return String.valueOf(number);

Specified by:

getFieldName in interface Schema<Object>

getFieldNumber

public int getFieldNumber(String name)

Description copied from interface: Schema

Gets the field number associated with the name. This is particularly useful when serializing to different formats (Eg. JSON). When using numeric field names:

return Integer.parseInt(name);

Specified by:

getFieldNumber in interface Schema<Object>

isInitialized

Description copied from interface: Schema

Returns true if there is no required field or if all the required fields are set.

Specified by:

isInitialized in interface Schema<Object>

messageFullName

public String messageFullName()
