Detailed Description

template<typename ItemType>
class TDelegateFilter< ItemType >

A generic filter designed to call a predicate provided on construction to filter

Constructor & Destructor Documentation

◆ TDelegateFilter()

template<typename ItemType >
TDelegateFilter< ItemType >::TDelegateFilter ( FPredicate  InPredicate)
inline

TDelegateFilter Constructor

Parameters
InPredicateA required delegate called to determine if an Item passes the filter

Member Function Documentation

◆ BroadcastChanged()

template<typename ItemType >
void TDelegateFilter< ItemType >::BroadcastChanged ( )
inline

Broadcasts the OnChanged event for this filter

◆ DECLARE_DELEGATE_RetVal_OneParam()

template<typename ItemType >
TDelegateFilter< ItemType >::DECLARE_DELEGATE_RetVal_OneParam ( bool  ,
FPredicate  ,
ItemType   
)

◆ DECLARE_DERIVED_EVENT()

template<typename ItemType >
TDelegateFilter< ItemType >::DECLARE_DERIVED_EVENT ( TDelegateFilter< ItemType >  ,
IFilter< ItemType >::FChangedEvent  ,
FChangedEvent   
)

◆ OnChanged()

template<typename ItemType >
virtual FChangedEvent & TDelegateFilter< ItemType >::OnChanged ( )
inlineoverridevirtual

Implements IFilter< ItemType >.

◆ PassesFilter()

template<typename ItemType >
virtual bool TDelegateFilter< ItemType >::PassesFilter ( ItemType  InItem) const
inlineoverridevirtual

Returns whether the specified Item passes the Filter's restrictions

Parameters
InItemThe Item is check
Returns
Whether the specified Item passed the filter

Implements IFilter< ItemType >.
