◆ Evaluate()

double Kratos::UnaryReshapeExpression::Evaluate ( const IndexType  EntityIndex,
const IndexType  EntityDataBeginIndex,
const IndexType  ComponentIndex 
) const
inlineoverridevirtual

Evalute the expression for the given entity data start index and component index and returns the value.

Parameters
EntityIndexIndex of the entity.
EntityDataBeginIndexIndex at which entity data starts.
ComponentIndexComponent index.
Returns
double Evaluated expression.
Todo:
Move to private.

Implements Kratos::Expression.

◆ GetItemShape()

const std::vector<IndexType> Kratos::UnaryReshapeExpression::GetItemShape ( ) const
inlineoverridevirtual

Get the Shape of the expression.

Returns
const std::vector<IndexType> Size of each dimension is in the vector elements.

Implements Kratos::Expression.

◆ GetMaxDepth()

IndexType Kratos::UnaryReshapeExpression::GetMaxDepth ( ) const
inlineoverridevirtual

Get the Max Depth of the lazy expression tree.

Returns the maximum depth of the lazy expression tree.

Warning
This is a recursive computation, hence this should not be done repeatedly unless necessary.
Returns
IndexType Max depth of the lazy expression tree.

Implements Kratos::Expression.
