public Class NonSynchronizedProperties

Overrides java.util.Properties.clear.

Implements java.util.Map.clear.

Doc from java.util.Hashtable.clear.

Clears this hashtable so that it contains no keys.

Annotations

@Override

Overrides java.util.Properties.clone.

Doc from java.util.Hashtable.clone.

Creates a shallow copy of this hashtable. All the structure of the hashtable itself is copied, but the keys and values are not cloned. This is a relatively expensive operation.

Returns:Object

a clone of the hashtable

Annotations

@Override

Overrides java.util.Properties.contains.

Doc from java.util.Hashtable.contains.

Tests if some key maps into the specified value in this hashtable. This operation is more expensive than the containsKey method.

Note that this method is identical in functionality to containsValue, (which is part of the Map interface in the collections framework).

Parameters

value:Object

a value to search for

Returns:boolean

true if and only if some key maps to the value argument in this hashtable as determined by the equals method; false otherwise.

Annotations

@Override

Overrides java.util.Properties.containsKey.

Implements java.util.Map.containsKey.

Doc from java.util.Hashtable.containsKey.

Tests if the specified object is a key in this hashtable.

Parameters

key:Object

possible key

Returns:boolean

true if and only if the specified object is a key in this hashtable, as determined by the equals method; false otherwise.

Annotations

@Override

Overrides java.util.Properties.containsValue.

Implements java.util.Map.containsValue.

Doc from java.util.Hashtable.containsValue.

Returns true if this hashtable maps one or more keys to this value.

Note that this method is identical in functionality to contains (which predates the Map interface).

Parameters

value:Object

value whose presence in this hashtable is to be tested

Returns:boolean

true if this map maps one or more keys to the specified value

Annotations

@Override

Overrides java.util.Properties.elements.

Doc from java.util.Hashtable.elements.

Returns an enumeration of the values in this hashtable. Use the Enumeration methods on the returned object to fetch the elements sequentially. If the hashtable is structurally modified while enumerating over the values then the results of enumerating are undefined.

Returns:Enumeration<Object>

an enumeration of the values in this hashtable.

Annotations

@Override

Overrides java.util.Properties.entrySet.

Implements java.util.Map.entrySet.

Doc from java.util.Hashtable.entrySet.

Returns a Set view of the mappings contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation, or through the setValue operation on a map entry returned by the iterator) the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.

Returns:Set<Map.Entry<Object, Object>>

Doc from java.util.Map.entrySet.

a set view of the mappings contained in this map

Annotations

@Override

Overrides java.util.Properties.equals.

Implements java.util.Map.equals.

Doc from java.util.Hashtable.equals.

Compares the specified Object with this Map for equality, as per the definition in the Map interface.

Parameters

o:Object

object to be compared for equality with this hashtable

Returns:boolean

true if the specified Object is equal to this Map

Annotations

@Override

Overrides java.util.Properties.get.

Implements java.util.Map.get.

Doc from java.util.Hashtable.get.

Returns the value to which the specified key is mapped, or null if this map contains no mapping for the key.

More formally, if this map contains a mapping from a key k to a value v such that (key.equals(k)), then this method returns v; otherwise it returns null. (There can be at most one such mapping.)

Parameters

key:Object

the key whose associated value is to be returned

Returns:Object

the value to which the specified key is mapped, or null if this map contains no mapping for the key

Annotations

@Override

Overrides java.util.Properties.getProperty.

Doc from java.util.Properties.getProperty.

Searches for the property with the specified key in this property list. If the key is not found in this property list, the default property list, and its defaults, recursively, are then checked. The method returns the default value argument if the property is not found.

Parameters

key:String

the hashtable key.

defaultValue:String

a default value.

Returns:String

the value in this property list with the specified key value.

Annotations

@Override

Overrides java.util.Properties.getProperty.

Doc from java.util.Properties.getProperty.

Searches for the property with the specified key in this property list. If the key is not found in this property list, the default property list, and its defaults, recursively, are then checked. The method returns null if the property is not found.

Parameters

key:String

the property key.

Returns:String

the value in this property list with the specified key value.

Annotations

@Override

Overrides java.util.Properties.hashCode.

Implements java.util.Map.hashCode.

Doc from java.util.Hashtable.hashCode.

Returns the hash code value for this Map as per the definition in the Map interface.

Returns:int

Doc from java.util.Map.hashCode.

the hash code value for this map

Annotations

@Override

Overrides java.util.Properties.isEmpty.

Implements java.util.Map.isEmpty.

Doc from java.util.Hashtable.isEmpty.

Tests if this hashtable maps no keys to values.

Returns:boolean

true if this hashtable maps no keys to values; false otherwise.

Annotations

@Override

Overrides java.util.Properties.keys.

Doc from java.util.Hashtable.keys.

Returns an enumeration of the keys in this hashtable. Use the Enumeration methods on the returned object to fetch the keys sequentially. If the hashtable is structurally modified while enumerating over the keys then the results of enumerating are undefined.

Returns:Enumeration<Object>

an enumeration of the keys in this hashtable.

Annotations

@Override

Overrides java.util.Properties.keySet.

Implements java.util.Map.keySet.

Doc from java.util.Hashtable.keySet.

Returns a Set view of the keys contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not support the add or addAll operations.

Returns:Set<Object>

Doc from java.util.Map.keySet.

a set view of the keys contained in this map

Annotations

@Override

Overrides java.util.Properties.put.

Implements java.util.Map.put.

Doc from java.util.Hashtable.put.

Maps the specified key to the specified value in this hashtable. Neither the key nor the value can be null.

The value can be retrieved by calling the get method with a key that is equal to the original key.

Parameters

key:Object

the hashtable key

value:Object

the value

Returns:Object

the previous value of the specified key in this hashtable, or null if it did not have one

Annotations

@Override

Overrides java.util.Properties.putAll.

Implements java.util.Map.putAll.

Doc from java.util.Hashtable.putAll.

Copies all of the mappings from the specified map to this hashtable. These mappings will replace any mappings that this hashtable had for any of the keys currently in the specified map.

Parameters

t:Map<?, ?>

mappings to be stored in this map

Annotations

@Override

Overrides java.util.Properties.remove.

Implements java.util.Map.remove.

Doc from java.util.Hashtable.remove.

Removes the key (and its corresponding value) from this hashtable. This method does nothing if the key is not in the hashtable.

Parameters

key:Object

the key that needs to be removed

Returns:Object

the value to which the key had been mapped in this hashtable, or null if the key did not have a mapping

Annotations

@Override

Overrides java.util.Properties.setProperty.

Doc from java.util.Properties.setProperty.

Calls the Hashtable method put. Provided for parallelism with the getProperty method. Enforces use of strings for property keys and values. The value returned is the result of the Hashtable call to put.

Parameters

key:String

the key to be placed into this property list.

value:String

the value corresponding to key.

Returns:Object

the previous value of the specified key in this property list, or null if it did not have one.

Annotations

@Override

Overrides java.util.Properties.size.

Implements java.util.Map.size.

Doc from java.util.Hashtable.size.

Returns the number of keys in this hashtable.

Returns:int

the number of keys in this hashtable.

Annotations

@Override

Overrides java.util.Properties.toString.

Doc from java.util.Hashtable.toString.

Returns a string representation of this Hashtable object in the form of a set of entries, enclosed in braces and separated by the ASCII characters " , " (comma and space). Each entry is rendered as the key, an equals sign =, and the associated element, where the toString method is used to convert the key and element to strings.

Returns:String

a string representation of this hashtable

Annotations

@Override

Overrides java.util.Properties.values.

Implements java.util.Map.values.

Doc from java.util.Hashtable.values.

Returns a Collection view of the values contained in this map. The collection is backed by the map, so changes to the map are reflected in the collection, and vice-versa. If the map is modified while an iteration over the collection is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The collection supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Collection.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.

Returns:Collection<Object>

Doc from java.util.Map.values.

a collection view of the values contained in this map
