Enum Constant Details

LAZY

public static final ListGridFetchType LAZY

Lazy fetch

This is the default data fetch for the ListGrid. The lazy fetch type does not fetch all records from the list grid’s specified DataDescriptor, but only a part of it. The number of concurrent records to be fetched is set using the JBStrap parameter JBStrapParamType.PAGE_SIZE. The default value for this parameter is 50 records. If the user scrolls down to the bottom of the grid, the next page is automatically fetched from the database and appends it to the previous one, displaying two pages. This way of working ensures a low level of data transfer between the server and the client computer. It accelerates data retrieval and visualization, thereby making the user wait less to see the data.

FULL

public static final ListGridFetchType FULL

Fetch all data

This solution fetches all data from the database and displays it on the interface. It is only advisable to use this solution if you expect only a small amount of data is to be displayed. If the DataDescriptor contains a large amount of data, this causes a long waiting time for the user to fetch/visualize the data. This is a possible performance problem for the user.
