Map.exists Method [AX 2012]
Determines whether a particular value exists as a key in the map.
The following example checks whether a particular style exists in a map of styles in a style sheet. If it does, a new name is substituted for the body style.
static void renameStyle(Map stylesheet, str fromName, str toName)
{
str body;
if (stylesheet.exists(fromName))
{
body = stylesheet.lookup (fromName);
stylesheet.remove (fromName);
stylesheet.insert (toName, body);
}
else
{
info (fromName);
}
}
