Constructor & Destructor Documentation

◆ TensorOperation()

exatn::numerics::TensorOperation::TensorOperation	(	TensorOpCode	opcode,
		unsigned int	num_operands,
		unsigned int	num_scalars
	)

Constructs a yet undefined tensor operation with the specified number of tensor/scalar arguments.

Member Function Documentation

◆ accept()

virtual int exatn::numerics::TensorOperation::accept	(	runtime::TensorNodeExecutor &	node_executor,
		runtime::TensorOpExecHandle *	exec_handle
	)

pure virtual

Accepts tensor node executor (visitor pattern) which will actually execute the tensor operation in an asynchronous fashion, requiring subsequent synchronization via exec_handle. Returns an integer error code (0:Success).

Implemented in exatn::numerics::TensorOpTransform, exatn::numerics::TensorOpContract, exatn::numerics::TensorOpAdd, exatn::numerics::TensorOpCreate, and exatn::numerics::TensorOpDestroy.

◆ getId()

std::size_t exatn::numerics::TensorOperation::getId ( ) const

Returns the unique integer identifier of the tensor operation.

◆ getIndexPattern()

const std::string & exatn::numerics::TensorOperation::getIndexPattern ( ) const

Returns the symbolic tensor operation specification (index pattern).

◆ getNumOperands()

unsigned int exatn::numerics::TensorOperation::getNumOperands ( ) const

Returns the number of tensor operands required for the tensor operation.

◆ getNumOperandsSet()

unsigned int exatn::numerics::TensorOperation::getNumOperandsSet ( ) const

Returns the number of tensor operands set.

◆ getNumScalars()

unsigned int exatn::numerics::TensorOperation::getNumScalars ( ) const

Returns the number of scalar arguments required for the tensor operation.

◆ getNumScalarsSet()

unsigned int exatn::numerics::TensorOperation::getNumScalarsSet ( ) const

Returns the number of scalar arguments set explicitly.

◆ getOpcode()

TensorOpCode exatn::numerics::TensorOperation::getOpcode ( ) const

Returns the tensor operation code (opcode).

◆ getScalar()

std::complex< double > exatn::numerics::TensorOperation::getScalar ( unsigned int scalar_num ) const

Returns a specific scalar argument.

◆ getTensorOperand()

std::shared_ptr< Tensor > exatn::numerics::TensorOperation::getTensorOperand	(	unsigned int	op_num,
		bool *	conjugated = `nullptr`
	)		const

Returns a co-owned pointer to a specific tensor operand, or nullptr if not yet set.

◆ getTensorOperandHash()

TensorHashType exatn::numerics::TensorOperation::getTensorOperandHash ( unsigned int op_num ) const

Returns a unique integer tensor operand identifier.

◆ isSet()

virtual bool exatn::numerics::TensorOperation::isSet ( ) const

pure virtual

Returns TRUE iff the tensor operation is fully set.

Implemented in exatn::numerics::TensorOpTransform, exatn::numerics::TensorOpContract, exatn::numerics::TensorOpAdd, exatn::numerics::TensorOpCreate, and exatn::numerics::TensorOpDestroy.

◆ printIt()

void exatn::numerics::TensorOperation::printIt ( ) const

virtual

Prints.

◆ setId()

void exatn::numerics::TensorOperation::setId ( std::size_t id )

Sets the unique integer identifier of the tensor operation.

◆ setIndexPattern()

void exatn::numerics::TensorOperation::setIndexPattern ( const std::string & pattern )

Sets the symbolic tensor operation specification (index pattern). The tensor operation must have all its tensor/scalar operands set at this point.

◆ setScalar()

void exatn::numerics::TensorOperation::setScalar	(	unsigned int	scalar_num,
		const std::complex< double >	scalar
	)

Sets a specific scalar argument.

◆ setTensorOperand()

void exatn::numerics::TensorOperation::setTensorOperand	(	std::shared_ptr< Tensor >	tensor,
		bool	conjugated = `false`
	)

Sets the next tensor operand.
