                         throws IOException

Encodes a value using the variable-length encoding from Google Protocol Buffers. It uses zig-zag encoding to efficiently encode signed values. If values are known to be non-negative, writeVarLongUnsigned(long, DataOutput) should be used.

Parameters:

value - Value to encode

out - Data output.

Throws:

IOException - if failed to write value.

writeVarLongUnsigned

public static void writeVarLongUnsigned(long value,
                                        DataOutput out)
                                 throws IOException

Encodes a value using the variable-length encoding from Google Protocol Buffers. Zig-zag is not used, so input must not be negative. If values can be negative, use writeVarLong(long, DataOutput) instead. This method treats negative input as like a large unsigned value.

Parameters:

value - Value to encode (must be non-negative).

out - Data output.

Throws:

IOException - if failed to write value.

writeVarInt

public static void writeVarInt(int value,
                               DataOutput out)
                        throws IOException

Encodes a value using the variable-length encoding from Google Protocol Buffers. It uses zig-zag encoding to efficiently encode signed values. If values are known to be non-negative, writeVarIntUnsigned(int, DataOutput) should be used.

Parameters:

value - Value to encode

out - Data output.

Throws:

IOException - if failed to write value.

writeVarIntUnsigned

public static void writeVarIntUnsigned(int value,
                                       DataOutput out)
                                throws IOException

Encodes a value using the variable-length encoding from Google Protocol Buffers. Zig-zag is not used, so input must not be negative. If values can be negative, use writeVarInt(int, DataOutput) instead. This method treats negative input as like a large unsigned value.

Parameters:

value - Value to encode (must be non-negative).

out - Data output.

Throws:

IOException - if failed to write value.

readVarLong

public static long readVarLong(DataInput in)
                        throws IOException

Reads a value that was encoded via writeVarLong(long, DataOutput).

Parameters:

in - Data input.

Returns:

Value.

Throws:
