Method Detail

getFeature

java.util.List<Feature> getFeature(java.lang.String datasourceName,
                                 java.lang.String datasetName,
                                 Rectangle2D bounds,
                                 java.lang.String attributeFilter,
                                 java.lang.String[] fields,
                                 PrjCoordSys targetPrj)

Get the elements within the specified space and meet certain attribute filters.

Parameters:

datasourceName - the name of the datasource.

datasetName - the dataset name.

bounds - The specified query range.

attributeFilter - Attribute query filter. Such as fieldValue <100, name like '% hotel%'

fields - An array of fields to be returned. When the parameter is null, all fields are returned.

targetPrj - The coordinate system of the geometric object in the feature returned

Returns:

Feature lists.

getFeature

java.util.List<Feature> getFeature(java.lang.String datasourceName,

                                 PrjCoordSys targetPrj)

Gets the elements through SQL query criteria.

Parameters:

datasourceName - the name of the datasource.

queryParam - Query parameters.

maxFeatures - The maximum number of elements that can be returned.

targetPrj - The coordinate system of the geometric object in the feature returned

Returns:

Feature lists.

Gets a feature that has a specific spatial query pattern consistent with the specified geometric object and satisfies the specified attribute filter, and supports dynamic projection to the returned geometry.

Parameters:

datasourceName - the name of the datasource.

datasetName - the dataset name.

geometry - Geometric object.

spatialQueryMode - spatial query mode.

attributeFilter - Filter condition of attribute quering Such as fieldValue <100, name like '% hotel%'

fields - An array of fields to be returned. When the parameter is null, all fields are returned.

targetPrj - The array of fields to be returned. All the fields are returned if this parameter is null.

Returns:

feature list.
