BasicSymbolTable

trait BasicSymbolTable[Key, Value] extends AnyRef

This trait represents a symbol table of generic key/value pairs.

It supports the usual put, get, contains, delete, size, and is-empty methods. It also provides a keys method for iterating over all of the keys.

A symbol table implements the associative array abstraction: when associating a value with a key that is already in the symbol table, the convention is to replace the old value with the new value.
