Interface SequenceValue

All Superinterfaces:

Iterable<AnyValue>

All Known Implementing Classes:

ArrayValue, BooleanArray, ByteArray, CharArray, FloatArray, IntArray, ListValue, LongArray, ShortArray, StringArray, TextArray

public interface SequenceValue
extends Iterable<AnyValue>

Values that represent sequences of values (such as Lists or Arrays) need to implement this interface. Thus we can get an equality check that is based on the values (e.g. List.equals(ArrayValue) ) Values that implement this interface also need to overwrite isSequence() to return true! Note that even though SequenceValue extends Iterable iterating over the sequence using iterator() might not be the most performant method. Branch using iterationPreference() in performance critical code paths.
