Class LazyHashtable<K,V>

java.lang.Object

java.util.Dictionary<K,V>

java.util.Hashtable<K,V>

org.apache.tools.ant.util.LazyHashtable<K,V>

All Implemented Interfaces:

Serializable, Cloneable, Map<K,V>

@Deprecated
public class LazyHashtable<K,V>
extends Hashtable<K,V>

Deprecated.

Hashtable implementation that allows delayed construction of expensive objects All operations that need access to the full list of objects will call initAll() first. Get and put are cheap.

Since:

Ant 1.6

Constructor Details

LazyHashtable

public LazyHashtable()

Deprecated.

No arg constructor.

Method Details

initAll

protected void initAll()

Deprecated.

Used to be part of init. It must be done once - but we delay it until we do need _all_ tasks. Otherwise we just get the tasks that we need, and avoid costly init.

elements

public Enumeration<V> elements()

Deprecated.

Get a enumeration over the elements.

Overrides:

elements in class Hashtable<K,V>

Returns:

an enumeration.

isEmpty

public boolean isEmpty()

Deprecated.

Check if the table is empty.

Specified by:

isEmpty in interface Map<K,V>

Overrides:

isEmpty in class Hashtable<K,V>

Returns:

true if it is.

size

public int size()

Deprecated.

Get the size of the table.

Specified by:

size in interface Map<K,V>

Overrides:

size in class Hashtable<K,V>

Returns:

the size.

contains

public boolean contains(Object value)

Deprecated.

Check if the table contains a particular value.

Overrides:

contains in class Hashtable<K,V>

Parameters:

value - the value to look for.

Returns:

true if the table contains the value.

containsKey

public boolean containsKey(Object value)

Deprecated.

Check if the table contains a particular key.

Specified by:

containsKey in interface Map<K,V>

Overrides:

containsKey in class Hashtable<K,V>

Parameters:

value - the key to look for.

Returns:

true if the table contains key.

containsValue

public boolean containsValue(Object value)

Deprecated.

Delegates to contains.

Specified by:

containsValue in interface Map<K,V>

Overrides:

containsValue in class Hashtable<K,V>

Parameters:

value - the value to look for.

Returns:

true if the table contains the value.

keys

public Enumeration<K> keys()

Deprecated.

Get an enumeration over the keys.

Overrides:

keys in class Hashtable<K,V>

Returns:

an enumeration.
