getAllChildrenAsContainer

@Nonnull
@ReturnsMutableCopy
public static IMicroContainer getAllChildrenAsContainer(@Nonnull

Create a micro container with all children of the passed node. If the passed node has no children, an empty object is returned. The resulting container contains a clone of each child node so that the original objects is not modified.

Parameters:

aParent - The parent node to get the children from. May not be null.

Returns:

The micro container and never null but maybe empty.

getAllOriginalChildrenAsContainer

@Nonnull
@ReturnsMutableCopy
public static IMicroContainer getAllOriginalChildrenAsContainer(@Nonnull
                                                                           IMicroNode aParent)

Create a micro container with all children of the passed node. If the passed node has no children, an empty object is returned. The resulting container contains the original child nodes so that they no longer belong to the original object. THis implies that the original object is modified!

Parameters:

aParent - The parent node to get the children from. May not be null.

Returns:

The micro container and never null but maybe empty.
