Method Detail

requestRows

public com.google.gwt.gen2.table.client.TableModelHelper.SerializableResponse<ViewClassificationNode> requestRows(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 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.
