A representation of the model object 'Query Type'.
The Query element is of type QueryType.
The following features are supported:

| Method Summary | |
| String | getFeatureVersion()
Returns the value of the 'Feature Version' attribute.
For systems that implement versioning, the featureVersion
attribute is used to specify which version of a particular
feature instance is to be retrieved. | | Filter | getFilter()
Returns the value of the 'Filter' attribute.
The Filter element is used to define spatial and/or non-spatial
constraints on query. | | EList | getFunction()
Returns the value of the 'Function' attribute list. | | FeatureMap | getGroup()
Returns the value of the 'Group' attribute list. | | String | getHandle()
Returns the value of the 'Handle' attribute.
The handle attribute allows a client application
to assign a client-generated identifier for the
Query. | | EList | getPropertyName()
Returns the value of the 'Property Name' attribute.
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. | | EList | getSortBy()
Returns the value of the 'Sort By' attribute. | | URI | getSrsName()
Returns the value of the 'Srs Name' attribute.
This attribute is used to specify a specific WFS-supported SRS
that should be used for returned feature geometries. | | List | getTypeName()
Returns the value of the 'Type Name' attribute.
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. | | EList | getXlinkPropertyName()
Returns the value of the 'Xlink Property Name' containment reference list. | | void | setFeatureVersion(String value)
Sets the value of the '
net.opengis.wfs.QueryType.getFeatureVersion Feature Version ' attribute. | | void | setFilter(Filter value)
Sets the value of the '
net.opengis.wfs.QueryType.getFilter Filter ' attribute. | | void | setHandle(String value)
Sets the value of the '
net.opengis.wfs.QueryType.getHandle Handle ' attribute. | | void | setSrsName(URI value)
Sets the value of the '
net.opengis.wfs.QueryType.getSrsName Srs Name ' attribute. | | void | setTypeName(List value)
Sets the value of the '
net.opengis.wfs.QueryType.getTypeName Type Name ' attribute. |
| getFeatureVersion | | String getFeatureVersion()(Code) | | Returns the value of the 'Feature Version' attribute.
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.
the value of the 'Feature Version' attribute.

| getFilter | | Filter getFilter()(Code) | | Returns the value of the 'Filter' attribute.
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.
the value of the 'Filter' attribute.

See Also: net.opengis.wfs.WFSPackage.getQueryType_Filter |
| getFunction | | EList getFunction()(Code) | | Returns the value of the 'Function' attribute list.
The list contents are of type
java.lang.Object .
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
the value of the 'Function' attribute list.

| getGroup | | FeatureMap getGroup()(Code) | | Returns the value of the 'Group' attribute list.
The list contents are of type
org.eclipse.emf.ecore.util.FeatureMap.Entry .
If the meaning of the 'Group' attribute list isn't clear,
there really should be more of a description here...
the value of the 'Group' attribute list.
See Also: net.opengis.wfs.WfsPackage.getQueryType_Group |
| getHandle | | String getHandle()(Code) | | Returns the value of the 'Handle' attribute.
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).
the value of the 'Handle' attribute.
See Also: QueryType.setHandle(String)
See Also: net.opengis.wfs.WfsPackage.getQueryType_Handle |
| getPropertyName | | EList getPropertyName()(Code) | | Returns the value of the 'Property Name' attribute.
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.
the value of the 'Property Name' attribute.

| getSortBy | | EList getSortBy()(Code) | | Returns the value of the 'Sort By' attribute.
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.
the value of the 'Sort By' attribute.
See Also: QueryType.setSortBy(Object)
See Also: net.opengis.wfs.WFSPackage.getQueryType_SortBy |
| getSrsName | | URI getSrsName()(Code) | | Returns the value of the 'Srs Name' attribute.
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.
the value of the 'Srs Name' attribute.
See Also: QueryType.setSrsName(String)
See Also: net.opengis.wfs.WFSPackage.getQueryType_SrsName |
| getTypeName | | List getTypeName()(Code) | | Returns the value of the 'Type Name' attribute.
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.
the value of the 'Type Name' attribute.
