Constructor & Destructor Documentation

FDelegateHandle() [1/2]

FDelegateHandle::FDelegateHandle ( )

inline

Creates an initially unset handle

FDelegateHandle() [2/2]

Member Function Documentation

IsValid()

bool FDelegateHandle::IsValid ( ) const

inline

Returns true if this was ever bound to a delegate, but you need to check with the owning delegate to confirm it is still valid

operator!=()

bool FDelegateHandle::operator!= ( const FDelegateHandle &  Rhs ) const

inline

operator==()

bool FDelegateHandle::operator== ( const FDelegateHandle &  Rhs ) const

inline

Reset()

void FDelegateHandle::Reset ( )

inline

Clear handle to indicate it is no longer bound
