Method Detail

validate

public static boolean validate(Schema schema,
                               Object datum)

Returns true if an object matches a schema.

getSchema

public static Schema getSchema(Type type)

Generate a schema for a Java type.

For records, declared fields (not inherited) which are not static or transient are used.

Note that unions cannot be automatically generated by this method, since Java provides no representation for unions.

getProtocol

public static Protocol getProtocol(Class iface)

Generate a protocol for a Java interface.

Note that this requires that Paranamer is run over compiled interface declarations, since Java 6 reflection does not provide access to method parameter names. See Avro's build.xml for an example.
