requestRows

public com.google.gwt.gen2.table.client.TableModelHelper.SerializableResponse<ViewClassificationNode> requestRows(String serverUrl,
                                                                                                         com.google.gwt.gen2.table.client.TableModelHelper.Request request,
                                                                                                         Map<String,String> filters)

Retrieve a set of classification nodes from the registry with the given request parameters.

Specified by:

requestRows in interface ClassificationNodeService

Parameters:

request - number of rows, offset and sort

filters - filter and search params

Returns:

a GWT appropriate encapsulation of classification nodes

getClassificationNodes

public com.google.gwt.gen2.table.client.TableModelHelper.SerializableResponse<ViewClassificationNode> getClassificationNodes(String serverUrl,
                                                                                                                    String guid)

Specified by:

getClassificationNodes in interface ClassificationNodeService

indexToColumnName

public static String indexToColumnName(int index)

Convert index to column name NOTE: This is a hack to deal with the fact that the request object only knows the column index of any sort. TODO: The mapping between the index and the id should be consolidated with Registry_ui which defines the columns.
