Constructor Details

ConstraintIterator

public ConstraintIterator(Container container)

Constructs a ConstraintIterator for the given FormLayout container. Useful to iterate over the container's CellConstraints.

Parameters:

container - the layout container

Throws:

IllegalArgumentException - if the container's layout is not a FormLayout

Method Details

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:

NoSuchElementException - iteration has no more elements.
