  • Method Details

    • store

      <T> void store(T o, String collection, AsyncOperationCallback<T> callback)
      Stores the object, should be an entity
      Parameters:
      o - - entity

      <T> void insert(T o, String collection, AsyncOperationCallback<T> callback)

    • store

      <T> void store(List<T> lst, AsyncOperationCallback<T> callback)
      stores the given list of objects, should be entities or embedded.
      Parameters:
      lst - - to store

    • insert

      <T> void insert(List<T> o, AsyncOperationCallback<T> callback)

    • store

      <T> void store(List<T> lst, String collectionName, AsyncOperationCallback<T> callback)

    • insert

      <T> void insert(List<T> lst, String collectionName, AsyncOperationCallback<T> callback)

    • updateUsingFields

      <T> void updateUsingFields(T ent, String collection, AsyncOperationCallback<T> callback, String... fields)
      update an object using fields specified
      Parameters:
      ent - entity
      fields - - fields

    • set

      <T> void set(T toSet, String collection, Map<String,Object> values, boolean upsert, AsyncOperationCallback<T> callback)
      changes an object in DB AND in Memory... the Object toSet WILL be modified!
      Parameters:
      toSet - entity to set values in both in mongo and in memory
      values - : contains name/values to set to the given object!

    • set

      <T> void set(Query<T> query, Map<String,Object> values, boolean insertIfNotExist, boolean multiple, AsyncOperationCallback<T> callback)
      will change an entry in mongodb-collection corresponding to given class object if query is too complex, upsert might not work! Upsert should consist of single and-queries, which will be used to generate the object to create, unless it already exists. look at Mongodb-query documentation as well
      Parameters:
      query - - query to specify which objects should be set
      values - - map fieldName->Value, which values are to be set!
      insertIfNotExist - - insert, if it does not exist (query needs to be simple!)
      multiple - - update several documents, if false, only first hit will be updated

    • inc

      <T> void inc(Query<T> query, String field, Number amount, boolean insertIfNotExist, boolean multiple, AsyncOperationCallback<T> callback)

    • inc

      <T> void inc(T toInc, String collection, String field, Number amount, AsyncOperationCallback<T> callback)
      Increases a value in an existing mongo collection entry - no reading necessary. Object is altered in place db.collection.update({"_id":toInc.id},{$inc:{field:amount}} attention: this alteres the given object toSet in a similar way
      Parameters:
      toInc - : object to set the value in (or better - the corresponding entry in mongo)
      field - : the field to change
      amount - : the value to set

    • remove

      <T> void remove(Query<T> q, AsyncOperationCallback<T> callback)

      <T> void unset(T toSet, String collection, String field, AsyncOperationCallback<T> callback)
      Un-setting a value in an existing mongo collection entry - no reading necessary. Object is altered in place db.collection.update({"_id":toSet.id},{$unset:{field:1}} attention: this alteres the given object toSet in a similar way
      Parameters:
      toSet - : object to set the value in (or better - the corresponding entry in mongo)
      field - : field to remove from document
