)

 Generic (struct) implementation PropertyTypeCompatibility.h  

bool PropertyPathHelpers::GetPropertyValue ( UObject* InContainer,
const FString& InPropertyPath,
T& OutValue
)

 Get the value represented by this property path. PropertyPathHelpers.h  

bool PropertyPathHelpers::GetPropertyValue ( UObject* InContainer,
const FCachedPropertyPath& InPropertyPath,
T& OutValue
)

 Get the value represented by this property path. PropertyPathHelpers.h  

bool PropertyPathHelpers::GetPropertyValue ( UObject* InContainer,
const FCachedPropertyPath& InPropertyPath,
T& OutValue,
FProperty*& OutProperty
)

 Get the value and the leaf property represented by this property path. PropertyPathHelpers.h  

bool PropertyPathHelpers::GetPropertyValue ( UObject* InContainer,
const FString& InPropertyPath,
T& OutValue,
FProperty*& OutProperty
)

 Get the value and the leaf property represented by this property path. PropertyPathHelpers.h  

bool PropertyPathHelpers::GetPropertyValueFast ( UObject* InContainer,
const FCachedPropertyPath& InPropertyPath,
T& OutValue

bool PropertyPathHelpers::GetPropertyValueFast ( UObject* InContainer,
const FCachedPropertyPath& InPropertyPath,
T& OutValue,
FProperty*& OutProperty
)

 Get the value and the leaf property represented by this property path, forcing the use of cached addresses whether or not the path resolves over object or dynamic array boundaries. PropertyPathHelpers.h  

bool PropertyPathHelpers::SetPropertyValue ( UObject* InContainer,
const FCachedPropertyPath& InPropertyPath,
const T& InValue
)

 Set the value and the leaf property represented by this property path If the cached property path has a cached address it will use that as a 'fast path' instead of iterating the path. PropertyPathHelpers.h  

bool PropertyPathHelpers::SetPropertyValue ( UObject* InContainer,
const FString& InPropertyPath,
const T& InValue
)

 Set the value and the leaf property represented by this property path If the cached property path has a cached address it will use that as a 'fast path' instead of iterating the path. PropertyPathHelpers.h  

bool PropertyPathHelpers::SetPropertyValueFast ( UObject* InContainer,
const FCachedPropertyPath& InPropertyPath,
const T& InValue
)

 Get the value represented by this property path. PropertyPathHelpers.h  

bool PropertyPathHelpersInternal::GetValue ( ContainerType* InContainer,

Static

Name Remarks Include Path Unreal Specifiers

static bool IsConcreteTypeCompatibleWithReflectedType ( FProperty* Property
