Method Detail

getValue

public java.lang.Object getValue()

isOne

public boolean isOne(Type type)

Return true, if this value is a one of the given type. This is used for ++ and -- instructions.

Parameters:

type - the type for which this must be a one. This may be different from the type this value actually is.
