RangeInt

EqualZero

All Implemented Interfaces:

Serializable, Cloneable

Enclosing class:

RangeInt

public static class RangeInt.EqualZero
extends RangeInt

Internal invariant representing long scalars that are equal to zero. Used for non-instantiating suppressions. Will never print since OneOf accomplishes the same thing.

Method Detail

get_proto

public static RangeInt.EqualZero 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

public RangeInt.EqualZero instantiate_dyn( RangeInt.EqualZero 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 RangeInt.EqualZero this,
                             OutputFormat format)

Description copied from class: RangeInt

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 RangeInt

eq_check

public boolean eq_check(long x)

Description copied from class: RangeInt

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

Specified by:

eq_check in class RangeInt
