Method Detail

resolve

public FunDef resolve(Exp[] args,
                      Validator validator,
                      int[] conversionCount)

Description copied from interface: Resolver

Given a particular set of arguments the function is applied to, returns the correct overloaded form of the function.

The method must increment conversionCount argument every time it performs an implicit type-conversion. If there are several candidate functions with the same signature, the validator will choose the one which used the fewest implicit conversions.

Parameters:

args - Expressions which this function call is applied to.

validator - Validator

conversionCount - This argument must be an int array with a single element; in effect, it is an in/out parameter. It The method increments the count every time it performs a conversion.

Returns:

The function definition which matches these arguments, or null if no function definition that this resolver knows about matches.

requiresExpression

public boolean requiresExpression(int k)

Description copied from interface: Resolver

Returns whether a particular argument must be a scalar expression. Returns false if any of the variants of this resolver allows a set as its kth argument; true otherwise.

Specified by:

requiresExpression in interface Resolver

Overrides:

requiresExpression in class ResolverBase
