Method IsOpaque

Namespace

Ubiquity.NET.Llvm.Types

Assembly

Ubiquity.NET.Llvm.dll

IsOpaque(IPointerType)

Gets a value indicating whether ptr is opaque

public static bool IsOpaque(this IPointerType ptr)

Parameters

ptr IPointerType

Pointer type to test

Returns

bool

true if this pointer is opaque false if it is not

Remarks

An opaque pointer is one where the ElementType is null. This is normal for LLVM now. However, it makes for more complicated code generation. Thus, the types in this wrapper try to keep track of the type of data a pointer is pointing to. This isn't always plausible so it might be opaque. This is normally true for anything retrieved from LLVM IR but is not normal for anything that creates or clones the IR. Since the pointer type creation is done as a method of the thing being pointed to this information is "attached" to the pointer so that the ElementType is not null.

note

until C# 14 [.Net 10] is supported this is an extension method. Once C#14 is available then this can become a property. Default methods on the interface have too many restrictions (mostly egregious is the need to "box"/cast to the explicit interface for the lookup to find the method).
