      Load the named table, with columns and size information already fully populated.
      Parameters:
      name - the name of the table to fetch
      applyPreviewColumns - false to disable previews, defaults to true
      Returns:
      a Promise that will resolve to the table, or reject with an error if it cannot be loaded.

      Load the named Figure, including its tables and tablemaps as needed.
      Parameters:
      name -
      Returns:
      promise of dh.plot.Figure

    • getTreeTable

      public elemental2.promise.Promise<JsTreeTable> getTreeTable(String name)
      Loads the named tree table or roll-up table, with column data populated. All nodes are collapsed by default, and size is presently not available until the viewport is first set.
      Parameters:
      name -
      Returns:

    • getHierarchicalTable

      public elemental2.promise.Promise<JsTreeTable> getHierarchicalTable(String name)

    • getPartitionedTable

      public elemental2.promise.Promise<JsPartitionedTable> getPartitionedTable(String name)

    • getObject

      public elemental2.promise.Promise<?> getObject(@TsTypeRef(JsVariableDescriptor.class) @TsTypeRef(JsVariableDescriptor.class) jsinterop.base.JsPropertyMap<Object> definitionObject)

    • newTable

      public elemental2.promise.Promise<JsTable> newTable(String[] columnNames, String[] types, String[][] data, String userTimeZone)

    • mergeTables

      public elemental2.promise.Promise<JsTable> mergeTables(JsTable[] tables)
      Merges the given tables into a single table. Assumes all tables have the same structure.
      Parameters:
      tables -
      Returns:
      Promise of JsTable

    • bindTableToVariable

      public elemental2.promise.Promise<Void> bindTableToVariable(JsTable table, String name)

    • shareObject

      public elemental2.promise.Promise<SharedExportBytesUnion> shareObject(ServerObject.Union object, SharedExportBytesUnion sharedTicketBytes)
      Makes the object available to another user or another client on this same server which knows the value of the sharedTicketBytes. Use that sharedTicketBytes value like a one-time use password - any other client which knows this value can read the same object.

      Shared objects will remain available using the sharedTicketBytes until the client that first shared them releases/closes their copy of the object. Whatever side-channel is used to share the bytes, be sure to wait until the remote end has signaled that it has successfully fetched the object before releasing it from this client.

      Be sure to use an unpredictable value for the shared ticket bytes, like a UUID or other large, random value to prevent access by unauthorized clients.

      Parameters:
      object - the object to share with another client/user
      sharedTicketBytes - the value which another client/user must know to obtain the object. It may be a unicode string (will be encoded as utf8 bytes), or a Uint8Array value.
      Returns:
      A promise that will resolve to the value passed as sharedTicketBytes when the object is ready to be read by another client, or will reject if an error occurs.

    • getSharedObject

      public elemental2.promise.Promise<?> getSharedObject(SharedExportBytesUnion sharedTicketBytes, String type)
      Reads an object shared by another client to this server with the sharedTicketBytes. Until the other client releases this object (or their session ends), the object will be available on the server.

      The type of the object must be passed so that the object can be read from the server correct - the other client should provide this information.

      Parameters:
      sharedTicketBytes - the value provided by another client/user to obtain the object. It may be a unicode string (will be encoded as utf8 bytes), or a Uint8Array value.
      type - The type of the object, so it can be correctly read from the server
      Returns:
      A promise that will resolve to the shared object, or will reject with an error if it cannot be read.
