Class FormLayoutUtils.ConstraintIterator

  • Enclosing class:
    FormLayoutUtils
    public static final class FormLayoutUtils.ConstraintIterator
extends java.lang.Object
    Iterates over a FormLayout container's CellConstraints. The container's child component collection and the layout's constraints collection must not be changed during the iteration; otherwise the behavior of this iterator is unspecified and unsafe.
    See Also:
    FormLayout, CellConstraints

    • Method Detail

      • hasNext

        public boolean hasNext()
        Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)
        Returns:
        true if the iterator has more elements.

      • nextConstraints

        public CellConstraints nextConstraints()
        Returns the next element in the iteration.
        Returns:
        the next element in the iteration.
        Throws:
        java.util.NoSuchElementException - iteration has no more elements.
