Method Detail |

protected java.lang.String getName()
AbstractCalc
The default implementation tries to extract a name from a function call, if any, then prints the last part of the class name.
getName
in class AbstractCalc
public Member evaluateMember(Evaluator evaluator)
MemberCalc
May return the null member (see
Hierarchy.getNullMember()
) but never null.
evaluator
- Evaluation context
public boolean dependsOn(Hierarchy hierarchy)
Calc
If it does not depend on the hierarchy, then re-evaluating the expression with a different member of this context must produce the same answer.
Some examples:[Measures].[Unit Sales]
depends on all dimensions except [Measures]
.
([Measures].[Unit Sales],
[Time].[1997]) > 1000
depends on all hierarchies except [Measures] and [Time].
Filter([Store].[USA].Children,
[Measures].[Unit Sales] < 50)
depends upon all hierarchies except [Store] and [Measures].
How so? Normally the scalar expression would depend upon all hierarchies
except [Measures], but the Filter
function sets the [Store]
context before evaluating the scalar expression, so it is not inherited
from the surrounding context.
