      org.deegree_impl.services.wfs.protocol.WFSBasicRequest_Impl
          org.deegree_impl.services.wfs.protocol.WFSGetFeatureRequest_Impl

All Implemented Interfaces:

Marshallable, OGCWebServiceRequest, WFSBasicRequest, WFSGetFeatureRequest

Direct Known Subclasses:

WFSGetFeatureWithLockRequest_Impl, WFSGGetFeatureRequest_Impl

public class WFSGetFeatureRequest_Impl

extends WFSBasicRequest_Impl

implements WFSGetFeatureRequest, Marshallable

The GetFeature interface can be used to package one or more query descriptions into a single request. The results of all queries packaged in a GetFeature request are concatenated to produce the result set.

Method Detail

getOutputFormat

public java.lang.String getOutputFormat()

The outputFormat attribute defines the format to use to generate the result set. Vendor specific formats, declared in the capabilities document are possible. The WFS-specs implies GML as default output format.

Specified by:

getOutputFormat in interface WFSGetFeatureRequest

setOutputFormat

public void setOutputFormat(java.lang.String outputFormat)

sets the

getHandle

public java.lang.String getHandle()

The handle attribute is included to allow a client to associate a mnemonic name to the request. The purpose of the handle attribute is to provide an error handling mechanism for locating a statement that might fail.

Specified by:

getHandle in interface WFSGetFeatureRequest

setHandle

public void setHandle(java.lang.String handle)

Parameters:

handle -

getQuery

public WFSQuery[] getQuery()

The query defines which feature type to query, what properties to retrieve and what constraints (spatial and non-spatial) to apply to those properties.

only used for xml-coded requests

Specified by:

getQuery in interface WFSGetFeatureRequest

addQuery

public void addQuery(WFSQuery query)

adds the

setQuery

public void setQuery(WFSQuery[] query)

sets the

getMaxFeatures

public int getMaxFeatures()

The optional maxFeatures attribute can be used to limit the number of features that a GetFeature request retrieves. Once the maxFeatures limit is reached, the result set is truncated at that point.

Specified by:

getMaxFeatures in interface WFSGetFeatureRequest

setMaxFeatures

public void setMaxFeatures(int maxFeatures)

sets the

getStartPosition

public int getStartPosition()

The startPosition parameter identifies the first result set entry to be returned specified the default is the first record

Specified by:

getStartPosition in interface WFSGetFeatureRequest

setStartPosition

public void setStartPosition(int startPosition)

sets the

getPropertyNames

public java.lang.String[] getPropertyNames()

The property names is used to enumerate the feature properties or attributes that should be selected. If no property names are specified then all properties should be fetched.

only use for name-value-pair encoded requests

Specified by:

getPropertyNames in interface WFSGetFeatureRequest

addPropertyNames

public void addPropertyNames(java.lang.String propertyNames)

adds the

setPropertyNames

public void setPropertyNames(java.lang.String[] propertyNames)

sets the

getFeatureIds

public java.lang.String[] getFeatureIds()

A list of feature identifiers upon which the specified operation shall be applied. Optional. No default.

Only used for name-value-pair encoded requests

Specified by:

getFeatureIds in interface WFSGetFeatureRequest

addFeatureIds

public void addFeatureIds(java.lang.String featureIds)

adds the

setFeatureIds

public void setFeatureIds(java.lang.String[] featureIds)

sets the

getTypeNames

public java.lang.String[] getTypeNames()

A list of feature type names to query. Optional. No default.

only used for name-value-pair encoded requests

Specified by:

getTypeNames in interface WFSGetFeatureRequest

addTypeNames

public void addTypeNames(java.lang.String TypeNames)

adds the

setTypeNames

public void setTypeNames(java.lang.String[] typeNames)

sets the

getFilter

public Filter getFilter()

A filter specification describes a set of features to operate upon. The format of the filter is defined in the OGC Filter Encoding Specification. Optional. No default. Prerequisite: TYPENAME

Specified by:

getFilter in interface WFSGetFeatureRequest

setFilter

public void setFilter(Filter filter)

sets the

exportAsXML

public java.lang.String exportAsXML()

exports the request in its XML representation

Specified by:

exportAsXML in interface Marshallable

Overrides:
