Method Detail

toDebugString

@Nonnull
public static <Message extends PMessage<Message>> java.lang.String toDebugString(PMessageOrBuilder<Message> message)

Prints a pretty formatted string that is optimized for diffing (mainly for testing and debugging).

Type Parameters:

Message - The message type.

Parameters:

message - The message to stringify.

Returns:

The resulting string.

parseDebugString

@Nonnull
public static <Message extends PMessage<Message>> Message parseDebugString(java.lang.String string,
                                                                           PMessageDescriptor<Message> descriptor)

Parses a pretty formatted string, and makes exceptions unchecked.

Type Parameters:

Message - The message type.

Parameters:

string - The message string to parse.

descriptor - The message descriptor.

Returns:

The parsed message.

compact

public PrettySerializer compact()

Make a PrettySerializer that generates content similar to the PMessage asString methods. The output of this has very little whitespace, so can be pretty difficult to read. It's similar to the string() variant, but without the qualified name prefix.

Returns:

Compact pretty serializer.

string

public PrettySerializer string()

Make a PrettySerializer that generates content similar to the PMessage toString methods. The output of this has very little whitespace, so can be pretty difficult to read. It prefixes the message with the root message qualified name, as any PMessage.toString() would expect.

Returns:

String pretty serializer.

config

public PrettySerializer config()

Make a PrettySerializer that generates content similar to what the ProvidenceConfig reads. It will not make use of references or anything fancy though.

Returns:

Config-like pretty serializer.

serialize

public <Message extends PMessage<Message>> int serialize(@Nonnull
