Class FilterByBoxRequest

java.lang.Object

com.gpudb.protocol.FilterByBoxRequest

All Implemented Interfaces:

org.apache.avro.generic.GenericContainer, org.apache.avro.generic.IndexedRecord

public class FilterByBoxRequest
extends Object
implements org.apache.avro.generic.IndexedRecord

A set of parameters for GPUdb.filterByBox(FilterByBoxRequest).

Calculates how many objects within the given table lie in a rectangular box. The operation is synchronous, meaning that a response will not be returned until all the objects are fully available. The response payload provides the count of the resulting set. A new resultant set which satisfies the input NAI restriction specification is also created when a viewName is passed in as part of the input payload.

Constructor Detail

FilterByBoxRequest

public FilterByBoxRequest()

Constructs a FilterByBoxRequest object with default parameters.

FilterByBoxRequest

public FilterByBoxRequest(String tableName,
                          String viewName,
                          String xColumnName,
                          double minX,
                          double maxX,

                          double maxY,
                          Map<String,String> options)

Constructs a FilterByBoxRequest object with the specified parameters.

Parameters:

tableName - Name of the table on which the bounding box operation will be performed. Must be an existing table.

viewName - Optional name of the result view that will be created containing the results of the query. Has the same naming restrictions as tables. The default value is ''.

xColumnName - Name of the column on which to perform the bounding box query. Must be a valid numeric column.

minX - Lower bound for the column chosen by xColumnName. Must be less than or equal to maxX.

maxX - Upper bound for xColumnName. Must be greater than or equal to minX.

yColumnName - Name of a column on which to perform the bounding box query. Must be a valid numeric column.

minY - Lower bound for yColumnName. Must be less than or equal to maxY.

maxY - Upper bound for yColumnName. Must be greater than or equal to minY.

options - Optional parameters.

• COLLECTION_NAME: Name of a collection which is to contain the newly created view. If the collection provided is non-existent, the collection will be automatically created. If empty, then the newly created view will be top-level.

The default value is an empty Map.
