compare

include map.e 
namespace map 
public function compare(map map_1_p, map map_2_p, integer scope_p = 'd') 

compares two maps to test equality.

Parameters:

1. map_1_p : A map
2. map_2_p : A map
3. scope_p : An integer that specifies what to compare.
   • 'k' or 'K' to only compare keys.
   • 'v' or 'V' to only compare values.
   • 'd' or 'D' to compare both keys and values. This is the default.

Returns:

An integer,

• -1 if they are not equal.
• 0 if they are literally the same map.
• 1 if they contain the same keys and/or values.

Example 1:

map map_1_p = foo() 
map map_2_p = bar() 
if compare(map_1_p, map_2_p, 'k') >= 0 then 
     ... -- two maps have the same keys
