```
Holds meta information useful in generating and/or supplementing the default MBeanInfo as well as other runtime fields or optimizations. Depending on how the implementor generates MBeans, not all of this information is necessarily used; it could be ignored if there is a more authoritative source (eg internal @Configured interfaces that also have AMXConfig proxy interfaces).
In general, this annotation is used only by amx-core, amx-config and related built-in AMX modules.

Optional Elements
Modifier and Type	Optional Element	Description
`boolean`	`globalSingleton`	if true, the MBean is a global singleton, unique in type among all AMX MBeans.
`boolean`	`immutableMBeanInfo`	If true, states that the MBeanInfo is immutable; that once MBeanInfo is obtained it may be cached, avoiding needless/repeated invocations of getMBeanInfo().
`boolean`	`leaf`	If true, no children are allowed.
`boolean`	`singleton`	if true, the MBean is a singleon within its parent's scope
`String`	`type`	overrides default type to be used in ObjectName=, ignored if null or empty

boolean immutableMBeanInfo
```
    If true, states that the MBeanInfo is immutable; that once MBeanInfo is obtained it may be cached, avoiding needless/repeated invocations of getMBeanInfo(). Very few MBeans have mutable MBeanInfo, so this defaults to 'true'. The term is a misnomer; it should be invariantMBeanInfo(), but this name is used go be consistent with the JMX standard.

    true

    overrides default type to be used in ObjectName=, ignored if null or empty

    if true, the MBean is a singleon within its parent's scope
    
    Default:
    
    false
- - globalSingleton
```
boolean globalSingleton
```
    if true, the MBean is a global singleton, unique in type among all AMX MBeans. Being a globalSingleton implies being a singleton
    
    Default:
    
    false
