Detailed Description

Base class for operations that support inversion.

This is a base class for operations that can be inverted. To make an operation invertible, inherit from this class instead of directly from Operation, and implement the getInverseSpecsImpl() method to provide the specifications for creating an inverse operation.

Example usage:

class MyOperation : public InvertibleOperation
{
public:
MyOperation();
// Provide implementation for creating an inverse operation
// Other methods...
};
virtual Operation::Specs getInverseSpecsImpl() const =0
Derived classes must implement this to provide specifications for creating an inverse operation.
Specifications required to fully instantiate an operation.

 Treat unexpected behavior warnings as errors.
 
void registerParameter (ParameterBase *param)

std::vector< ParameterBase * > parameters () const
 Return the list of registered parameters.
 
virtual bool doesNotModifyInput () const
 Returns whether the operation is guaranteed to not modify its input element, either because it computes its output out-of-place or because it is a no-op.
 
const std::stringrecordIdentifier () const
 Get the operation's record identifier.
 
virtual void setRecordIdentifier (const std::string &recordIdentifier)
 Set the operation's record identifier.
