Switched back to the old style of rendering (as in 1.4.x) of DBObjects when they are used as values in persistent domain objects, adjusted the GeoConverters accordingly. In order to render geo structures correctly when they are used within a query we now wrap them in a GeoCommand that triggers a different Shape rendering.
We now render the metric that was used in the Distance definition of the radius of a Circle or Sphere.
Moved to use the newly introduced geo types from Spring Data Commons. Adde deprecation warning suppression everywhere else.
Adapted Sonargraph architecture description file and split up namespace registration into repository specific stuff and everything else.
Backed the geo spatial structures of SD MongoDB by the new geo spatial structures in SD commons. Deprecated the MongoDB geo spatial types to make users aware that we're going to remove them in one of the following development iterations. Added custom conversions for basic geo spatial types.
We deliberately choose not to let Circle extends CMNS geo.Circle since it would break clients that use the legacy Circle API (getRadius() returns a Distance in CMNS where as it returns a plain double in Mongo).
Took the change to add @since tags to the types introduced for lazy loading. Polished JavaDoc where necessary. Removed methods solely existing for testing purposes and use reflection in tests to minimize the API being published.
Added LazyLoadingProxy interface that will be implemented by every LazyLoading-proxy that is created by the DefaultDbRefResolver. Clients can now cast those proxies to this interface and call it's methods initialize a proxy explicitly or to get the referenced DBRef if possible.
We now keep a reference to the DBRef that lead to the creation of a LazyLoadingProxy in order to be able to reuse it in case one assigns the proxy to a field that should be a DBRef. This avoids unnecessary conversion.
Previously saving of proxies wasn't possible since the mapping infrastructure did not know how to extract the entity information from the proxy. We now either store the DBRef backed by the proxy directly or we initialize the proxy first and use the result of LazyLoadingProxy.initialize().

User provided converters are now registered *after* the default converters to make sure they enjoy precedence over the default ones.
This is achieved by inverting the order of converters after the conversions have been registered. This is necessary as the registration order for convertible pairs is different from the one of the converters. For the pairs, earlier registered instances take precedence, while for the actual converter instances, instances registered later trump ones registered before.
Inlined a few methods to reduce the number of indirections. Added a bit of missing JavaDoc here and there. StringBasedMongoQuery now prevents a manually defined query from being marked as both count and delete query.
Polished test cases a little.
Original pull request: #147.
Using keywords remove or delete in derived query, or setting @Query(delete=true) removes documents matching the query. If the return type is assignable to Number, the total number of affected documents is returned. In case the return type is collection like the query is executed against the store in first place. All documents included in the resulting collection are deleted in a subsequent call.
Additionally findAllAndRemove(…) methods have been added to MongoTemplate.
Original pull request: #147.
AbstractMappingConfiguration.getMappingBasePackage() now quards against a null package returned for the configuration class. This can happen if the class resides in the default package.
Adapted usage of BeanWrapper as the property access is now solely defined via the PersistentProperty. Adapted MongoPersistentEntityIndexCreator to lookup annotations via PersistentProperty instead of the backing field. Removed code from BasicMongoPersistentProperty which is now already implemented in the Spring Data Commons types.
UpdateMapper now only performs simple conversion if it encounters a DBObject, instead of deep inspection on keywords used. This allows to use custom clauses nested in Update for operations not directly supported.
Original Pull Request: #138.
Query Mapper skips DBRef conversion in case the given source value is a nested DBObject. This allows to directly use mongodb operators wrapped in DBObject on association properties.
Original Pull Request: #139.
Repositories now declare a fallback MappingContext in case none is configured explicitly to make sure @EnableMongoAuditing also works without an explicit MappingContext bean defined.
AuditingEntityListener is now referring to the IsNewAwareAuditingHandler via an intermediate ObjectFactory to prevent the downstream dependencies from being instantiated eagerly at listener init time.
This is to prevent circular initialization dependencies as Spring accesses ApplicationEventListener beans very early in the container lifecycle to check whether they might be interested in a certain even and just dropped immediately afterwards.
Changed BeanNames.MAPPING_CONTEXT constant to mongoMappingContext to let the XML configuration be consistent with AbstractMongoConfiguration.mongoMappingContext().
Changed AbstractMongoQuery to potentially convert all query execution results using the DefaultConversionService in case the query result doesn't match the expected return value.
This allows arrays to be returned for collection queries as the conversion service cam transparently convert between collections and arrays.
Added support for Slice as return type for query methods. The execution will expand the requested page size by one to read one more element than actually requested. If that additional element is returned, it will considered to be an indicator for whether a next slice is available.
Related issues: DATACMNS-397.
NearQuery now ignores query.getLimit() equal to zero, when adding Query to NearQuery. This has to be done as limit is defaulted to zero within Query which then results in unintended propagation of the parameter.
In case 'num' should be explicitly set to zero one might use 'NearQuery.num(0)' as an alternative to the query approach.
Introduced 'null' check for 'NearQuery.query(Query)' and 'NearQuery.with(Pageable)' along the way.

Switched to use Spring Data Commons' CollectionFactory that is capable of creating EnumSets and EnumMaps. Added unit test inspired by pull request #113 for EnumSets and an additional one for EnumMaps.
Slightly refactored the algorithm for reading maps to prevent repeated type lookups.

Update artifact version in readme for release and snapshot.
Use commons 1.7.0 resources in docbkx.
Update changelog.
Update version information in notice and readme.
Original pull request: #130.
Update holds a set of fields that modifications are registered for. This information is used to determine if a modification is registered for the version field of a versioned entity. The change was introduced since the present solution did not correctly find the version property correctly within the DBObject resulting from the mapped update.
In case version property is already included in Update automatic version update via $inc is will be skipped.
Original pull request: #126
Refactored the internals of UpdateMapper to simplify the code a little. Removed the special converter in favor of handling the mapped key generation directly. This can be removed again, once DATACMNS-444 is fixed.
MetadataBackedField.getPath(String) now also rejects PersistentPropertyPaths the refer to anything else but the id property in case it traverses an association.
Changed MetadataBackedField to return the association property in calls to ….getProperty() as it is the PersistentProperty to hand to the mapping infrastructure for object conversion.
Changed MappingMongoConverter to also check, whether the given source object handed into DBRef creation is of the ID type and simply use that for DBRef creation. This allows creating DBRefs from ids as well.
We now support pointing to DBRef-mapped properties in Update.pull(…) and also allow to refer to the id of the DBRef to avoid having to create an instance of the entity.
Added build profile to be able to build against next Mongo Java driver version (2.12.0-rc0) currently. Tweaked Bundlor version replacements to allow binding non-OSGi compatible Mongo driver versions.
Exception translator now handles newly introduced MongoServerSelectionException which the driver throws to indicate it can't connect to a MongoDB instance as of driver version 2.12. GridFsTemplate now uses an empty query object instead of null to indicate that no query should be used.
Adapted test cases to be able to deal with the slightly changed representation of serverUsed in command results (2.12 removed leading slash).
Added inspection of the query object to check if the update should only apply to a given version. If so and no documents have been updated we still throw an OptimisticLockingException. For all other cases - like UpdateFirst - zero affected documents is fine.
Original Pull Request: #121.
Changed convertToMongoType(…) to forward type hints to recursive calls to make sure type information is written if a TypeInformation was provided initially. Make sure that UpdateMapper hands in an initial type hint to the converter to make sure type information gets written.
Changed the signature of QueryMapper.getMappedObjectForField(…) to allow customizing the entire entry being added to the result. This is in preparation of more advanced mappings that might have to customize the mapped key.
Fixed newly introduced test cases in MongoTemplateTests.

$pushAll has been deprecated in MongoDB 2.4. Instead of calling pushAll one can use push in combination with each. The abstraction for pushAll will remain in code for now but may be removed in a subsequent version.
Original pull request: #112.
We now use a ConcurrentHashMap to cache the results of custom read target lookups in order to avoid having to traverse the readingPairs for every lookup. The use of ConcurrentHashMap should also prevent potentially NullPointerExceptions from being thrown if custom conversions are initialized in heavily threaded environments.
Original pull request: #117.
We now correctly add a compound expression that represents a field reference to the previous operation arguments if necessary.
Original pull request: #118.
Previously we didn't set a proper target value for the generated expression field. As a potential fix we just use the alias as the target field.
Original pull request: #116.
