java.lang.Throwable

java.lang.Exception

java.lang.RuntimeException

com.google.protobuf.UninitializedMessageException

All Implemented Interfaces:

java.io.Serializable

public class UninitializedMessageException
extends java.lang.RuntimeException

Thrown when attempting to build a protocol message that is missing required fields. This is a RuntimeException because it normally represents a programming error: it happens when some code which constructs a message fails to set all the fields. parseFrom() methods do not throw this; they throw an InvalidProtocolBufferException if required fields are missing, because it is not a programming error to receive an incomplete message. In other words, UninitializedMessageException should never be thrown by correct code, but InvalidProtocolBufferException might be.

Method Detail

getMissingFields

public java.util.List<java.lang.String> getMissingFields()

Get a list of human-readable names of required fields missing from this message. Each name is a full path to a field, e.g. "foo.bar[5].baz". Returns null if the lite runtime was used, since it lacks the ability to find missing fields.

asInvalidProtocolBufferException

public InvalidProtocolBufferException asInvalidProtocolBufferException()

Converts this exception to an InvalidProtocolBufferException. When a parsed message is missing required fields, this should be thrown instead of UninitializedMessageException.
