public final class HierarchicalTableView
extends LivenessArtifact

Server-side "view" object representing a client's snapshot target for HierarchicalTable data.

Instances associate two different kinds of information to fully describe the view:

• The HierarchicalTable instance
• The key Table information to be used when snapshotting the HierarchicalTable

Instances also store re-usable snapshot states across snapshot invocations.

• Serialized Form

makeFromHierarchicalTable

public static HierarchicalTableView makeFromHierarchicalTable(@NotNull
 @NotNull HierarchicalTable<?> hierarchicalTable,
 @NotNull
 @NotNull Table keyTable,
 @Nullable
 @Nullable ColumnName keyTableActionColumn)

Make a new HierarchicalTableView that will snapshot hierarchicalTable according to the expansions described by keyTable.

Parameters:

hierarchicalTable - The HierarchicalTable to snapshot

keyTable - The Table to use for expansion key data

keyTableActionColumn - The ColumnName of expansion actions, if other than expand.

Returns:

The new HierarchicalTableView, which will have a new snapshot state

makeFromHierarchicalTable

public static HierarchicalTableView makeFromHierarchicalTable(@NotNull
 @NotNull HierarchicalTable<?> hierarchicalTable)

Make a new HierarchicalTableView that will snapshot hierarchicalTable with only the root expanded.

Parameters:

hierarchicalTable - The HierarchicalTable to snapshot

Returns:

The new HierarchicalTableView, which will have a new snapshot state

makeFromExistingView

public static HierarchicalTableView makeFromExistingView(@NotNull
 @NotNull HierarchicalTableView existingView,
 @NotNull
 @NotNull Table keyTable,
 @Nullable
 @Nullable ColumnName keyTableActionColumn)

Make a new HierarchicalTableView from an existing one, which will snapshot the existing view's HierarchicalTable according to the expansions described by keyTable.

Parameters:

existingView - The existing HierarchicalTableView

keyTable - The Table to use for expansion key data

keyTableActionColumn - The ColumnName of expansion actions, if other than expand.

Returns:

The new HierarchicalTableView, which will share snapshot state with existing

makeFromExistingView

public static HierarchicalTableView makeFromExistingView(@NotNull
 @NotNull HierarchicalTableView existingView)

Make a new HierarchicalTableView from an existing one, which will snapshot the existing view's HierarchicalTable with only the root expanded.

Parameters:

existingView - The existing HierarchicalTableView

Returns:

The new HierarchicalTableView, which will share snapshot state with existing
