Type::TableOfIndex -- type for testing tables with specified indices

Introduction

Type::TableOfIndex(obj_type) represents tables with indices (keys) of type obj_type.

Call(s)

testtype(obj, Type::TableOfIndex(obj_type))

Details

Example 1

The following table uses identifiers as keys and integers as values:

>> T := table(a = 1, b = 2, c = 3, d = 4):
   testtype(T, Type::TableOfIndex(DOM_IDENT))
                                   TRUE

Type::TableOfIndex only checks the types of the keys of the table, so the following call returns FALSE:

>> T := table(a = 1, b = 2, c = 3, d = 4):
   testtype(T, Type::TableOfIndex(DOM_INT))
                                   FALSE
>> delete T:
