Method Detail

argument

public final A argument()

Description copied from interface: ModelStatement

Returns statement argument.

Returns:

statement argument or null if statement does not have argument.

rawArgument

public final String rawArgument()

Description copied from interface: DeclaredStatement

Returns statement argument as was present in original source.

Returns:

statement argument as was present in original source or null, if statement does not take argument.

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
