Constructor Detail

CodespaceRange

public CodespaceRange(byte[] startBytes,
                      byte[] endBytes)

Creates a new instance of CodespaceRange. The length of both arrays has to be the same.
For one byte ranges startBytes and endBytes define a linear range of values. Double byte values define a rectangular range not a linear range. Examples:
<00> <20> defines a linear range from 0x00 up to 0x20.
<8140> to <9FFC> defines a rectangular range. The high byte has to be within 0x81 and 0x9F and the low byte has to be within 0x40 and 0xFC

Parameters:

startBytes -

endBytes -
