Specified by:

store in interface MorphiumWriter

Parameters:

lst - - to store

public <T> void updateUsingFields(T ent,
                         String collection,
                         AsyncOperationCallback<T> c,
                         String... fields)

Description copied from interface: MorphiumWriter

update an object using fields specified

Specified by:

updateUsingFields in interface MorphiumWriter

Parameters:

ent - entity

fields - - fields

set

public <T> void set(T toSet,
           String collection,
           String field,
           Object value,
           boolean insertIfNotExists,
           boolean multiple,
           AsyncOperationCallback<T> c)

Description copied from interface: MorphiumWriter

changes an object in DB AND in Memory... the Object toSet WILL be modified!

Specified by:

set in interface MorphiumWriter

Parameters:

toSet - entity to set values in both in mongo and in memory

field - field

value - value to set

set

public <T> void set(Query<T> query,
           Map<String,Object> values,
           boolean insertIfNotExist,

           AsyncOperationCallback<T> c)

Description copied from interface: MorphiumWriter

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

Specified by:

set in interface MorphiumWriter

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

Description copied from interface: MorphiumWriter

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

Specified by:

inc in interface MorphiumWriter
