Step ( UObject* Context,
void*const Z_Param__Result
)

 Functions.
Public function 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.
Public function void

StepCompiledIn ( void* Result
)

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

 Replacement for Step that checks the for byte code, and if none exists, then PropertyChainForCompiledIn is used.
Public function void

StepExplicitProperty ( void*const Result,
FProperty* Property
)

 Replacement for Step that uses an explicitly specified property to unpack arguments

Deprecated Functions
