Classes

  Type Name Description
Public struct FInternalTypeInfo    
Public struct UStruct FIrisFastArraySerializer Specialization of FFastArraySerializer in order to add state tracking support for Iris Current usage is to inherit from this struct instead of FFastArraySerializer, backwards compatible with existing system as it simply forwards calls to MarkDirty/MarkItemDirty This class could be named FFastArrayReplicationState, but kept the FIrisFastArraySerializer to match old naming for the time being  
Public struct FLastResortPropertyNetSerializerInfo    
Public struct FNamedStructLastResortPropertyNetSerializerInfo    
Public struct FNamedStructPropertyNetSerializerInfo Helper to implement simple default PropetyNetSerializerInfo for structs.  
Public struct FNetReferenceInfo    
Public struct FPropertyNetSerializerInfo Currently we require each supported type to register FPropertyNetSerializerInfo It provides information on what NetSerializer to use for which property and how to build the required NetSerializer config which is used when we build the dynamic descriptor It is possible to register multiple FPropertyNetSerializerInfo for the same PropertyType-class as long as the IsSupportedFunction only matches a single Property, i.e. bool/nativebool enums of different sizes  
Public class FPropertyNetSerializerInfoRegistry This is a simple static registry used by the ReplicationStateDescriptorBuiider when building descriptors using properties  
Public class FPropertyReplicationState ReplicationState created at runtime using a descriptor built from existing reflection data StateBuffer contains storage for all properties described by the descriptor, When polling data from the source object properties we will compare the value with what we have stored in the statebuffer and mark the member as dirty.if the value differs  
Public struct FReplicationStateDescriptor A ReplicationState is our replication primitive, all members of a ReplicationState has the same high level conditional, i.e. connection level, IsInit, and has the same owner filtering on the block level might be Initial, Connection, Owner Within a ReplicationState we do we also support per member conditionals  
Public class FReplicationStateDescriptorBuilder    
Public struct FReplicationStateHeader A ReplicationState always contains a ReplicationStateHeader which we use to bind replication states for dirty tracking  
Public struct FReplicationStateHeaderAccessor Internal access, should only be used by internal code  
Public struct FReplicationStateIdentifier    
Public struct FReplicationStateMemberChangeMaskDescriptor MemberChangeMaskDescriptor - Data needed for tracking of dirty members.  
Public struct FReplicationStateMemberDebugDescriptor Per member debug descriptor, not strictly needed as long as we have the property list.  
Public struct FReplicationStateMemberDescriptor MemberDescriptors - Offset to where to find member data in both external and internal representation.  
Public struct FReplicationStateMemberFunctionDescriptor    
Public struct FReplicationStateMemberLifetimeConditionDescriptor    
Public struct FReplicationStateMemberPropertyDescriptor Additional data required to call RepNotifies etc.  
Public struct FReplicationStateMemberReferenceDescriptor We store information about all members that store references to other objects in order to allow us to quickly iterate over all references.  
Public struct FReplicationStateMemberRepIndexToMemberIndexDescriptor To be able to enable/disable custom conditional properties we need a fast way to go from RepIndex to MemberIndex.  
Public struct FReplicationStateMemberSerializerDescriptor MemberSerializer - What serializer and config to use for the given member.  
Public struct FReplicationStateMemberTagDescriptor    
Public struct FReplicationStateMemberTraitsDescriptor    
Public struct UStruct FSupportsStructNetSerializerConfig    
Public struct TSimplePropertyNetSerializerInfo Helper to implement simple default PropertyNetSerializerInfo for primitive types.  
Public class UClass Transient, Config UReplicationStateDescriptorConfig

Functions

  Type Name Description
Public function    
Public function    
Public function uint32  
Public function decltype(sizeof(StructName))

UE::Net::IsDeclaredType ( StructName*
)

 This function should be called in the following way to take advantage of SFINAE and perform compile-time error checking for declared types: static_assert(IsDeclaredType((struct MyStruct*)Ptr), "Error message..");
Public function auto  
Public function void Mark the Replication State Header as dirty so it can be copied in the CopyDirtyState pass.
Public function Static uint32

UE::Net::Private::CalculateWordCountForChangeMask ( const T& ChangeMaskDescriptors
)

  
Public function uint32

UE::Net::Private::GetInternalMemberOffset ( const FReplicationStateMemberDescriptor* MemberDescriptors,
const FInternalTypeInfo* InternalTypeInfo,
uint32 MemberIndex
)

  
Public function uint16

UE::Net::Private::GetInternalStateAlignment ( const T& MemberDescriptors,
const FInternalTypeInfo* InternalTypeInfo
)

  
Public function uint32

UE::Net::Private::GetInternalStateSize ( const T& MemberDescriptors,
const FInternalTypeInfo* InternalTypeInfo
)

  
Public function FNetBitArrayView Get MemberChangeMask
Public function uint32

UE::Net::Private::GetMemberChangeMaskSize ( const T& MemberChangeMaskDescriptors
)

  
Public function FNetBitArrayView Get MemberConditionalChangeMask. Valid if state has lifetime conditionals.
Public function UE::Net::FReplicationStateHeader & Get FReplicationStateHeader from a ReplicationState
Public function bool  
Public function void Mark specific member dirty, if this is the first bit marked as dirty in the local MemberChangeMask and the state is bound, mark owning object as dirty as well.
