All Implemented Interfaces:

Serializable, Cloneable

Enclosing class:

StdString

public static class StdString.SubString
extends StdString

Represents the substring invariant between two String scalars. 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 StdString.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 StdString.SubString instantiate_dyn( StdString.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 StdString.SubString this,
                             OutputFormat format)

Description copied from class: StdString

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 StdString

eq_check

public boolean eq_check(String x,
                        String y)

Description copied from class: StdString

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

Specified by:

eq_check in class StdString

computeConfidence

protected double computeConfidence()

Justified as long as there are samples.

Overrides:

computeConfidence in class TwoString

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
