 Helper function used by CheckFunctionThreadSafety. Split out to allow the ability to examine individual compiled statement lists (e.g. for the ubergraph) KismetCompilerMisc.h  

static bool CheckFunctionThreadSafety ( const FKismetFunctionContext& InContext,
FCompilerResultsLog& InMessageLog,
bool InbEmitErrors
)

 Check the passed-in function to verify its thread safety. This makes sure that it only uses/calls thread-safe functions/nodes. KismetCompilerMisc.h  

static FFieldVariant CheckPropertyNameOnScope ( UStruct* Scope,
const FName& PropertyName
)

 Checks that the property name isn't taken in the given scope (used by CreatePropertyOnScope()) KismetCompilerMisc.h  

static void CompileDefaultProperties ( UClass* Class
)

   KismetCompilerMisc.h  

static void ConsignToOblivion ( UClass* OldClass,
bool bForceNoResetLoaders

static void CreateObjectAssignmentStatement ( FKismetFunctionContext& Context,
UEdGraphNode* Node,
FBPTerminal* SrcTerm,
FBPTerminal* DstTerm,

const FName& PinSubCategory,
UObject* PinSubCategoryObject,
UClass* SelfClass,
bool bIsWeakPointer,
const UEdGraphSchema_K2* Schema,
FCompilerResultsLog& MessageLog
)

 Helper function for creating property for primitive types. KismetCompilerMisc.h  

static FProperty * CreatePropertyOnScope ( UStruct* Scope,
const FName& PropertyName,
const FEdGraphPinType& Type,
UClass* SelfClass,
EPropertyFlags PropertyFlags,
const UEdGraphSchema_K2* Schema,
FCompilerResultsLog& MessageLog,
UEdGraphPin* SourcePin
)

 Creates a property named PropertyName of type PropertyType in the Scope or returns NULL if the type is unknown, but does not link that property in KismetCompilerMisc.h  

static void DetectValuesReturnedByRef ( const UFunction* Func,
const UK2Node* Node,
FCompilerResultsLog& MessageLog
)

 Generate an error for non-const output parameters KismetCompilerMisc.h  

static ConvertibleSignatureMatchResult DoSignaturesHaveConvertibleFloatTypes ( const UFunction* SourceFunction,
const UFunction* OtherFunction
)

 Similar to UFunction::IsSignatureCompatibleWith, but also checks if the function signatures are convertible. KismetCompilerMisc.h  

static FProperty * FindNamedPropertyInScope ( UStruct* Scope,
FName PropertyName,
bool& bIsSparseProperty,
const bool bAllowDeprecated
)

 Finds a property by name, starting in the specified scope, returning NULL if it's not found. KismetCompilerMisc.h  

static const UFunction * FindOverriddenImplementableEvent ( const FName& EventName,
const UClass* Class
)

 Return function, that overrides BlueprintImplementableEvent with given name in given class (super-classes are not considered) KismetCompilerMisc.h  

static FProperty * FindPropertyInScope ( UStruct* Scope,
UEdGraphPin* Pin,
FCompilerResultsLog& MessageLog,
const UEdGraphSchema_K2* Schema,
UClass* SelfClass,
bool& bIsSparseProperty
)

 Finds a property by name, starting in the specified scope; Validates property type and returns NULL along with emitting an error if there is a mismatch. KismetCompilerMisc.h  

static TArray< TSet< UEdGraphNode * > > FindUnsortedSeparateExecutionGroups ( const TArray< UEdGraphNode* >& Nodes

static TTuple< UEdGraphPin *, UEdGraphPin * > GenerateBroadcastFieldNotificationNode ( FKismetCompilerContext& CompilerContext,
UEdGraph* SourceGraph,
UEdGraphNode* SourceNode,
