Detailed Description

template<typename TValue>
class DerivativeColumn< TValue >

Returns first derivatives of given quantity as stored in storage.

Quantity must contain derivative, checked by assert.

Definition at line 115 of file Column.h.

Member Function Documentation

accumulate()

template<typename TValue >

virtual void DerivativeColumn< TValue >::accumulate ( Storage &  storage, const Dynamic  value, const Size  particleIdx  ) const

inlineoverridevirtual

Reads the value of the column and saves it into the storage, if possible.

Parameters

storage	Particle storage where the value is stored
value	Accumulated value, must be the same type as this column. Checked by assert.
particleIdx	Index of accumulated particle; if larger than current size of the storage, the storage is resized accordingly.

Exceptions

Exception

if value cannot be accumulated.

Implements ITextColumn.

Definition at line 134 of file Column.h.

evaluate()

template<typename TValue >

virtual Dynamic DerivativeColumn< TValue >::evaluate ( const Storage &  storage, const Statistics &  UNUSEDstats, const Size  particleIdx  ) const

getName()

template<typename TValue >

virtual std::string DerivativeColumn< TValue >::getName ( ) const

inlineoverridevirtual

Returns a name of the column.

The name is printed in the header of the output file.

Implements ITextColumn.

Definition at line 148 of file Column.h.

getType()

template<typename TValue >

virtual ValueEnum DerivativeColumn< TValue >::getType ( ) const

inlineoverridevirtual

Returns the value type of the column.

Implements ITextColumn.
