Class WFSLock_Impl

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

All Implemented Interfaces:

WFSLock

class WFSLock_Impl

extends java.lang.Object

implements WFSLock

The purpose of the LockFeature interface is to expose a long term feature locking mechanism to ensure consistency. The lock is considered long term because network latency would make feature locks last relatively longer than native commercial database locks.

The LockFeature interface is optional and need only be implemented if the underlying datastore supports (or can be made to support) data locking. In addition, the implementation of locking is completely opaque to the client.

Method Detail

getLockAction

public java.lang.String getLockAction()

Specify how the lock should be acquired. ALL indicates to try to get all feature locks otherwise fail. SOME indicates to try to get as many feature locks as possible. The default LOCKACTION is ALL.

Specified by:

getLockAction in interface WFSLock

setLockAction

public void setLockAction(java.lang.String lockAction)

sets

getTypeName

public java.lang.String getTypeName()

If a filter is not specified, then the optional typeName attribute can be used to specify that all feature instances of a particular feature type should be locked.

Specified by:

getTypeName in interface WFSLock

setTypeName

public void setTypeName(java.lang.String typeName)

sets

getHandle

public java.lang.String getHandle()

The handle attribute is included to allow a server to associate any text to the response. The purpose of the handle attribute is to provide an error handling mechanism for locating a statement that might fail. Or to identify an InsertResult.

Specified by:

getHandle in interface WFSLock

setHandle

public void setHandle(java.lang.String handle)

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 WFSLock

setFilter

public void setFilter(Filter filter)

sets the

getFeatureIds

public java.lang.String[] getFeatureIds()

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

Specified by:

getFeatureIds in interface WFSLock

addFeatureIds

public void addFeatureIds(java.lang.String featureIds)

adds the

setFeatureIds

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

sets the
