sendero_base.Core
This module provides the core for the sendero_base dynamic type system.
Available types are enumerated by the VarT enum. The Var struct represents
a basic value in the type system.
It is recommended that the convenience function set() in sendero_base.Set
and the SenderoObject.add() function (in sendero_base.Object) be used instead
of manipulating the Var struct directly. This will help adjust to API changes.
If you must manipulate the Var struct directly, then try writing a helper function
of your own.
JSON source can be compiled into Var types using the parseJson() function in
sendero_base.json.ObjectParser.

Number
;
- The basic number type in sendero_base dynamic type system (set to real).
- alias
String
;
- The basic string type in sendero_base dynamic type system (set to char[]).
- interface
IObject
;
- The interface for an object in the sendero_base dynamic type system.
- abstract int

(int delegate(ref char[] key, ref Var val) dg);
- abstract Var
opIndex
(char[] key);
- Retrieves a variable in an object through dictionary lookup.
- abstract void
opIndexAssign
(Var val, char[] key);
- Sets the value for the member of an object
- abstract Var
opCall
(Var[] params, IObject ctxt);
- Called when an object is called like a function.
Params:
| Var[] params |
an array of the parameters to the function |
| IObject ctxt |
the context in which the function is called |
Returns:
The return value of the function
- abstract void
toString
(char[] flags, IObject ctxt, void delegate(char[]) write);
- Converts the object to an end-user string representation.
Allows objects to have complex formatting options - useful for any object
that needs a more complex string representation than the basic number/datetime
formatting such as local times, currency, measurements, etc.
Params:
| char[] flags |
flags for string formatting |
| IObject ctxt |
the current execution context |
| void delegate(char[]) write |
a consumer delegate |

- Params:
Returns:
the ith element in the array (if it exists) or a Var of type VarT.Null
