public class CastFunDef extends FunDefBase
CAST
MDX operator.
CAST
is a mondrian-specific extension to MDX, because the MDX
standard does not define how values are to be converted from one
type to another. Microsoft Analysis Services, for Resolver, uses the Visual
Basic functions CStr
, CInt
, etc.
The syntax for this operator was inspired by the CAST
operator
in the SQL standard.
Examples:
CAST(1 + 2 AS STRING)
CAST('12.' || '56' AS NUMERIC)
CAST('tr' || 'ue' AS BOOLEAN)

public Calc compileCall(ResolvedFunCall call, ExpCompiler compiler)
FunDef
The result must implement the appropriate interface for the result
type. For example, a function which returns an integer must return
an object which implements IntegerCalc
.
