METHOD_INJECTION

public static final Properties METHOD_INJECTION

Turns on Method Injection.

NO_CACHE

public static final Properties NO_CACHE

Turns off Caching of component instances. (Often referred to in other circles as singleton).

CACHE

public static final Properties CACHE

Turns on Caching of component instances. (Often referred to in other circles as singleton)

SYNCHRONIZE

public static final Properties SYNCHRONIZE

Turns on synchronized access to the component instance. (Under JDK 1.5 conditions, it will be better to use LOCK instead.

Synchronizing

NO_SYNCHRONIZE

public static final Properties NO_SYNCHRONIZE

Turns off synchronized access to the component instance.

LOCK

public static final Properties LOCK

Uses a java.util.concurrent.Lock to provide faster access than synchronized.

HIDE_IMPL

public static final Properties HIDE_IMPL

Turns on implementation hiding. You may use the JDK Proxy implementation included in this version, or the ASM-based implementation hiding method included in PicoContainer Gems. However, you cannot use both in a single PicoContainer instance.

NO_HIDE_IMPL

public static final Properties NO_HIDE_IMPL

Turns off implementation hiding.

immutable

public static Properties immutable(String name,
                   String value)

Transforms a single name value pair unto a read only Properties instance.

Example Usage:

                Properties readOnly = immutable("oneKey","oneValue"};
                assert readOnly.getProperty("oneKey") != null);
 

Parameters:

name - the property key.

value - the property value.

Returns:

Read Only properties instance.
