public class FeatureIdQuery
extends Query

A Query that selects features using a list of ids.

NOTE: Only KVP-based queries can be of this type. For XML-requests its only possible to use a filter constraint.

FeatureIdQuery

public FeatureIdQuery(java.lang.String handle,
                      TypeName[] typeNames,
                      java.lang.String[] featureIds,
                      java.lang.String featureVersion,
                      CRS srsName,
                      PropertyName[][] propertyNames,
                      XLinkPropertyName[][] xLinkPropertyNames,
                      SortProperty[] sortBy)

Creates a new FeatureIdQuery instance.

Parameters:

handle - client-generated query identifier, may be null

typeNames - requested feature types (with optional aliases), must not be null, but can be empty

featureVersion - version of the feature instances to be retrieved, may be null

srsName - WFS-supported SRS that should be used for returned feature geometries, may be null

propertyNames - properties of the features that should be retrieved, may be null

xLinkPropertyNames - properties for which the the traversal of nested XLinks is selectively requested, may be null

sortBy - properties whose values should be used to order the set of feature instances that satisfy the query, may be null

featureIds - requested feature ids, must not be null

Method Detail

getPropertyNames

public PropertyName[][] getPropertyNames()

From WFS Speification V1.1, clause 14.7.3.1: A list of properties may be specified for each feature type that is being queried. A "*" character can be used to indicate that all properties should be retrieved. There is a 1:1 mapping between each element in a FEATUREID or TYPENAME list and the PROPERTYNAME list. The absense of a value also indicates that all properties should be fetched.

Returns:

the properties of the features that should be retrieved, may be null

getXLinkPropertyNames

public XLinkPropertyName[][] getXLinkPropertyNames()

Returns the properties for which the the traversal of nested XLinks is selectively requested.

Returns:

the properties for which the the traversal of nested XLinks is selectively requested, may be null

getFeatureIds

public java.lang.String[] getFeatureIds()

Returns the requested feature ids.

Returns:

the requested feature ids, never null
