compileCall

public Calc compileCall(ResolvedFunCall call,
                        ExpCompiler compiler)

Description copied from interface: FunDef

Converts a call to this function into executable objects.

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.

Specified by:

compileCall in interface FunDef

Overrides:

compileCall in class FunDefBase

compileCall3

public Calc compileCall3(ResolvedFunCall call,
                         ExpCompiler compiler)

compileCall2

public Calc compileCall2(ResolvedFunCall call,
                         ExpCompiler compiler)
