All Implemented Interfaces:
JoinableTable, ServerObject, HasTableBinding
@TsName(namespace="dh", name="Table") public class JsTable extends HasLifecycle implements HasTableBinding, JoinableTable, ServerObject
Provides access to data in a table. Note that several methods present their response through Promises. This allows the client to both avoid actually connecting to the server until necessary, and also will permit some changes not to inform the UI right away that they have taken place.

      Object

    • getColumns

      @JsProperty public elemental2.core.JsArray<Column> getColumns()
      The columns that are present on this table. This is always all possible columns. If you specify fewer columns in .setViewport(), you will get only those columns in your ViewportData. size is the total count of rows in the table. The size can and will change; see the sizechanged event for details. Size will be negative in exceptional cases (eg. the table is uncoalesced, see the isUncoalesced property for details).

      @JsProperty public @JsNullable JsLayoutHints getLayoutHints()

    • getSize

      @JsProperty public double getSize()
      The total count of rows in the table. If there is a viewport subscription active, this size will be updated when the subscription updates. If not, and isUncoalesced() is true, the size will be SIZE_UNCOALESCED. Otherwise, the size will be updated when the server's update graph processes changes.

      When the size changes, the EVENT_SIZECHANGED event will be fired.

      Returns:
      the size of the table, or SIZE_UNCOALESCED if there is no subscription and the table is uncoalesced.

If the table is unfiltered, this will return the same size as getSize(). If this table was uncoalesced before it was filtered, this will return SIZE_UNCOALESCED.
      Returns:
      the size of the table before filters, or SIZE_UNCOALESCED

    • getSort

      @JsProperty public elemental2.core.JsArray<Sort> getSort()
      An ordered list of Sorts to apply to the table. To update, call applySort(Sort[]). Note that this getter will return the new value immediately, even though it may take a little time to update on the server. You may listen for the sortchanged event to know when to update the UI.
      Returns:
      Sort array

    • getFilter

      @JsProperty public elemental2.core.JsArray<FilterCondition> getFilter()
      An ordered list of filter conditions to apply to the table. To update, call applyFilter(FilterCondition[]).

      Returns:
      FilterCondition array

    • applySort

      @JsMethod public elemental2.core.JsArray<Sort> applySort(Sort[] sort)
      Replace the currently set sort on this table. Returns the previously set value. Note that the sort property will immediately return the new value, but you may receive update events using the old sort before the new sort is applied, and the sortchanged event fires. Reusing existing, applied sorts may enable this to perform better on the server. The updated event will also fire, but rowadded and rowremoved will not.
      Parameters:
      sort -
      Returns:
      Sort array

    • applyFilter

      @JsMethod public elemental2.core.JsArray<FilterCondition> applyFilter(FilterCondition[] filter)
      Replace the currently set filters on the table. Returns the previously set value. Note that the filter property will immediately return the new value, but you may receive update events using the old filter before the new one is applied, and the filterchanged event fires. Reusing existing, applied filters may enable this to perform better on the server. The updated event will also fire, but rowadded and rowremoved will not.
      Parameters:
      filter -
      Returns:
      FilterCondition array

    • applyCustomColumns

      @JsMethod public elemental2.core.JsArray<CustomColumn> applyCustomColumns(elemental2.core.JsArray<JsTable.CustomColumnArgUnionType> customColumns)

      CustomColumn array

    • setViewport

      public TableViewportSubscription setViewport(double firstRow, double lastRow)
      Overload for Java (since JS just omits the optional params).

    • setViewport

      public TableViewportSubscription setViewport(double firstRow, double lastRow, elemental2.core.JsArray<Column> columns)
      Overload for Java (since JS just omits the optional param).

    • setViewport

      @JsMethod @Deprecated public TableViewportSubscription setViewport(double firstRow, double lastRow, @JsOptional @JsNullable elemental2.core.JsArray<Column> columns, @JsOptional @JsNullable Double updateIntervalMs, @JsOptional @JsNullable Boolean isReverseViewport)
      Deprecated.
      Use createViewportSubscription(Object) instead.
      If the columns parameter is not provided, all columns will be used. If the updateIntervalMs parameter is not provided, a default of one second will be used. Until this is called, no data will be available. Invoking this will result in events to be fired once data becomes available, starting with an updated event and a rowadded event per row in that range. The returned object allows the viewport to be closed when no longer needed.
      Parameters:
      firstRow -
      lastRow -
      columns -
      updateIntervalMs -
      Returns:
      TableViewportSubscription

    • getViewportData

      @JsMethod @Deprecated public elemental2.promise.Promise<@TsTypeRef(ViewportData.class) AbstractTableSubscription.UpdateEventData> getViewportData()
      Deprecated.
      use TableViewportSubscription.getViewportData() on the result from createViewportSubscription(Object) instead.
      Gets the currently visible viewport. If the current set of operations has not yet resulted in data, it will not resolve until that data is ready. If this table is closed before the promise resolves, it will be rejected - to separate the lifespan of this promise from the table itself, call TableViewportSubscription.getViewportData() on the result from setViewport(double, double).
      Returns:
      Promise of TableData

    • subscribe

      public TableSubscription subscribe(elemental2.core.JsArray<Column> columns)
      Overload for java (since js just omits the optional var)

    • subscribe

      @JsMethod @Deprecated public TableSubscription subscribe(elemental2.core.JsArray<Column> columns, @JsOptional Double updateIntervalMs)
      Deprecated.
      Use createSubscription(Object) with a DataOptions.SubscriptionOptions instead.
      Creates a subscription to the specified columns, across all rows in the table. The optional parameter updateIntervalMs may be specified to indicate how often the server should send updates, defaulting to one second if omitted. Useful for charts or taking a snapshot of the table atomically. The initial snapshot will arrive in a single event, but later changes will be sent as updates. However, this may still be very expensive to run from a browser for very large tables. Each call to subscribe creates a new subscription, which must have AbstractTableSubscription.close() called on it to stop it, and all events are fired from the TableSubscription instance.
      Parameters:
      columns -
      updateIntervalMs -
      Returns:
      TableSubscription

    • createSubscription

      @JsMethod public TableSubscription createSubscription(@TsTypeRef(SubscriptionOptions.class) @TsTypeRef(SubscriptionOptions.class) Object options)
      Creates a subscription to the specified columns, across all rows in the table. Useful for charts or taking a snapshot of the table atomically. The initial snapshot will arrive in a single event, but later changes will be sent as updates. However, this may still be very expensive to run from a browser for very large tables. Each call to createSubscription creates a new subscription, which must have AbstractTableSubscription.close() called on it to stop it and release its resources, and all events are fired from the TableSubscription instance.
      Parameters:
      options - options for the subscription; see DataOptions.SubscriptionOptions for details
      Returns:
      a new TableSubscription

    • createViewportSubscription

      Creates a viewport subscription to the specified columns, across the specified rows in the table. The returned TableViewportSubscription instance allows the viewport to be changed over time, and events are fired from it when the data changes or when a viewport change has been applied. Each call to createViewportSubscription creates a new subscription, which must have TableViewportSubscription.close() called on it to stop it and release its resources
      Parameters:
      options - options for the viewport subscription; see DataOptions.ViewportSubscriptionOptions for details
      Returns:
      a new TableViewportSubscription

      Get a downsampled version of the table. Currently only supports downsampling with an Instant or long xCol.
      Parameters:
      zoomRange - The visible range as [start, end] or null to always use all data.
      pixelCount - The width of the visible area in pixels.
      xCol - The name of the X column to downsample. Must be an Instant or long.

    • isClosed

      @JsProperty(name="isClosed") public boolean isClosed()
      true if this table has been closed.
      Returns:
      boolean

    • isRefreshing

      @JsProperty(name="isRefreshing") public boolean isRefreshing()
      true if this table may receive updates from the server, including size changed events, updated events after initial snapshot.
      Returns:
      boolean

    • isUncoalesced

      @JsProperty(name="isUncoalesced") public boolean isUncoalesced()
      Read-only. true if this table is uncoalesced, indicating that work must be done before the table can be used.

      Uncoalesced tables are expensive to operate on - filter to a single partition or range of partitions before subscribing to access only the desired data efficiently. A subscription can be specified without a filter, but this can be very expensive. To see which partitions are available, check each column on the table to see which have Column.getIsPartitionColumn() as true, and filter those columns. To read the possible values for those columns, use selectDistinct(Column[]).

      Returns:
      true if the table is uncoaleced and should be filtered before operating on it, otherwise false.
