reflect.Value.getDictionaryKeys

Returns the keys of a dictionary.

Syntax

getDictionaryKeys( )
  RETURNS DYNAMIC ARRAY OF STRING

Usage

The getDictionaryKeys() method returns a DYNAMIC ARRAY OF STRING containing the list of keys defined in the dictionary represented by this reflect.Value object.

The reflect.Value object used to call this method must have been created from a DICTIONARY variable, or is a reflect.Value object returned from a method like getField(), and references a dictionary.

Example

IMPORT reflect
MAIN
    DEFINE dic DICTIONARY OF STRING
    DEFINE val reflect.Value
    DEFINE keys DYNAMIC ARRAY OF STRING
    LET dic["key1"] = "aaaaa"
    LET dic["key2"] = "bbbbb"
    LET val = reflect.Value.valueOf( dic )
    LET keys = val.getDictionaryKeys()
    DISPLAY "keys[1] = ", keys[1]
    DISPLAY "keys[2] = ", keys[2]
END MAIN

Shows:

keys[1] = key1
keys[2] = key2
