org.geotools.data
Class DefaultRepository

java.lang.Object
  org.geotools.data.DefaultRepository

All Implemented Interfaces:

Repository

public class DefaultRepository

extends java.lang.Object

implements Repository

Quick hack of a DataRepository allows me to bridge the existing DataStore API with these experiments for a Opperations api. I have used the old DefaultCatalaog as a starting point. This also serves as a reminder that we need CrossDataStore functionality - at least for Locks. And possibly for "Query".

Method Detail

load

public void load(java.io.File propertiesFile)
          throws java.lang.Exception

Load a quick datastore definition from a properties file.

This is useful for test cases.

Throws:

java.io.IOException

java.io.FileNotFoundException

java.lang.Exception

getFeatureSources

public java.util.SortedMap getFeatureSources()

Description copied from interface: Repository

All FeatureSources by typeRef ( aka dataStoreId:typeName)

Specified by:

getFeatureSources in interface Repository

getPrefixes

public java.util.Set getPrefixes()
                          throws java.io.IOException

Retrieve prefix set.

Specified by:

getPrefixes in interface Repository

Returns:

Set of namespace prefixes

Throws:

java.io.IOException

See Also:

org.geotools.data.Catalog#getPrefixes()

types

public java.util.SortedMap types()
                          throws java.io.IOException

All FeatureTypes by dataStoreId:typeName

Throws:

java.io.IOException

lockExists

public boolean lockExists(java.lang.String lockID)

Implement lockExists.

Specified by:

lockExists in interface Repository

Parameters:

lockID -

Returns:

true if lock was found

See Also:

org.geotools.data.Catalog#lockExists(java.lang.String)

lockRefresh

public boolean lockRefresh(java.lang.String lockID,
                           Transaction transaction)
                    throws java.io.IOException

Implement lockRefresh.

Currently it is an error if the lockID is not found. Because if we can't find it we cannot refresh it.

Since locks are time sensitive it is impossible to check if a lockExists and then be sure it will still exist when you try to refresh it. Nothing we do can protect client code from this fact, they will need to do with the IOException when (not if) this situation occurs.

Specified by:

lockRefresh in interface Repository

Parameters:

lockID - Authorizataion of lock to refresh

transaction - Transaction used to authorize refresh

Returns:

true if lock was found and refreshed

Throws:

java.io.IOException - If opperation encounters problems, or lock not found

java.lang.IllegalArgumentException - if lockID is null

See Also:

org.geotools.data.Catalog#lockRefresh(java.lang.String, org.geotools.data.Transaction)

lockRelease

public boolean lockRelease(java.lang.String lockID,
                           Transaction transaction)
                    throws java.io.IOException

Implement lockRelease.

Currently it is not and error if the lockID is not found, it may have expired. Since locks are time sensitive it is impossible to check if a lockExists and then be sure it will still exist when you try to release it.

Specified by:

lockRelease in interface Repository

Parameters:

lockID - Authorizataion of lock to refresh

transaction - Transaction used to authorize refresh

Returns:

true if lock was found and released

Throws:

java.io.IOException - If opperation encounters problems

java.lang.IllegalArgumentException - if lockID is null

See Also:

org.geotools.data.Catalog#lockRefresh(java.lang.String, org.geotools.data.Transaction)

register

public void register(java.lang.String id,
