Constructor Detail

ProtobufRecord

public ProtobufRecord(java.io.ByteArrayOutputStream byteArrayOutputStream,
                      ProtobufParser parser)
               throws java.io.IOException

Create a new Protobuf record

Parameters:

byteArrayOutputStream - A reusable ByteArrayOutputStream to avoid unnecessary allocations

parser - The parser to use to create the record

Throws:

java.io.IOException - - if an IO error occurs

Method Detail

asDouble

public double asDouble()

Get as a double (WireType.SIXTY_FOUR_BIT)

Returns:

the double

asFixed32

public byte[] asFixed32()

Get as 32 bits (WireType.THIRTY_TWO_BIT)

Returns:

a byte array of the 32 bits (4 bytes)

asFixed64

public byte[] asFixed64()

Get as 64 bits (WireType.SIXTY_FOUR_BIT)

Returns:

a byte array of the 64 bits (8 bytes)

asFloat

public float asFloat()

Get as a float (WireType.THIRTY_TWO_BIT)

Returns:

the float

asSignedVarInt

public java.lang.Number asSignedVarInt()

Get the signed var int (WireType#VARINT). These are specially encoded so that they take up less space.

Returns:

The signed var int (sint32 or sint64)

asString

public java.lang.String asString()

Get as a string (WireType.LENGTH_DELIMITED)

Returns:

The string (encoded as StandardCharsets.UTF_8)

asUnsignedVarInt

Get the var int (WireType#VARINT)

Returns:

The var int (int32, int64, uint32, uint64, bool, enum)

close

public void close()

Specified by:

close in interface java.lang.AutoCloseable

getBytes

public byte[] getBytes()

Get the raw bytes for this record

Returns:

The bytes

getField

public int getField()

Get the field value

Returns:

The field value

getType

public WireType getType()

Get the WireType of the data

Returns:

The WireType of the data
