DatasetBufferAnalystParameters.js, line 7
Name Type Description
options Object

The parameters.

Name Type Default Description
dataset string

The name of the dataset in the datasource for buffer analysis. This identifier is the format "dataset name@datasource alias".
filterQueryParameter SuperMap.FilterParameter optional

Sets the filter condition for the geometric objects in the dataset. Only the geometric objects that meet this condition will participate in the buffer analysis.
resultSetting SuperMap.DataReturnOption optional

The DataReturnOption class.
isAttributeRetained boolean true optional

Whether to retain the field attribute of the object for buffer analysis. When the isUnion field is false, it is valid
isUnion boolean false optional

Whether to unite the buffer and the object in the source recordset and then return them. For the region object, it is required that the region object in the source dataset is not allowed to intersect.
bufferSetting SuperMap.BufferSetting optional

Sets the general buffer parameters.
