onFetch

protected abstract rx.Observable<Pair<P,java.util.Collection<E>>> onFetch(P page)

Implement this method to fetch ViewModels at page

refreshing

public final IProperty<java.lang.Boolean> refreshing()

Specified by:

refreshing in interface IFetchedArrayViewModel<E extends IViewModel,P,java.lang.Void,java.util.Collection<E extends IViewModel>>

Returns:

Whether the receiver is refreshing.

getNextPage

public P getNextPage()

Specified by:

getNextPage in interface IFetchedArrayViewModel<E extends IViewModel,P,java.lang.Void,java.util.Collection<E extends IViewModel>>

Returns:

An object representing next page.

setNextPage

protected void setNextPage(P nextPage)

fetchingNextPage

public final IProperty<java.lang.Boolean> fetchingNextPage()

Specified by:

fetchingNextPage in interface IFetchedArrayViewModel<E extends IViewModel,P,java.lang.Void,java.util.Collection<E extends IViewModel>>

Returns:

Whether the receiver is fetching next page.

hasNextPage

public final IProperty<java.lang.Boolean> hasNextPage()

Specified by:

hasNextPage in interface IFetchedArrayViewModel<E extends IViewModel,P,java.lang.Void,java.util.Collection<E extends IViewModel>>

Returns:

Next Page

getRefreshCommand

public final ICommand<java.lang.Void,java.util.Collection<E>> getRefreshCommand()

Specified by:

getRefreshCommand in interface IFetchedArrayViewModel<E extends IViewModel,P,java.lang.Void,java.util.Collection<E extends IViewModel>>

Returns:

Command which refreshes ViewModels.

getFetchCommand

public final ICommand<java.lang.Void,java.util.Collection<E>> getFetchCommand()

Specified by:

getFetchCommand in interface IFetchedArrayViewModel<E extends IViewModel,P,java.lang.Void,java.util.Collection<E extends IViewModel>>

Returns:

Command which fetches ViewModels. If nextPage is null, this command will refresh, else this command should fetch next page.

getFetchIfNeededCommand

public final ICommand<java.lang.Void,java.util.Collection<E>> getFetchIfNeededCommand()

Specified by:

getFetchIfNeededCommand in interface IFetchedArrayViewModel<E extends IViewModel,P,java.lang.Void,java.util.Collection<E extends IViewModel>>

Returns:

Applies IFetchedArrayViewModel.getFetchCommand() only if next page is non null or returns Observable.empty()

createRefreshCommand

protected ICommand<java.lang.Void,java.util.Collection<E>> createRefreshCommand()

createFetchCommand

protected ICommand<java.lang.Void,java.util.Collection<E>> createFetchCommand()

createFetchIfNeededCommand
