java.util.Hashtable
   org.apache.tools.ant.util.LazyHashtable

LazyHashtable
public class LazyHashtable extends Hashtable (Code)
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


Field Summary
protected  booleaninitAllDone
    

Constructor Summary
public  LazyHashtable()
     No arg constructor.

Method Summary
public  booleancontains(Object value)
     Check if the table contains a particular value.
Parameters:
  value - the value to look for.
public  booleancontainsKey(Object value)
     Check if the table contains a particular key.
Parameters:
  value - the key to look for.
public  booleancontainsValue(Object value)
     Delegates to LazyHashtable.contains contains .
Parameters:
  value - the value to look for.
public  Enumerationelements()
     Get a enumeration over the elements.
protected  voidinitAll()
     Used to be part of init.
public  booleanisEmpty()
     Check if the table is empty.
public  Enumerationkeys()
     Get an enumeration over the keys.
public  intsize()
     Get the size of the table.

Field Detail
initAllDone
protected boolean initAllDone(Code)




Constructor Detail
LazyHashtable
public LazyHashtable()(Code)
No arg constructor.




Method Detail
contains
public boolean contains(Object value)(Code)
Check if the table contains a particular value.
Parameters:
  value - the value to look for. true if the table contains the value.



containsKey
public boolean containsKey(Object value)(Code)
Check if the table contains a particular key.
Parameters:
  value - the key to look for. true if the table contains key.



containsValue
public boolean containsValue(Object value)(Code)
Delegates to LazyHashtable.contains contains .
Parameters:
  value - the value to look for. true if the table contains the value.



elements
public Enumeration elements()(Code)
Get a enumeration over the elements. an enumeration.



initAll
protected void initAll()(Code)
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.



isEmpty
public boolean isEmpty()(Code)
Check if the table is empty. true if it is.



keys
public Enumeration keys()(Code)
Get an enumeration over the keys. an enumeration.



size
public int size()(Code)
Get the size of the table. the size.
