This will return a string of the form "ScopeName.FunctionName" associated with this stack frame: UObject/Stack.h  

void GetStackDescription ( FStringBuilderBase& StringBuilder
) const

 This will append a string of the form "ScopeName.FunctionName" associated with this stack frame UObject/Stack.h  
This will return the StackTrace of the current callstack from the last native entry point UObject/Stack.h  

void GetStackTrace ( FStringBuilderBase& StringBuilder
) const

 This will return the StackTrace of the current callstack from the last native entry point UObject/Stack.h  

const uint8 PeekCode()

 Returns the current script op code UObject/Stack.h  

T Read()

   UObject/Stack.h  

CodeSkipSizeType ReadCodeSkipCount ()

 Reads a value from the bytestream, which represents the number of bytes to advance the code pointer for certain expressions. UObject/Stack.h

void*const Z_Param__Result
)

 Functions. UObject/Stack.h  

bool StepAndCheckMostRecentProperty ( UObject* Context,
void*const Z_Param__Result
)

 Convenience function that calls Step, but also returns true if both MostRecentProperty and MostRecentPropertyAddress are non-null. UObject/Stack.h  

void StepCompiledIn ( void* Result
)

 Replacement for Step that checks the for byte code, and if none exists, then PropertyChainForCompiledIn is used. UObject/Stack.h
