Class VBType

Namespace
RDCore.SDK.Model.Types.Abstract
Assembly
RDCore.SDK.dll

A base abstract class representing any representable data type.

public abstract record VBType : IEquatable<VBType>
Inheritance
VBType
Implements
Derived
Inherited Members

Constructors

VBType(Type?, string, bool) 

protected VBType(Type? managedType, string name, bool isHidden = false)

Parameters

managedType Type
name string
isHidden bool

Properties

DefaultValue

Gets the default value for this data type.

public abstract VBTypedValue DefaultValue { get; }

Property Value

VBTypedValue

Remarks

⚠️ Derived types must back the implementation of this property with a thread-safe private static readonly Lazy<T>. Failure to do so would lock up the static context initialization of the StaticSymbol symbols.

IsHidden

true for any implementation that has no specified semantics (internal types).

public bool IsHidden { get; init; }

Property Value

bool

Remarks

These types are semantically hidden from user code, but still discoverable in the program memory space if they're allocated.

ManagedType

The underlying managed (.net) type that represents this VB type, if any.

[JsonIgnore]
public Type? ManagedType { get; init; }

Property Value

Type

Remarks

👉 A runtime convenience, not serialized: an AST or symbol payload that crosses a process boundary carries the type identity, and the receiving side resolves the singleton VBType (and hence this) from it. Type is not JSON-serializable.

Name

The symbolic name of the type, as it is used in code.

public string Name { get; init; }

Property Value

string

Remarks

For module types, this value is determined by a VB_Name attribute.

Methods

CreateValue(IBindingHandle)

Creates a value of this type bound to handle.

public virtual VBTypedValue CreateValue(IBindingHandle handle)

Parameters

handle IBindingHandle

Returns

VBTypedValue

Remarks

The base implementation throws: only types that can hold a runtime value override this (matches the intent of the removed VBTypedValueFactory.CreateValue(VBType) switch, which returned null for the rest).

PrintMembers(StringBuilder)

Prints this VBType's members for ToString().

protected virtual bool PrintMembers(StringBuilder builder)

Parameters

builder StringBuilder

Returns

bool

Remarks

Deliberately omits DefaultValue: every VBTypedValue carries its own TypeInfo pointing back at the VBType that produced it, so printing DefaultValue here and letting the compiler-generated ToString take its usual course would recurse between the two PrintMembers implementations forever.
