Creates a new properties object.

Method Summary

void
clear()
Removes all properties from this object.
Object
clone()
Creates a copy of this properties object.
boolean
containsKey(String key)
Tests if this object contains a given property name.
boolean
containsValue(String value)
Tests if this object contains a given property value.
void
decode(DataInputStream in)
Decodes a set of properties from the given input stream.
void
encode(DataOutputStream out)
Encodes this set of properties to the given output stream.
String
get(String key)
Returns the value mapped by the given key, or null if there is no such mapping.
String
put(String key, String value)
Adds a new property to this object.
String

Constructor Details

Properties

public Properties()
Creates a new properties object.

Method Details

clear

public void clear()
Removes all properties from this object.

clone

public Object clone()
Creates a copy of this properties object.
Overrides:
clone in interface Object
Returns:
The copy.

containsKey

public boolean containsKey(String key)
Tests if this object contains a given property name.
Parameters:
key - The key to test.
Returns:
True if this object contains the given key.

containsValue

public boolean containsValue(String value)
Tests if this object contains a given property value.
Parameters:
value - The value to test.
Returns:
True if this object contains the given value.

decode

public void decode(DataInputStream in)
            throws IOException
Decodes a set of properties from the given input stream.
Parameters:
in - The input stream.
Throws:
IOException - If an I/O error occurs.

encode

public void encode(DataOutputStream out)
            throws IOException
Encodes this set of properties to the given output stream.
Parameters:
out - The output stream to encode to.
Throws:
IOException - If an I/O error occurs.

get

public String get(String key)
Returns the value mapped by the given key, or null if there is no such mapping.
Parameters:
key -

put

public String put(String key,
                  String value)
Adds a new property to this object.
Parameters:
key - The key, which can neither be null nor empty.
value - The value, which cannot be null.
Returns:
The old value mapped by the key, if any.
Throws:
IllegalArgumentException - If either the key or value parameter is null, or if the key is empty.

remove

public String remove(String key)
Removes a key and its value from this object.
Parameters:
key - The key of the property to remove.
Returns:
The old value mapped by the key, if any.

toString

public String toString()
Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() and such.

It is typical, but not required, to ensure that this method never completes abruptly with a RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

Overrides:
toString in interface Object
Returns:
the String representing this Object, which may be null
See Also:
getClass(), Object.hashCode(), Class.getName(), Integer.toHexString(int)
