Reserved for internal use. Writes an entity to the specified <code>JsonGenerator</code> as an JSON resource

@param generator
The <code>JsonGenerator</code> to write the entity to.
@param entity
The instance implementing {@link TableEntity} to write to the output stream.
@param isTableEntry
A flag indicating the entity is a reference to a table at the top level of the storage service when
<code>true<code> and a reference to an entity within a table when <code>false</code>.
@param opContext
An {@link OperationContext} object used to track the execution of the operation.

@throws StorageException
if a Storage service error occurs.
@throws IOException
if an error occurs while accessing the stream.
