All known Subclasses:   com.sun.midp.installer.JadProperties,
Properties
public class Properties (Code)
The Properties class represents a persistent set of properties. Each key and its corresponding value in the property list is a string.




Constructor Summary
public  Properties()
     Constructor - creates an empty property list.
public  Properties(String[] propertyStrings)
     Constructor - creates an populated property list.

Method Summary
public synchronized  voidaddProperty(String key, String value)
     Store multiple key:value pair.
public  StringgetKeyAt(int index)
     Gets a property key by index.
public  StringgetProperty(String key)
     Searches for the property with the specified key in this property list. The method returns null if the property is not found.
Parameters:
  key - the property key.
public  StringgetPropertyIgnoreCase(String key)
     This method is very similar to getproperty() except with a difference that the keys are searched in case-insensitive manner.
public  StringgetValueAt(int index)
     Gets a property value by index.
public synchronized  StringremoveProperty(String key)
     Removes a property (key:value pair) from the property list based on the key string.
Parameters:
  key - the key to be removed from the property list.
public synchronized  StringsetProperty(String key, String value)
     Store a single key:value pair.
public synchronized  StringsetPropertyAt(int index, String value)
     Replace the value of the property at the given index.
Parameters:
  index - 0 based index of a property
Parameters:
  value - the new value for the property at index.
public synchronized  StringsetPropertyIgnoreCase(String key, String value)
     Store a single key:value pair.
public  intsize()
     Gets the number of properties.


Constructor Detail
Properties
public Properties()(Code)
Constructor - creates an empty property list.



Properties
public Properties(String[] propertyStrings)(Code)
Constructor - creates an populated property list.
Parameters:
  propertyStrings - an array of Strings 2 per property, will befilled in with a pair pattern of key and value, this exact arraywill be used for property lookup (the array will not be changed).No other allocation will be done until the array is changed and atthat time the initial property array will be released.




Method Detail
addProperty
public synchronized void addProperty(String key, String value)(Code)
Store multiple key:value pair. Provided for parallelism with the getProperty method. Enforces use of strings for property keys and values.
Parameters:
  key - the key to be placed into this property list.
Parameters:
  value - the value corresponding to key.
See Also:   Properties.getProperty



getKeyAt
public String getKeyAt(int index)(Code)
Gets a property key by index. Used by the JadWriter as part of the JAD Tool.
Parameters:
  index - 0 based index of a property the key of the property with the specified index.
exception:
  ArrayIndexOutOfBoundsException - if an invalid index was given.



getProperty
public String getProperty(String key)(Code)
Searches for the property with the specified key in this property list. The method returns null if the property is not found.
Parameters:
  key - the property key. the value in this property list with the specified key value.
exception:
  NullPointerException - is thrown if key is null.
See Also:   Properties.setProperty
See Also:   Properties.removeProperty



getPropertyIgnoreCase
public String getPropertyIgnoreCase(String key)(Code)
This method is very similar to getproperty() except with a difference that the keys are searched in case-insensitive manner. This is needed in certain situations like HTTP header names.
Parameters:
  key - the property key. the value in this property list with the specified key value.
exception:
  NullPointerException - is thrown if key is null.
See Also:   Properties.setProperty
See Also:   Properties.removeProperty



getValueAt
public String getValueAt(int index)(Code)
Gets a property value by index. Used by the JadWriter as part of the JAD Tool.
Parameters:
  index - 0 based index of a property the value of the property with the specified index.
exception:
  ArrayIndexOutOfBoundsException - if an invalid index was given.



removeProperty
public synchronized String removeProperty(String key)(Code)
Removes a property (key:value pair) from the property list based on the key string.
Parameters:
  key - the key to be removed from the property list. the element associated with the key.
See Also:   Properties.setProperty
See Also:   Properties.getProperty



setProperty
public synchronized String setProperty(String key, String value)(Code)
Store a single key:value pair. Provided for parallelism with the getProperty method. Enforces use of strings for property keys and values. If a key already exists in storage, the value corresponding to that key will be replaced and returned.
Parameters:
  key - the key to be placed into this property list.
Parameters:
  value - the value corresponding to key. if the new property value replaces an existing one, the old value is returned. otherwise, null is returned.
See Also:   Properties.getProperty
See Also:   Properties.removeProperty



setPropertyAt
public synchronized String setPropertyAt(int index, String value)(Code)
Replace the value of the property at the given index.
Parameters:
  index - 0 based index of a property

  value - the new value for the property at index. previous value
exception:
  IndexOutOfBoundsException - if the index is out of bounds



setPropertyIgnoreCase
public synchronized String setPropertyIgnoreCase(String key, String value)(Code)
