FunctionTable class
- Package:
- adaptive-expressions
FunctionTable is a dictionary which merges BuiltinFunctions.Functions with a CustomDictionary.
Properties
| isReadOnly | Gets a value indicating whether the FunctionTable is readonly. |
| size | Gets the total number of ExpressionFunctions.standardFunctions and user . |
Methods
| add(string, customFunction) | Inserts a mapping of a string key to ExpressionEvaluator into FunctionTable. |
| add(string, ExpressionEvaluator) | Inserts a mapping of a string key to ExpressionEvaluator into FunctionTable. |
| add({ key: string, value: ExpressionEvaluator }) | Inserts a mapping of a string key to ExpressionEvaluator into FunctionTable. |
| clear() | Clears the user . |
| delete(string) | Deletes a specified key from user . |
| entries() | Returns an iterable of key, value pairs for every entry in the map. Not implemented. |
| forEach((value: ExpressionEvaluator, key: string, map: Map<string, ExpressionEvaluator>) => void, any) | Operates on each element of the ExpressionFunctions.standardFunctions. Not implemented. |
| get(string) | Gets a value of ExpressionEvaluator corresponding to the given key. |
| has(string) | Determines if the FunctionTable has a given string key. |
| keys() | Gets a collection of string values that represent the keys of the ExpressionFunctions.standardFunctions. |
| set(string, ExpressionEvaluator) | Sets a value of ExpressionEvaluator corresponding to the given key. |
| values() | Gets a collection of ExpressionEvaluator which is the value of the StandardFunctions. |
