Class WorkerIdentity.ParserV1

java.lang.Object

alluxio.wire.WorkerIdentity.ParserV1

Enclosing class:

WorkerIdentity

public static class WorkerIdentity.ParserV1
extends Object

Parser for WorkerIdentity that is based on a UUID.
Code that needs to be forward- and backward-compatible should not rely on a version specific parser implementation.

Method Detail

getVersion

public int getVersion()

parseIdentifier

protected byte[] parseIdentifier(com.google.protobuf.ByteString identifier)
                          throws ProtoParsingException

Throws:

ProtoParsingException

getVersionSpecificRepresentation0

protected UUID getVersionSpecificRepresentation0(WorkerIdentity identity)

fromUUID

public WorkerIdentity fromUUID(UUID uuid)

Parses from a UUID representation.
Note that the identity being a UUID is an implementation detail that is specific to version 1 of the definition of a worker identity. Code that needs to be backwards-compatible should not rely on a version specific parser implementation.

Parameters:

uuid - the uuid representing the worker identity

Returns:

the worker identity

fromUUID

public WorkerIdentity fromUUID(String uuid)
                        throws IllegalArgumentException

Parses a worker identity from a string representation of a UUID.
Note that the identity being a UUID is an implementation detail that is specific to version 1 of the definition of a worker identity. Code that needs to be backwards-compatible should not rely on a version specific parser implementation.

Parameters:

uuid - the string representation of the UUID that is used as the worker's identity

Returns:

worker identity

Throws:

IllegalArgumentException - if the string is not a valid representation of a UUID

See Also:

fromUUID(UUID)

toUUID

public UUID toUUID(WorkerIdentity identity)
            throws IllegalArgumentException

Converts to a UUID.

Parameters:

identity - the worker identity

Returns:

identity represented as a UUID

Throws:

IllegalArgumentException - if the identity was not created from a UUID

getVersionSpecificRepresentation

public Object getVersionSpecificRepresentation(WorkerIdentity identity)

Returns:

a version-specific representation of worker identity

ensureVersionMatch

protected void ensureVersionMatch(WorkerIdentity identity)
                           throws IllegalArgumentException

Throws:

IllegalArgumentException

toProto

public WorkerIdentity toProto(WorkerIdentity workerIdentity)

Converts to a protobuf representation.

Parameters:

workerIdentity - the object to convert

Returns:

worker identity

fromProto

public WorkerIdentity fromProto(WorkerIdentity workerIdentityProto)
                         throws ProtoParsingException

Parses from a Protobuf representation.

Parameters:

workerIdentityProto - the proto message

Returns:

the worker identity

Throws:

MissingRequiredFieldsParsingException - if the version or the identifier fields are missing in the protobuf representation

InvalidVersionParsingException - if the version is not getVersion()

ProtoParsingException - if the protobuf representation is invalid
