Map

Operators and functions for working with map arrays (map type) are described here. map.typename means that you can specify any type name but in the case of the binary operator this type must be the same in both maps.

Operators

Description

* map.typename

int

Returns the number of elements in the map.

map.typename = map.typename

map.typename

Assignment operator.

map.typename &= map.typename

map.typename

Creates a clone of the map. The new variable will work with the same data set.

map.typename [ str ]

typename

Sets/gets a map value by key.

Functions

Del( map.typename m, str key ) map.typename

The Del function deletes the specified key and its value from the map array. The m parameter is returned.

IsKey( map.typename m, str key ) bool

The IsKey function returns true if there is a value with the specified key in the map and false, otherwise.

Key( map.typename m, int index ) str

The Key function returns the item key by its index. For example, this function can be used in the for loop to get the item key.

for val,i in mymap {
Println("\(Key(mymap, i)):\(val)")
}
