newList

@Deprecated
public IonList newList(Collection<? extends IonValue> values)
                throws ContainedValueException,
NullPointerException

Deprecated.

Description copied from interface: ValueFactory

Constructs a new list with given children.

Specified by:

newList in interface ValueFactory

Parameters:

values - the initial set of children. If null, then the new instance will have IonValue.isNullValue() == true.

Throws:

ContainedValueException - if any value in values has IonValue.getContainer() != null.

NullPointerException - if any value in values is null.

                throws ContainedValueException,
NullPointerException

Description copied from interface: ValueFactory

Constructs a new list with the given child.

This method is temporary until ValueFactory.newList(Collection) is removed. It's sole purpose is to avoid the doomed attempt to add all of the parameter's children to the new list; that will always throw ContainedValueException.

Specified by:

newList in interface ValueFactory

Parameters:

firstChild - the initial child of the new list.

Throws:

ContainedValueException - if child has IonValue.getContainer() != null.

NullPointerException - if child is null.

NullPointerException

Description copied from interface: ValueFactory

Constructs a new list with the given children.

Some edge cases are worth examples:

    factory.newList();                     // returns []
    factory.newList((IonValue[]) null);    // returns null.list

For clarity, applications should prefer ValueFactory.newEmptyList() and ValueFactory.newNullList() instead.

Specified by:

newList in interface ValueFactory

Parameters:

values - the initial sequence of children. If null, then the new instance will have IonValue.isNullValue() == true.
