GetVMExternalFunction ( const FVMExternalFunctionBindingInfo& BindingInfo,
void* InstanceData,
FVMExternalFunction& OutFunc
)

 Returns the delegate for the passed function signature.
Public function Virtual Const bool  
Public function Virtual bool

InitPerInstanceData ( void* PerInstanceData,
FNiagaraSystemInstance* SystemInstance
)

 Initializes the per instance data for this interface.

Overridden from UNiagaraDataInterfaceBase

  Type Name Description
Public function Virtual Const void Override this method to provide parameters to the GPU (SRV / UAV / Constants / etc) The most common usage will be to provide a single structure which is nested with other parameters.

Overridden from UObject

  Type Name Description
Public function Virtual void Called after the C++ constructor and after the properties have been initialized, including those loaded from config.
Public function Virtual void Do any object-specific cleanup required immediately after loading an object.
Public function Virtual void Handles reading, writing, and reference collecting using FArchive.

Overridden from UObjectBaseUtility

  Type Name Description
Public function Virtual Const bool Called during cluster construction if the object can be added to a cluster
