public final class MesosferData
extends java.lang.Object
```
The MesosferData is a local representation of data that can be saved and retrieved from the Mesosfer cloud.
The basic workflow for creating new data is to construct a new MesosferData by accessing createData(MesosferDataSchema) or createData(String), use setData(String, Object) to fill it with data, and then use saveAsync(SaveCallback) to persist to the cloud.
The basic workflow for accessing existing data is to use a MesosferQuery to specify which existing data to retrieve.

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`static MesosferData`	`createData(MesosferDataSchema schema)` Constructs a new `MesosferData` with no data in it.
`static MesosferData`	`createData(java.lang.String bucket)` Constructs a new `MesosferData` with no data in it.
`static MesosferData`	`createWithObjectId(java.lang.String objectId)` Creates a reference to an existing `MesosferData` for use in creating associations between `MesosferData`s.
`void`	`deleteAsync(DeleteCallback callback)` Deletes this object on the server in a background thread.
`void`	`fetchAsync(GetCallback<MesosferData> callback)` Fetches this object with the data from the server in a background thread.
`java.util.Date`	`getCreatedAt()` This reports time as the server sees it, so that if you create a `MesosferData`, then wait a while, and then call `saveAsync(SaveCallback)`, the creation time will be the time of the first `saveAsync(SaveCallback)` call rather than the time the object was created locally.
`MesosferObject`	`getData()` Gets the `MesosferObject` that already saved in `MesosferData`.
`org.json.JSONArray`	`getDataArray(java.lang.String key)` Gets the `JSONArray` value from the `getData()` given key string.

`java.util.Date`	`getUpdatedAt()` This reports time as the server sees it, so that if you make changes to a `MesosferData`, then wait a while, and then call `saveAsync(SaveCallback)`, the updated time will be the time of the `saveAsync(SaveCallback)` call rather than the time the object was changed locally.
`boolean`	`isDataAvailable()` Gets whether the `MesosferData` has been fetched.
`void`	`saveAsync(SaveCallback callback)` Saves this object with the data from the server in a background thread.
`MesosferData`	`setData(java.lang.String key, java.lang.Object value)` Add a key-value pair to this object.

  - createData
```
public static MesosferData createData(java.lang.String bucket)
```
    Constructs a new MesosferData with no data in it. A MesosferData constructed in this way will not have an objectId and will not persist to the database until saveAsync(SaveCallback) is called.
    Bucket names must be alphanumerical, and must start with a letter. It is recommended to name classes in MesosferCaseLikeThis.
    
    Parameters:
    
    bucket - the bucket name for this MesosferData

    A new instance of MesosferData
  - createData
```
public static MesosferData createData(MesosferDataSchema schema)
