Public Types

using PropList = std::vector<std::shared_ptr<props::IProperty>>#

Vector of props::IProperty’s shared pointer.

using ParamList = std::vector<std::shared_ptr<param::IParameter>>#

Public Functions

virtual void initialize(const ParamList &param)#

Interface to initialize the operator with the given parameters. The derived class should implement this method to initialize the operator.

Parameters:

param – List of parameters, all should be derived from param::IParameter.

virtual void execute(const PropList &inputs, PropList outputs) const#

Initialize the operator with the given properties and generate the output properties. This function is called after the operator is initialized.

Parameters:

  • inputs – [in] List of input properties. All properties in the input list is readonly.

  • outputs – [out] List of output properties. All output properties are allocated by the caller in advance. The implementer of the Operator can no longer modify the address of the property object in the execute phase, nor can it delete or add a property object, but can only modify the value of each property object.

template<typename OperatorType>
inline const OperatorType &as() const#

Convert the operator into its derived type. Caller should make sure the type is correct. or std::bad_cast will be thrown.

Template Parameters:

OperatorType – The derived class of IOperator.

Returns:

const OperatorType& The derived type of the operator.
