dictionary object
This method returns the number of elements in the dictionary.
uint get_size()
Parameters:
None.
Return value:
The number of elements present in the dictionary, or 0 if the dictionary is empty or if an error occurs.
Remarks:
This method returns the number of key/value pairs in the dictionary. Therefore if the dictionary had a value named "value" linked to a key named "key", the size would return 1.
Example:
// Create a dictionary and display its size.
void main()
{
int value=-1;
dictionary names;
names.set("Damien", 0);
names.set("Philip", 1);
names.set("Percival", 2);
names.set("Byron", 3);
names.set("Humphrey", 4);
alert("Count", "The dictionary contains " + names.get_size() + " entries.");
string[] keys=names.get_keys();
for(int counter=0; counter<:keys.get_size(); counter++)
{
names.get(keys[counter], value);
alert("Names", keys[counter]+" contains the value "+value+".");
}
}
