Constructor & Destructor Documentation

template<typename Ty>

galois::DGAccumulator< Ty >::DGAccumulator ( )

inline

Default constructor.

Member Function Documentation

template<typename Ty>

DGAccumulator& galois::DGAccumulator< Ty >::operator+= ( const Ty &  rhs )

inline

Adds to accumulated value.

Parameters

rhs	Value to add

Returns

reference to this object

template<typename Ty>

void galois::DGAccumulator< Ty >::operator= ( const Ty  rhs )

inline

Sets current value stored in accumulator.

Parameters

rhs	Value to set

template<typename Ty>

Ty galois::DGAccumulator< Ty >::read ( )

inline

Read the value returned by the last reduce call.

Should call reduce before calling this function if an up to date value is required

Returns

the value of the last reduce call

template<typename Ty>

Ty galois::DGAccumulator< Ty >::read_local ( )

inline

Read local accumulated value.

Returns

locally accumulated value

template<typename Ty>

Ty galois::DGAccumulator< Ty >::reduce ( std::string  runID = std::string() )

inline

Reduce data across all hosts, saves the value, and returns the reduced value.

Parameters

runID

optional argument used to create a statistics timer for later reporting

Returns

The reduced value

template<typename Ty>

Ty galois::DGAccumulator< Ty >::reset ( )

inline

Reset the entire accumulator.

Returns

the value of the last reduce call

template<typename Ty>

void galois::DGAccumulator< Ty >::set ( const Ty  rhs )

inline

Sets current value stored in accumulator.

Parameters

rhs	Value to set
