FResolveParameterBuffer

A buffer of parameter structs that can be optionally supplied to a UOL when resolving to supply additional context.

API > API/Runtime > API/Runtime/UniversalObjectLocator

A buffer of parameter structs that can be optionally supplied to a UOL when resolving to supply additional context.

Parameter types are registered through IUniversalObjectLocatorModule::RegisterParameterType and are identified by a unique index. Parameter structs are stored contiguously in memory after an array of headers that specify the offset of each parameter type.

Checking for the presence of a specific parameter type is very fast, amounting to a a simple bit operation.
