Method Detail

evaluate

public Object evaluate(Evaluator evaluator)
Description copied from interface: Calc
Evaluates this expression.

Specified by:
evaluate in interface Calc
Parameters:
evaluator - Provides dimensional context in which to evaluate this expression
Returns:
Result of expression evaluation

dependsOn

public boolean dependsOn(Hierarchy hierarchy)
Description copied from interface: Calc
Returns whether this expression depends upon a given hierarchy.

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:

Specified by:
dependsOn in interface Calc
Parameters:
hierarchy - Hierarchy
Returns:
Whether this expression's result depends upon the current member of the hierarchy

getType

public Type getType()
Description copied from interface: Calc
Returns the type of this expression.

Specified by:
getType in interface Calc

accept

public void accept(CalcWriter calcWriter)
Description copied from interface: Calc
Prints this expression, by accepting a visiting CalcWriter.

Specified by:
accept in interface Calc
Parameters:
calcWriter - Writer

getResultStyle

public ResultStyle getResultStyle()
Description copied from interface: Calc
Returns style in which the result of evaluating this expression is returned.

One application of this method is for the compiler to figure out whether the compiled expression is returning a mutable list. If a mutable list is required, the compiler can create a mutable copy.

Specified by:
getResultStyle in interface Calc
