Method Detail

getBytes

public static byte[] getBytes(int value)

Converts a signed int to a byte array.

The byte order is big-endian.

Parameters:

value - the int value.

Returns:

an array with four bytes.

getBytes

public static byte[] getBytes(long value)

Converts a signed long to a byte array.

The byte order is big-endian.

Parameters:

value - the long value.

Returns:

an array with eight bytes.

getBytes

public static byte[] getBytes(short value)

Converts a signed short to a byte array.

The byte order is big-endian.

Parameters:

value - the short value.

Returns:

an array with two bytes.

getFiveBytes

public static byte[] getFiveBytes(long value)

Converts the lowest five bytes of an unsigned long to a byte array.

The byte order is big-endian.

Parameters:

value - the long value, must not be negative.

Returns:

an array with five bytes.

getVariableByteSigned

public static byte[] getVariableByteSigned(int value)

Converts a signed int to a variable length byte array.

The first bit is for continuation info, the other six (last byte) or seven (all other bytes) bits for data. The second bit in the last byte indicates the sign of the number.

Parameters:

value - the int value.

Returns:

an array with 1-5 bytes.

getVariableByteUnsigned

public static byte[] getVariableByteUnsigned(int value)

Converts an unsigned int to a variable length byte array.

The first bit is for continuation info, the other seven bits for data.

Parameters:

value - the int value, must not be negative.

Returns:

an array with 1-5 bytes.
