- Method Detail
  - getSerializationType
```
abstract AbstractService.SerializationType getSerializationType()
```
    Returns:
    
    The manner in which the data is serialized.
  - finagle
```
Meta.Signature finagle(Meta.Signature signature)
```
    Modifies a signature, changing the representation of numeric columns within it. This deals with the fact that JSON transmits a small long value, or a float which is a whole number, as an integer. Thus the accessors need be prepared to accept any numeric type.

    Description copied from interface: Service
    
    Sets server-level metadata for RPCs. This includes information that is static across all RPCs.
    
    Specified by:
    
    setRpcMetadata in interface Service
    
    Parameters:
    
    metadata - The server-level metadata.
