public class QueryTypeBinding extends AbstractComplexEMFBinding
Binding object for the type http://www.opengis.net/wfs:QueryType.<code> <xsd:complexType name="QueryType"> <xsd:annotation> <xsd:documentation> The Query element is of type QueryType. </xsd:documentation> </xsd:annotation> <xsd:sequence> <xsd:choice maxOccurs="unbounded" minOccurs="0"> <xsd:element ref="wfs:PropertyName"> <xsd:annotation> <xsd:documentation> The Property element is used to specify one or more properties of a feature whose values are to be retrieved by a Web Feature Service. While a Web Feature Service should endeavour to satisfy the exact request specified, in some instance this may not be possible. Specifically, a Web Feature Service must generate a valid GML3 response to a Query operation. The schema used to generate the output may include properties that are mandatory. In order that the output validates, these mandatory properties must be specified in the request. If they are not, a Web Feature Service may add them automatically to the Query before processing it. Thus a client application should, in general, be prepared to receive more properties than it requested. Of course, using the DescribeFeatureType request, a client application can determine which properties are mandatory and request them in the first place. </xsd:documentation> </xsd:annotation> </xsd:element> <xsd:element ref="wfs:XlinkPropertyName"/> <xsd:element ref="ogc:Function"> <xsd:annotation> <xsd:documentation> A function may be used as a select item in a query. However, if a function is used, care must be taken to ensure that the result type matches the type in the </xsd:documentation> </xsd:annotation> </xsd:element> </xsd:choice> <xsd:element maxOccurs="1" minOccurs="0" ref="ogc:Filter"> <xsd:annotation> <xsd:documentation> The Filter element is used to define spatial and/or non-spatial constraints on query. Spatial constrains use GML3 to specify the constraining geometry. A full description of the Filter element can be found in the Filter Encoding Implementation Specification. </xsd:documentation> </xsd:annotation> </xsd:element> <xsd:element maxOccurs="1" minOccurs="0" ref="ogc:SortBy"> <xsd:annotation> <xsd:documentation> The SortBy element is used specify property names whose values should be used to order (upon presentation) the set of feature instances that satisfy the query. </xsd:documentation> </xsd:annotation> </xsd:element> </xsd:sequence> <xsd:attribute name="handle" type="xsd:string" use="optional"> <xsd:annotation> <xsd:documentation> The handle attribute allows a client application to assign a client-generated identifier for the Query. The handle is included to facilitate error reporting. If one Query in a GetFeature request causes an exception, a WFS may report the handle to indicate which query element failed. If the a handle is not present, the WFS may use other means to localize the error (e.g. line numbers). </xsd:documentation> </xsd:annotation> </xsd:attribute> <xsd:attribute name="typeName" type="wfs:TypeNameListType" use="required"> <xsd:annotation> <xsd:documentation> The typeName attribute is a list of one or more feature type names that indicate which types of feature instances should be included in the reponse set. Specifying more than one typename indicates that a join operation is being performed. All the names in the typeName list must be valid types that belong to this query's feature content as defined by the GML Application Schema. </xsd:documentation> </xsd:annotation> </xsd:attribute> <xsd:attribute name="featureVersion" type="xsd:string" use="optional"> <xsd:annotation> <xsd:documentation> For systems that implement versioning, the featureVersion attribute is used to specify which version of a particular feature instance is to be retrieved. A value of ALL means that all versions should be retrieved. An integer value 'i', means that the ith version should be retrieve if it exists or the most recent version otherwise. </xsd:documentation> </xsd:annotation> </xsd:attribute> <xsd:attribute name="srsName" type="xsd:anyURI" use="optional"> <xsd:annotation> <xsd:documentation> This attribute is used to specify a specific WFS-supported SRS that should be used for returned feature geometries. The value may be the WFS StorageSRS value, DefaultRetrievalSRS value, or one of AdditionalSRS values. If no srsName value is supplied, then the features will be returned using either the DefaultRetrievalSRS, if specified, and StorageSRS otherwise. For feature types with no spatial properties, this attribute must not be specified or ignored if it is specified. </xsd:documentation> </xsd:annotation> </xsd:attribute> </xsd:complexType> </code>

Method Detail
-
getTarget
public QName getTarget()
- Returns:
- The qualified name of the target for the binding.
-
getProperty
public Object getProperty(Object object, QName name) throws Exception
Overrides to return the value of the "typeName" attribute as a single String instead of a List. Otherwise typeName gets encoded as theQueryType.getTypeName()
toString's value which depends on the toString implementation of the internal java.util.List.Also, if the requested property is "SortBy" and the QueryType has an empty sortby list, returns null to avoid encoding an empty sortBy list
- Specified by:
getProperty
in interfaceComplexBinding
- Overrides:
getProperty
in classAbstractComplexEMFBinding
- Parameters:
object
- The object being encoded.name
- The name of the property to obtain.- Returns:
- The value of the property, or
null
. - Throws:
Exception
- See Also:
ComplexBinding.getProperty(Object, QName)

setProperty
protected void setProperty(EObject eObject, String property, Object value, boolean lax)
Description copied from class:AbstractComplexEMFBinding
