Field Detail

dkconfig_enabled

public static boolean dkconfig_enabled

Boolean. True iff SubSequence invariants should be considered.

Constructor Detail

SubSequenceFloat

protected SubSequenceFloat(PptSlice ppt)

Method Detail

get_proto

public static SubSequenceFloat get_proto()

Returns the prototype invariant for SubSequenceFloat

enabled

public boolean enabled()

returns whether or not this invariant is enabled

Overrides:

enabled in class Invariant

instantiate_dyn

protected SubSequenceFloat instantiate_dyn(PptSlice slice)

instantiates the invariant on the specified slice

Overrides:

instantiate_dyn in class Invariant

Returns:

the new invariant

resurrect_done_swapped

protected Invariant resurrect_done_swapped()

Description copied from class: TwoSequenceFloat

Swaps the variables by inverting the state of swap.

Overrides:

resurrect_done_swapped in class TwoSequenceFloat

format_using

public String format_using(OutputFormat format)

Specified by:

format_using in class Invariant

format_daikon

public String format_daikon()

format_simplify

public String format_simplify()

check_modified

public InvariantStatus check_modified(double[] a1,
                                      double[] a2,
                                      int count)

Specified by:

check_modified in class TwoSequenceFloat

add_modified

public InvariantStatus add_modified(double[] a1,
                                    double[] a2,
                                    int count)

Description copied from class: TwoSequenceFloat

Default implementation simply calls check. Subclasses can override.

Overrides:

add_modified in class TwoSequenceFloat

computeConfidence

protected double computeConfidence()

Description copied from class: Invariant

This method computes the confidence that this invariant occurred by chance. Users should use getConfidence() instead.

Overrides:

computeConfidence in class TwoSequenceFloat

See Also:

Invariant.getConfidence()

isObviousSubSequence

public static DiscardInfo isObviousSubSequence(Invariant inv,
                                               VarInfo subvar,
                                               VarInfo supervar)

Returns:

a DiscardInfo, or null if the Invariant is not an obvious subsequence

isObviousSubSequence

public static Pair<DiscardCode,String> isObviousSubSequence(VarInfo subvar,
                                                            VarInfo supervar)

Returns:

a Pair of a DiscardCode and a discardReason string, or null if the Invariant is not an obvious subsequence

find

public static SubSequenceFloat find(PptSlice ppt)

isObviousStatically

public DiscardInfo isObviousStatically(VarInfo[] vis)

Description copied from class: Invariant

Return true if this invariant is necessarily true from a fact that can be determined statically -- for the given varInfos rather than the varInfos of this. Conceptually, this means "is this invariant statically obvious if its VarInfos were switched with vis?" Intended to be overridden by subclasses. Should only do static checking. Precondition: vis.length == this.ppt.var_infos.length

Overrides:

isObviousStatically in class Invariant

Parameters:

vis - The VarInfos this invariant is obvious over. The position and data type of the variables is the *same* as that of this.ppt.var_infos.

isObviousDynamically

public DiscardInfo isObviousDynamically(VarInfo[] vis)

Description copied from class: Invariant

Return non-null if this invariant is necessarily true from a fact that can be determined dynamically (after checking data) -- for the given varInfos rather than the varInfos of this. Conceptually, this means, "Is this invariant dynamically obvious if its VarInfos were switched with vis?" Intended to be overriden by subclasses so they can filter invariants after checking; the overriding method should first call "super.isObviousDynamically(vis)". Since this method is dynamic, it should only be called after all processing.

Overrides:

isObviousDynamically in class Invariant

isObviousSubSequenceDynamically

public static boolean isObviousSubSequenceDynamically(Invariant inv,
                                                      VarInfo subvar,
                                                      VarInfo supervar)

Returns true if the two original variables are related in a way that makes subsequence or subset detection not informative.

isSameFormula

public boolean isSameFormula(Invariant inv)

Description copied from class: TwoSequenceFloat

Return true if both invariants are the same class and the order of the variables (swap) is the same.

Overrides:

isSameFormula in class TwoSequenceFloat

Returns:

true iff the two invariants represent the same mathematical formula. Does not consider the context such as variable names, confidences, sample counts, value counts, or related quantities. As a rule of thumb, if two invariants format the same, this method returns true. Furthermore, in many cases, if an invariant does not involve computed constants (as "x>c" and "y=ax+b" do for constants a, b, and c), then this method vacuously returns true.

get_ni_suppressions

public NISuppressionSet get_ni_suppressions()

returns the ni-suppressions for SubSequence

Overrides:

get_ni_suppressions in class Invariant
