Member Function Documentation

void OSnLNodeVariable::getVariableIndexMap ( std::map< int, int > *  varIdx  )  [virtual]

varIdx is a map where the key is the index of an OSnLNodeVariable and (*varIdx)[ idx] is the kth variable in the map, e.g. (*varIdx)[ 5] = 2 means that variable indexed by 5 is the second variable in the OSnLNode and all of its children

Parameters:
a pointer to a map of the variables in the OSnLNode and its children

Reimplemented from OSnLNode.

Definition at line 1850 of file OSnLNode.cpp.

References idx.

std::string OSnLNodeVariable::getTokenNumber (  )  [virtual]

Returns:
a string token that corresponds to the OSnLNode.

Reimplemented from OSnLNode.

References coef, idx, OSnLNode::inodeInt, and OSnLNode::inumberOfChildren.

std::string OSnLNodeVariable::getTokenName (  )  [virtual]

Returns:
a std::string token that corresponds to the OSnLNode.

Implements OSnLNode.

Definition at line 1789 of file OSnLNode.cpp.

References coef, idx, and OSnLNode::inumberOfChildren.

std::string OSnLNodeVariable::getNonlinearExpressionInXML (  )  [virtual]

Returns:
the OSiL XML for the variable node.

Reimplemented from OSnLNode.

Definition at line 1805 of file OSnLNode.cpp.

References coef, idx, OSnLNode::inumberOfChildren, OSnLNode::m_mChildren, and os_dtoa_format().

double OSnLNodeVariable::calculateFunction ( double *  x  )  [virtual]

Calculate the function value given the current variable values. This is an abstract method which is required to be implemented by the concrete operator nodes that derive or extend from this OSnLNode class.

Parameters:
x holds the values of the variables in a double array.
Returns:
the function value given the current variable values.

Implements OSnLNode.

Definition at line 1834 of file OSnLNode.cpp.

References coef, idx, and OSnLNode::m_dFunctionValue.

OSnLNode * OSnLNodeVariable::cloneOSnLNode (  )  [virtual]

Create or clone a node of this type. This is an abstract method which is required to be implemented by the concrete operator nodes that derive or extend from this OSnLNode class.

Parameters:
x holds the values of the variables in a double array.
Returns:
the function value given the current variable values.

Implements OSnLNode.

References OSnLNodeVariable().

double OSnLNodeVariable::constructADTape ( std::map< int, int > *  ADIdx,
vector< ADdouble > *  XAD 
) [virtual]

The implementation of the virtual functions.

Returns:
a ADdouble.

Implements OSnLNode.
