Method Detail

int32Size

public static int int32Size(int value)

Computes the number of bytes that would be needed to encode a signed variable-length integer of up to 32 bits.

int64Size

public static int int64Size(long value)

Computes the number of bytes that would be needed to encode a signed variable-length integer of up to 64 bits.

tagSize

public static int tagSize(int fieldNumber,
          WireType wireType)

Computes the number of bytes that would be needed to encode a tag.

messageSize

public static int messageSize(int fieldNumber,
              int messageLength)

Computes the number of bytes that would be needed to encode a message field with a given tag number and length.

writeTag

public static int writeTag(int fieldNumber,
           WireType wireType,
           byte[] buffer,
           int offset)

Writes a tag value (as a variable-length integer combining a field number and wire type) to the given output array.

writeVarint

public static int writeVarint(long value,
              byte[] buffer,
              int offset)

Writes a variable-length integer into the given output array. The input value is treated as unsigned.

messageHeaderSize

public static int messageHeaderSize(int fieldNumber,
                    int byteCount)

Returns the length in bytes of a message header consisting of a field number, wire type, and message length in bytes.

writeMessageHeader

public static int writeMessageHeader(int fieldNumber,
                     byte[] buffer,
                     int bufferOffset,
                     int byteCount)

Writes a message header into the given output array, consisting of the field number, wire type, and message length in bytes.

Parameters:

bufferOffset - the offset at which to start writing to the output buffer

Returns:

the number of bytes written to form the header

makeTag

public static int makeTag(int fieldNumber,
          WireType wireType)

Makes a tag value given a field number and wire type.
