Method Detail

evaluateList

public List evaluateList(Evaluator evaluator)

Description copied from interface: ListCalc

Evaluates an expression to yield a list of members or tuples.

The list is immutable if Calc.getResultStyle() yields ResultStyle.MUTABLE_LIST. Otherwise, the caller must not modify the list.

Parameters:

evaluator - Evaluation context

Returns:

A list of members or tuples, never null.

distinct

static List<Object> distinct(List list)

evaluateMemberList

public List<Member> evaluateMemberList(Evaluator evaluator)

Description copied from interface: MemberListCalc

Evaluates an expression to yield a list of members.

The list is immutable if Calc.getResultStyle() yields ResultStyle.MUTABLE_LIST. Otherwise, the caller must not modify the list.

Specified by:

evaluateMemberList in interface MemberListCalc

Overrides:

evaluateMemberList in class AbstractListCalc

Parameters:

evaluator - Evaluation context

Returns:

A list of members, never null.

evaluateTupleList

public List<Member[]> evaluateTupleList(Evaluator evaluator)

Description copied from interface: TupleListCalc

Evaluates an expression to yield a list of tuples.

Each tuple is represented by an array of members.

The list is immutable if Calc.getResultStyle() yields ResultStyle.MUTABLE_LIST. Otherwise, the caller must not modify the list.

Specified by:

evaluateTupleList in interface TupleListCalc

Overrides:

evaluateTupleList in class AbstractListCalc

Parameters:

evaluator - Evaluation context

Returns:

A list of tuples, never null.
