LSPMap Class¶

class localsolver.modeler.LSPMap¶

An LSPMap is a data structure mapping keys to values. A map is both an associative table and an array. Setting a value to an existing key will overwrite any value previously set for that key.

When used as an array-like structure, adding a new unkeyed element to an LSPMap with LSPMap.AddValue automatically assigns an integer key to the element equal to the largest integer key already present plus one, or zero if no integer key exists.

Most of the functions below exist in multiple versions: values and keys can be manipulated through their native type (like int, double, string, LSPMap, LSPFunction…) or manipulated with an LSPValue which is a container that can hold any type of value. Using the native type is more convenient and results in less overhead most of the time. LSPValue should only be used when you don’t know the type of the manipulated value.

The enumerators returned by the method GetEnumerator() follow the fail-fast convention: if the map is structurally modified after the creation of an enumerator (by using the methods Add, Set, Unset or Clear), the enumerator will throw an exception. In other words, you can’t modify a map while you are iterating over it.
