Class WFSQuery_Impl

java.lang.Object
  org.deegree_impl.services.wfs.protocol.WFSQuery_Impl

All Implemented Interfaces:

WFSQuery

Direct Known Subclasses:

CASQuery_Impl

public class WFSQuery_Impl

extends java.lang.Object

implements WFSQuery

Each individual query packaged in a GetFeature request is defined using the query value. The query value defines which feature type to query, what properties to retrieve and what constraints (spatial and non-spatial) to apply to those properties.

Method Detail

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.

Specified by:

getPropertyNames in interface WFSQuery

addPropertyNames

public void addPropertyNames(java.lang.String propertyNames)

adds the

setPropertyNames

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

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 WFSQuery

setHandle

public void setHandle(java.lang.String handle)

sets the

getVersion

public java.lang.String getVersion()

The version attribute is included in order to accommodate systems that support feature versioning. A value of ALL indicates that all versions of a feature should be fetched. Otherwise an integer can be specified to return the n th version of a feature. The version numbers start at '1' which is the oldest version. If a version value larger than the largest version is specified then the latest version is return. The default action shall be for the query to return the latest version. Systems that do not support versioning can ignore the parameter and return the only version that they have.

Specified by:

getVersion in interface WFSQuery

setVersion

public void setVersion(java.lang.String version)

sets the

getTypeName

public java.lang.String getTypeName()

The typeName attribute is used to indicate the name of the feature type or class to be queried.

Specified by:

getTypeName in interface WFSQuery

setTypeName

public void setTypeName(java.lang.String typeName)

sets the

getFilter

public Filter getFilter()

returns the filter that limits the query

Specified by:

getFilter in interface WFSQuery

setFilter

public void setFilter(Filter filter)

sets the filter that limits the query

exportAsXML

public java.lang.String exportAsXML()

exports the WFSQuery as XML expression

Specified by:
