Methods

append() : void
length() : DataSize
writeBits() : void
writeBytes() : void
writeVarInts() : void: Write values using variable-length encoding (VarInt/ULEB128).

append()


    public
                    append(string $buffer) : void

Parameters

$buffer : string

length()


    public
                    length() : DataSize

Return values

DataSize

writeBits()


    public
                    writeBits(array<string|int, int> $bits) : void

Parameters

$bits : array<string|int, int>

writeBytes()


    public
                    writeBytes(array<string|int, int> $bytes) : void

Parameters

$bytes : array<string|int, int>

writeVarInts()

Write values using variable-length encoding (VarInt/ULEB128).


    public
                    writeVarInts(array<string|int, int> $values) : void

VarInt encoding uses the most significant bit of each byte as a continuation bit. Values are encoded in little-endian byte order with 7 bits of data per byte. Negative values are treated as unsigned 64-bit integers for proper encoding. This method handles all edge cases including overflow and ZigZag encoded values.

Parameters

$values : array<string|int, int>
