API Host ClrGetterDelegate

ClrGetterDelegate

Advanced delegate shape for host-backed dynamic getters.

Namespace: AuroraScript.Runtime.Types. Kind: delegate.

Back to .NET Host API Reference

Overview

ClrGetterDelegate computes a property value on demand. The runtime passes the object being read and a ref result slot, so the host can return live state instead of a value captured earlier. Wrap a delegate in BondingGetter to expose it as a script-readable property.

Quick Reference

A minimal use of ClrGetterDelegate.

ClrGetterDelegate getAnswer = (
    ScriptObject target,
    ref ScriptDatum result) =>
{
    result = ScriptDatum.FromNumber(42);
};

Methods

Invoke

void Invoke(ScriptObject @object, ref ScriptDatum result)

Delegate signature invoked by the runtime on each property read.

Parameters

Name	Type	Required	Description
object	ScriptObject	Yes	Object the property is read from.
result	ref ScriptDatum	Yes	Slot receiving the read value.

Returns

None. The read value is written to result.

Behavior

The callback runs on every read, so keep it cheap and free of side effects.

ClrGetterDelegate now = (
    ScriptObject target,
    ref ScriptDatum result) =>
{
    result = ScriptDatum.FromDate(DateTime.UtcNow);
};
