Deprecated.

Method Details

equals

@Deprecated
public static boolean equals(Vector<?> v1,
 Vector<?> v2)

Deprecated.

since 1.6.x.

Please use Vector.equals() or List.equals().

Parameters:

v1 - the first vector.

v2 - the second vector.

Returns:

true if the vectors are equal.

Since:

Ant 1.5

equals

@Deprecated
public static boolean equals(Dictionary<?,?> d1,
 Dictionary<?,?> d2)

Deprecated.

since 1.6.x.

Dictionary does not have an equals. Please use Map.equals().

Follows the equals contract of Java 2's Map.

Parameters:

d1 - the first directory.

d2 - the second directory.

Returns:

true if the directories are equal.

Since:

Ant 1.5

flattenToString

@Deprecated
public static String flattenToString(Collection<?> c)

Deprecated.

use stream().collect(Collectors.joining(","))

Creates a comma separated list of all values held in the given collection.

Parameters:

c - collection to transform

Returns:

string representation of the collection

Since:

Ant 1.8.0

putAll

@Deprecated
public static <K,
V> void putAll(Dictionary<? super K,? super V> m1,
 Dictionary<? extends K,? extends V> m2)

Deprecated.

since 1.6.x.

Dictionary does not know the putAll method. Please use Map.putAll().

Type Parameters:

K - type of the key

V - type of the value

Parameters:

m1 - the to directory.

m2 - the from directory.

Since:

Ant 1.6

append

@Deprecated
public static <E> Enumeration<E> append(Enumeration<E> e1,
 Enumeration<E> e2)

Deprecated.

use Stream.concat(Collections.list(e1).stream(), Collections.list(e2).stream()) .collect(Collectors.collectingAndThen(Collectors.toList(), Collections::enumeration))

Append one enumeration to another. Elements are evaluated lazily.

Type Parameters:

E - element type

Parameters:

e1 - the first enumeration.

e2 - the subsequent enumeration.

Returns:

an enumeration representing e1 followed by e2.

Since:

Ant 1.6.3

asEnumeration

@Deprecated
public static <E> Enumeration<E> asEnumeration(Iterator<E> iter)

Deprecated.

use Collections.enumeration()

Type Parameters:

E - element type

Parameters:

iter - the Iterator to adapt.

Returns:

an Enumeration.

asIterator

@Deprecated
public static <E> Iterator<E> asIterator(Enumeration<E> e)

Deprecated.

use Collections.list(e).iterator()

Adapt the specified Enumeration to the Iterator interface.

Type Parameters:

E - element type

Parameters:

e - the Enumeration to adapt.

Returns:

an Iterator.

asCollection

@Deprecated
public static <T> Collection<T> asCollection(Iterator<? extends T> iter)

Deprecated.

instantiate a list and use forEachRemaining(list::add)

Returns a collection containing all elements of the iterator.

Type Parameters:

frequency

@Deprecated
public static int frequency(Collection<?> c,
 Object o)
