Method Detail

writeStdCompare

protected boolean writeStdCompare(int type,
                                  boolean simulate)

writes a std compare. This involves the tokens IF_ICMPEQ, IF_ICMPNE, IF_ICMPEQ, IF_ICMPNE, IF_ICMPGE, IF_ICMPGT, IF_ICMPLE and IF_ICMPLT

Overrides:

writeStdCompare in class BinaryExpressionWriter

Parameters:

type - the token type

Returns:

true if a successful std compare write

writeSpaceship

protected boolean writeSpaceship(int type,
                                 boolean simulate)

writes the spaceship operator, type should be COMPARE_TO

Overrides:

writeSpaceship in class BinaryExpressionWriter

Parameters:

type - the token type

Returns:

true if a successful spaceship operator write
