Member Function Documentation

evaluate()

template<typename T_Result, typename T_Virtual>

virtual T_Result cla3p::VirtualExpression< T_Result, T_Virtual >::evaluate ( ) const

inlinevirtual

Evaluates the expression.

Evaluates the expression and stores the result in a new object.

evaluateOnNew()

template<typename T_Result, typename T_Virtual>

virtual void cla3p::VirtualExpression< T_Result, T_Virtual >::evaluateOnNew ( T_Result & dest ) const

pure virtual

Evaluates the expression on a return object.

Clears existing data in dest, reallocates and evaluates the expression.

Implemented in cla3p::VirtualConjugate< T_Result >, cla3p::VirtualMinus< T_Result, T_Left, T_Right >, cla3p::VirtualObject< T_Result >, cla3p::VirtualOuter< T_Result, T_Virtual >, cla3p::VirtualPlus< T_Result, T_Left, T_Right >, cla3p::VirtualProduct< T_Result, T_Left, T_Right >, cla3p::VirtualScale< T_Result, T_Virtual >, and cla3p::VirtualTranspose< T_Result >.

evaluateOnExisting()

template<typename T_Result, typename T_Virtual>

virtual void cla3p::VirtualExpression< T_Result, T_Virtual >::evaluateOnExisting ( T_Result & dest ) const

pure virtual

Evaluates the expression on a return object.

Evaluates the expression on the pre-allocated & compatible dest.

Implemented in cla3p::VirtualConjugate< T_Result >, cla3p::VirtualMinus< T_Result, T_Left, T_Right >, cla3p::VirtualObject< T_Result >, cla3p::VirtualOuter< T_Result, T_Virtual >, cla3p::VirtualPlus< T_Result, T_Left, T_Right >, cla3p::VirtualProduct< T_Result, T_Left, T_Right >, cla3p::VirtualScale< T_Result, T_Virtual >, and cla3p::VirtualTranspose< T_Result >.

accumulateOnExisting()

template<typename T_Result, typename T_Virtual>

virtual void cla3p::VirtualExpression< T_Result, T_Virtual >::accumulateOnExisting ( T_Result & dest, T_Scalar coeff ) const

pure virtual

Adds the expression on a return object.

Adds the scaled expression result to the pre-allocated & compatible dest.

Implemented in cla3p::VirtualConjugate< T_Result >, cla3p::VirtualMinus< T_Result, T_Left, T_Right >, cla3p::VirtualObject< T_Result >, cla3p::VirtualOuter< T_Result, T_Virtual >, cla3p::VirtualPlus< T_Result, T_Left, T_Right >, cla3p::VirtualProduct< T_Result, T_Left, T_Right >, cla3p::VirtualScale< T_Result, T_Virtual >, and cla3p::VirtualTranspose< T_Result >.
