BufferUtil

public BufferUtil()

Method Detail

toInt

public static int toInt(Buffer buffer)

Convert buffer to an integer. Parses up to the first non-numeric character. If no number is found an IllegalArgumentException is thrown

Parameters:

buffer - A buffer containing an integer. The position is not changed.

Returns:

an int

toLong

public static long toLong(Buffer buffer)

Convert buffer to an long. Parses up to the first non-numeric character. If no number is found an IllegalArgumentException is thrown

Parameters:

buffer - A buffer containing an integer. The position is not changed.

Returns:

an int

putHexInt

public static void putHexInt(Buffer buffer,
                             int n)

prependHexInt

public static void prependHexInt(Buffer buffer,
                                 int n)

Add hex integer BEFORE current getIndex.

Parameters:

buffer -

size -

putDecInt

public static void putDecInt(Buffer buffer,
                             int n)

putDecLong

public static void putDecLong(Buffer buffer,
                              long n)

toBuffer

public static Buffer toBuffer(long value)

putCRLF
