Method Details

createSearchBuilder

public ObjectSearchBuilder<FileFolder> createSearchBuilder(StringList searchColumns,
 Consumer<ObjectSearchBuilder<FileFolder>> changeConsumer)

Specified by:

createSearchBuilder in interface ObjectGridData<FileFolder,Object>

createHeader

public com.vaadin.flow.component.Component createHeader()

Description copied from interface: HasColumns

You can have a "header row" (as the first row) that covers the whole grid. Typically, such a row is to show your own buttons or components to customize the grid. The default implementation returns null, and thus, no such row is created. (Please note that HasColumns.createHeaders()} is invoked before this method for adding other header rows just above the main header row. This may be used for column grouping etc.)

Specified by:

createHeader in interface HasColumns<Object>

Overrides:

createHeader in class ObjectForestBrowser<FileFolder>

Returns:

Component to be used as the "header row".

load

public void load()

Description copied from interface: ObjectLoader

Load the instances. Current filtering conditions (return value of FilterMethods.getFilterCondition()) including "load filter" if set will be applied. Also, the value returned by ObjectLoader.getAllowAny() will determine whether instanced of the subclasses to be retrieved or not. The order will be determined by the return value of ObjectLoader.getOrderBy(). If "master" is already set, "links" of the "master" will be loaded.

Specified by:

load in interface ObjectLoader<FileFolder>

getColumnCaption

public String getColumnCaption(String columnName)

Description copied from interface: HasColumns

Get the text to display in the header. This will be invoked only if HasColumns.getColumnHeaderComponent(java.lang.String) returns null.

Specified by:

getColumnCaption in interface HasColumns<Object>

Overrides:

getColumnCaption in class AbstractObjectForest<FileFolder>

Parameters:

columnName - Column name

Returns:

Text to display as a header. By default, it tries to determine this from the Application Environment.

list

public static ObjectIterator<? extends StoredObject> list(StoredObjectUtility.Link<?> link,
 StoredObject master)
