Return single page rows

Returns:

refresh

public void refresh()
             throws ContentProviderException

Specified by:

refresh in interface IRefreshable

Throws:

ContentProviderException - if error loading data from the data source

getNumberOfCalls

public int getNumberOfCalls()

setNumberOfCalls

public void setNumberOfCalls(int numberOfCalls)

getPropertyKeys

public Object[] getPropertyKeys()

Description copied from interface: IContentProvider

Returns list of properties supported by this content provider. Can return Object[0], never null.

Specified by:

getPropertyKeys in interface IContentProvider

Returns:

array of property keys which is typically of type String or Integer

hasProperty

public boolean hasProperty(Object propertyKey)

Description copied from interface: IContentProvider

Checks if the given property is supported by this content provider

Specified by:

hasProperty in interface IContentProvider

Parameters:

propertyKey - property key of type String or Integer

Returns:

true if property is supported

getValue

public Object getValue(Object propertyKey)
                throws ELException,
PropertyNotFoundException

Description copied from interface: IContentProvider

Returns value of the given property

Specified by:

getValue in interface IContentProvider

Parameters:

propertyKey - the property key of type String or Integer

Returns:

value of the property, can be null

Throws:

PropertyNotFoundException - if property is not supported

ELException

getType

public Class<?> getType(Object propertyKey)
                 throws PropertyNotFoundException

Description copied from interface: IContentProvider

Returns java type of the given property

Specified by:

getType in interface IContentProvider

Parameters:

propertyKey - the property key of type String or Integer

Returns:

property java Class

Throws:

PropertyNotFoundException - if property is not supported

getNeedRefresh

public boolean getNeedRefresh()

Description copied from interface: IRefreshable

Returns true when IRefreshable.isAutoRefresh() is on and the result properties need to be refreshed from the data source by executing IRefreshable.refresh() method.

Implementations may return an accurate value from this method if they can track the changes to the input parameter properties or they may require the clients to call IRefreshable.setNeedRefresh(boolean) explicitely.

Specified by:

getNeedRefresh in interface IRefreshable

Returns:

true when the output properties are not up-to-date with the current input parameters, i.e. IRefreshable.refresh() needs to be executed manually or automatically.

isAutoRefresh

public boolean isAutoRefresh()

Description copied from interface: IRefreshable

Returns true if the provider is currenlty in auto-refresh mode

Specified by:

isAutoRefresh in interface IRefreshable

Returns:

false if auto-refresh mode is off or not supported

setAutoRefresh

public void setAutoRefresh(boolean autorefresh)
                    throws ContentProviderException

Description copied from interface: IRefreshable

Sets auto refresh mode on. When auto refresh mode is on, the provider calls IRefreshable.getNeedRefresh() to determine whether the refresh needs to be done before returning any result properties. If it returns true, the provider calls IRefreshable.refresh() method to updated the result properties.

Specified by:

setAutoRefresh in interface IRefreshable

Parameters:

autorefresh - true to turn it on

Throws:

ContentProviderException - if auto refresh mode is not supported
