PairwiseNumericInt

BitwiseSubset

All Implemented Interfaces:

Serializable, Cloneable

Enclosing class:

PairwiseNumericInt

public static class PairwiseNumericInt.BitwiseSubset
extends PairwiseNumericInt

Represents the bitwise subset invariant between corresponding elements of two sequences of long; that is, the bits of y[] are a subset of the bits of x[]. Prints as x[] = y[] | x[].

Field Detail

dkconfig_enabled

public static boolean dkconfig_enabled

Boolean. True iff bitwise subset invariants should be considered.

Constructor Detail

BitwiseSubset

protected BitwiseSubset(PptSlice ppt,
                        boolean swap)

BitwiseSubset

protected BitwiseSubset(boolean swap)

Method Detail

get_proto

public static PairwiseNumericInt.BitwiseSubset get_proto(boolean swap)

Returns the prototype invariant.

enabled

public boolean enabled()

Returns whether or not this invariant is enabled.

Specified by:

enabled in class Invariant

instantiate_dyn

public PairwiseNumericInt.BitwiseSubset instantiate_dyn( PairwiseNumericInt.BitwiseSubset 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

get_format_str

public String get_format_str(@GuardSatisfied PairwiseNumericInt.BitwiseSubset 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)

Description copied from class: PairwiseNumericInt

Returns true if x and y don't invalidate the invariant.

Specified by:

eq_check in class PairwiseNumericInt

obvious_checks

public InvDef[][] obvious_checks(VarInfo[] vis)

This needs to be an obvious check and not a suppression for sequences because there is no consistent way to check that var1 and var2 have the same length (for derivations).

Overrides:

obvious_checks in class PairwiseNumericInt

get_ni_suppressions

@Pure
public NISuppressionSet get_ni_suppressions()

Returns a list of non-instantiating suppressions for this invariant.

Overrides:

get_ni_suppressions in class Invariant

Returns:

the set of non-instantiating suppressions for this invariant
