Constructor Detail

AggregateConvexHullRequest

public AggregateConvexHullRequest()

Constructs an AggregateConvexHullRequest object with default parameters.

AggregateConvexHullRequest

public AggregateConvexHullRequest(String tableName,
                          String xColumnName,
                          String yColumnName,
                          Map<String,String> options)

Constructs an AggregateConvexHullRequest object with the specified parameters.

Parameters:

tableName - Name of Table on which the operation will be performed. Must be an existing table. It can not be a collection.

xColumnName - Name of the column containing the x coordinates of the points for the operation being performed.

yColumnName - Name of the column containing the y coordinates of the points for the operation being performed.

options - Optional parameters.
