PairwiseString

SubString

All Implemented Interfaces:

Serializable, Cloneable

Enclosing class:

PairwiseString

public static class PairwiseString.SubString
extends PairwiseString

Represents the substring invariant between corresponding elements of two sequences of String. Prints as x[] is a substring of y[].

Field Detail

dkconfig_enabled

public static boolean dkconfig_enabled

Boolean. True iff SubString invariants should be considered.

Constructor Detail

SubString

protected SubString(PptSlice ppt,
                    boolean swap)

SubString

protected SubString(boolean swap)

Method Detail

get_proto

public static PairwiseString.SubString 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

protected PairwiseString.SubString instantiate_dyn( PairwiseString.SubString 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 PairwiseString.SubString this,
                             OutputFormat format)

Description copied from class: PairwiseString

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 PairwiseString

eq_check

public boolean eq_check(String x,
                        String y)

Description copied from class: PairwiseString

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

Specified by:

eq_check in class PairwiseString

computeConfidence

protected double computeConfidence()

Justified as long as there are samples.

Overrides:

computeConfidence in class TwoSequenceString

Returns:

confidence of this invariant

See Also:

Invariant.getConfidence()

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
