             Summary: Add method getSize() to DurableArray
                 Key: MNEMONIC-457
                 URL: https://issues.apache.org/jira/browse/MNEMONIC-457
             Project: Mnemonic
          Issue Type: Improvement
    Affects Versions: 0.11.0
            Reporter: Tao Jie
            Assignee: Yanping Wang


Now in DurableArray, field arraySize is not public to users. It might useful if 
we have a {{getSize}} method to get the length of the DurableArray.
Also if we have method like {{System.arraycopy}} for DurableArray, it would be 
helpful in case of resizing a DurableArray.
