Field Detail

dkconfig_enabled

public static boolean dkconfig_enabled

Boolean. True iff bitwise complement invariants should be considered.

protected BitwiseComplement()

Method Detail

get_proto

public static PairwiseNumericInt.BitwiseComplement get_proto()

Returns the prototype invariant.

enabled

public boolean enabled()

Description copied from class: Invariant

Returns whether or not this class of invariants is currently enabled.

Its implementation is almost always return dkconfig_enabled;.

Specified by:

enabled in class Invariant

instantiate_dyn

protected PairwiseNumericInt.BitwiseComplement instantiate_dyn( PairwiseNumericInt.BitwiseComplement this,
                                                               PptSlice slice)

Description copied from class: Invariant

Instantiates (creates) an invariant of the same class on the specified slice. Must be overridden in each class. Must be used rather than Invariant.clone() so that checks in Invariant.instantiate(daikon.PptSlice) for reasonable invariants are done.

The implementation of this method is almost always return new <em>InvName</em>(slice);

Specified by:

instantiate_dyn in class Invariant

Returns:

the new invariant

is_symmetric

@Pure
public boolean is_symmetric()

Description copied from class: BinaryInvariant

Returns true if the binary function is symmetric (x,y ⇒ y,x). Subclasses that are symmetric should override.

Overrides:

is_symmetric in class BinaryInvariant

get_format_str

public String get_format_str(@GuardSatisfied PairwiseNumericInt.BitwiseComplement this,
                             OutputFormat format)

Description copied from class: PairwiseNumericInt

Return a format string for the specified output format. Each instance of %varN% will be replaced by the correct name for varN.

Specified by:

get_format_str in class PairwiseNumericInt

eq_check

public boolean eq_check(long x,
                        long y)

Check to see if x == ~y .

Specified by:

eq_check in class PairwiseNumericInt
