Method Details

unmaskList

protected static final @NonNull ImmutableList<? extends @NonNull EffectiveStatement<?,?>> unmaskList(@NonNull Object masked)

Utility method for recovering singleton lists squashed by maskList(ImmutableList).

Parameters:

masked - list to unmask

Returns:

Unmasked list

Throws:

NullPointerException - if masked is null

ClassCastException - if masked object does not match EffectiveStatement

hashCode

public final int hashCode()

Overrides:

hashCode in class Object

equals

public final boolean equals(Object obj)

Overrides:

equals in class Object

toString

public final String toString()

Overrides:

toString in class Object

addToStringAttributes

protected MoreObjects.ToStringHelper addToStringAttributes(MoreObjects.ToStringHelper helper)

maskList

protected static final @NonNull Object maskList(ImmutableList<?> list)

Utility method for squashing singleton lists into single objects. This is a CPU/mem trade-off, which we are usually willing to make: for the cost of an instanceof check we can save one object and re-create it when needed. The inverse operation is #unmaskSubstatements(Object)}.

Parameters:

list - list to mask

Returns:

Masked list

Throws:

NullPointerException - if list is null

unmaskList

protected static final <T>
@NonNull ImmutableList<T> unmaskList(@NonNull Object masked,
 @NonNull Class<T> type)

Utility method for recovering singleton lists squashed by maskList(ImmutableList).

Parameters:

masked - list to unmask

Returns:

Unmasked list

Throws:

NullPointerException - if any argument is null

ClassCastException - if masked object does not match expected class

maskSet

protected static final @NonNull Object maskSet(ImmutableSet<?> set)

unmaskSet

protected static final <T> @NonNull ImmutableSet<T> unmaskSet(@NonNull Object masked,
 @NonNull Class<T> type)
