)
static

◆ IsA()

virtual vtkTypeBool vtkToImplicitStrategy::IsA ( const char *  name)
virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

Reimplemented in vtkToImplicitTypeErasureStrategy, vtkToImplicitRamerDouglasPeuckerStrategy, vtkToConstantArrayStrategy, and vtkToAffineArrayStrategy.

◆ PrintSelf()

void vtkToImplicitStrategy::PrintSelf ( std::ostream &  os,
vtkIndent  indent

override

◆ SetTolerance()

virtual void vtkToImplicitStrategy::SetTolerance ( double  )
virtual

Getter/Setter for tolerance parameter.

This tolerance controls how close a compressed value needs to be to the actual value to be considered a match in absolute terms.

Default value: 0.001

◆ GetTolerance()

virtual double vtkToImplicitStrategy::GetTolerance ( )
virtual

Getter/Setter for tolerance parameter.

This tolerance controls how close a compressed value needs to be to the actual value to be considered a match in absolute terms.

Default value: 0.001

◆ EstimateReduction()

virtual Optional vtkToImplicitStrategy::EstimateReduction ( vtkDataArray )
pure virtual

Estimate the reduction (if possible) that can be obtained on the array using this strategy.

  • if not possible: the returned Optional.IsSome member will be false
  • if possible: the returned Option.IsSome member will be true with Optional.Value being the reduction factor

Implemented in vtkToImplicitTypeErasureStrategy, vtkToImplicitRamerDouglasPeuckerStrategy, vtkToConstantArrayStrategy, and vtkToAffineArrayStrategy.

◆ Reduce()

virtual vtkSmartPointer<vtkDataArray> vtkToImplicitStrategy::Reduce ( vtkDataArray )
pure virtual

◆ ClearCache()

virtual void vtkToImplicitStrategy::ClearCache ( )
inlinevirtual

Destroy any cached variables present in the object (useful for storing calculation results in-between the estimation and reduction phases).

The default implementation does nothing.

Reimplemented in vtkToImplicitRamerDouglasPeuckerStrategy.
