Constructor Details

BaseGridAttributes

protected BaseGridAttributes(@Nullable
 @Nullable Map<String,Object> initialAttributes)

Parameters:

initialAttributes - The attributes map to use until mutated, or else null to allocate a new one

Method Details

restrictSortTo

@ConcurrentMethod
public final IFACE_TYPE restrictSortTo(@NotNull
 @NotNull String... allowedSortingColumns)

Description copied from interface: GridAttributes

Disallow sorting on all but the specified columns.

Specified by:

restrictSortTo in interface GridAttributes<IFACE_TYPE extends GridAttributes<IFACE_TYPE>>

Parameters:

allowedSortingColumns - The columns for which sorting is to be allowed

Returns:

A copy of this grid with the sort restrictions applied, or this if no change was needed

getSortableColumns

public Set<String> getSortableColumns()

setSortableColumns

protected void setSortableColumns(@NotNull
 @NotNull Collection<String> allowedSortingColumns)

clearSortingRestrictions

@ConcurrentMethod
public final IFACE_TYPE clearSortingRestrictions()

Description copied from interface: GridAttributes

Clear all sorting restrictions that were applied to the grid.

Specified by:

clearSortingRestrictions in interface GridAttributes<IFACE_TYPE extends GridAttributes<IFACE_TYPE>>

Returns:

A copy of this grid with the sort restrictions removed, or this if no change was needed

withDescription

@ConcurrentMethod
public final IFACE_TYPE withDescription(@NotNull
 @NotNull String description)

Description copied from interface: GridAttributes

withColumnDescription

@ConcurrentMethod
public final IFACE_TYPE withColumnDescription(@NotNull
 @NotNull String column,
 @NotNull
 @NotNull String description)

Description copied from interface: GridAttributes

Add a description for a specific column. Users should use GridAttributes.withColumnDescriptions(Map) to set several descriptions at once.

Specified by:

withColumnDescription in interface GridAttributes<IFACE_TYPE extends GridAttributes<IFACE_TYPE>>

Parameters:

column - The name of the column
