Constructors

	Name	Description
	TAttribute()	Default constructor.
	TAttribute ( const OtherType& InInitialValue )	Construct implicitly from an initial value
	TAttribute ( ObjectType&& InInitialValue )	Construct implicitly from moving an initial value
	TAttribute ( TSharedRef< SourceType > InUserObje..., typename FGetter::template TSPMetho... )	Constructs by binding an arbitrary function that will be called to generate this attribute's value on demand.
	TAttribute ( SourceType* InUserObject, typename FGetter::template TSPMetho... )	Constructs by binding an arbitrary function that will be called to generate this attribute's value on demand.

void	Bind ( SourceType* InUserObject, typename FGetter::template TSPMetho... )	Binds an arbitrary function that will be called to generate this attribute's value on demand.
void	Bind ( const FGetter& InGetter )	Binds an arbitrary function that will be called to generate this attribute's value on demand.
void	Bind ( FGetter&& InGetter )	Binds an arbitrary function that will be called to generate this attribute's value on demand.
void	Bind ( TSharedRef< SourceType > InUserObje..., typename FGetter::template TSPMetho... )	Binds an arbitrary function that will be called to generate this attribute's value on demand.
void	BindRaw ( SourceType* InUserObject, typename FGetter::template TRawMeth... )	Binds an arbitrary function that will be called to generate this attribute's value on demand.

void	BindUObject ( SourceType* InUserObject, typename FGetter::template TUObject... )	Binds an arbitrary function that will be called to generate this attribute's value on demand.
TAttribute< ...	Create ( SourceType* InUserObject, const FName& InFunctionName )	Creates an attribute by binding an arbitrary function that will be called to generate this attribute's value on demand.
TAttribute< ...	Create ( TFunction< ObjectType(void)>&& InL... )
TAttribute	Create ( typename FGetter::FStaticDelegate::... )	Creates an attribute by binding an arbitrary function that will be called to generate this attribute's value on demand.
TAttribute	Create ( const FGetter& InGetter )	Static: Creates an attribute that's pre-bound to the specified 'getter' delegate
const Object...	Get()	Gets the attribute's current value. Assumes that the attribute is set.
const Object...	Get ( const ObjectType& DefaultValue )	Gets the attribute's current value.
const FGette...	GetBinding()	Gets the attribute's 'getter' which can be bound or unbound
bool	IdenticalTo ( const TAttribute& InOther )	Is this attribute identical to another TAttribute.
bool	IsBound()	Checks to see if this attribute has a 'getter' function bound
bool	IsSet()	Was this TAttribute ever assigned?
void	Set ( const OtherType& InNewValue )	Sets the attribute's value
void	Set ( ObjectType&& InNewValue )	Sets the attribute's value
