Method Detail

getValuesOrThrowIfExpression

public static <T> SortedSet<T> getValuesOrThrowIfExpression(Collection<ValueOrExpression<T>> wrappedValues,
                                                            Comparator<T> comparator)
                                                     throws ExpressionException

Returns a sorted set containing values from the provided collection of wrapped values.

This method must be used when type T is not comparable. If T is comparable, then equivalent method without a comparator argument can be used.

Type Parameters:

T - The type of the values, which need not be comparable.

Parameters:

wrappedValues - The wrapped values to be sorted.

comparator - The comparator for values of type T.

Returns:

a sorted set containing the provided values

Throws:

ExpressionException - If the set contains an expression.

getValuesOrThrowIfExpression

public static <T extends Comparable<T>> SortedSet<T> getValuesOrThrowIfExpression(Collection<ValueOrExpression<T>> wrappedValues)
                                                                           throws ExpressionException

Returns a sorted set containing values from the provided collection of wrapped values.

This method can only be used when type T is comparable. If T is not comparable, then the equivalent method with the comparator argument must be used.

Type Parameters:

T - The type of the values, which need not be comparable.

Parameters:

wrappedValues - The wrapped values to be sorted.

Returns:

a sorted set containing the provided values

Throws:

ExpressionException - if the set contains an expression

asSetOfValueOrExpression

public static <T> Collection<ValueOrExpression<T>> asSetOfValueOrExpression(Collection<T> values)

Returns a collection of wrapped values from the provided collection of values.

Type Parameters:

T - the type of the values

Parameters:

values - values to wrap

Returns:

a collection of wrapped values

asSetOfValueOrExpression

@SafeVarargs
public static <T> Collection<ValueOrExpression<T>> asSetOfValueOrExpression(T... values)

Returns a collection of wrapped values from the provided values.

Type Parameters:

T - the type of the values

Parameters:

values - values to wrap

Returns:

a collection of wrapped values
