Utilities

public Utilities()

Method Details

getNextString

public static Optional<String> getNextString(ByteBuffer buffer)

Reads from a buffer to find the next string written

Strings in gamemaker buffers are ended with 0x00, if the functon can't find a 0x00 is will throw an IOException error

Parameters:

buffer - buffer to read from.

Returns:

the concatenated string

getLogger

public static Logger getLogger()

Singleton logger

Returns:

logger instance

addLogOutputFile

public static void addLogOutputFile(Level level,
 String dest)

getBuffer

public static String getBuffer(ByteBuffer buffer)

Returns the raw bytes of a buffer

Parameters:

buffer - the buffer to read from

Returns:

a string of all the bytes in the buffer, trimmed.

getHexBuffer

public static String getHexBuffer(ByteBuffer buffer)

newBuffer

public static ByteBuffer newBuffer()

Returns a LITTLE_ENDIAN ordered buffer with the default size

Returns:

new byte buffer

getPacket

public static Optional<Packet> getPacket(String header)

Reflectively loads a new packet instance from the given header.

Parameters:

header - the class name to load from.

Returns:

optional of packet, empty if error occurs.

getGSONPacket

public static Optional<GSONPacket> getGSONPacket(String header)

loadPacket

public static void loadPacket(ConnectionServer server,
 GMLInputBuffer buffer,
 String header,
 Client client)
