Method Detail

start

public void start()

Initialise the MBean

stop

public void stop()

Unregister all MBeans representing objects in the ObjectStore represented by this MBean

setTypes

@Deprecated
public void setTypes(java.util.Map<java.lang.String,java.lang.String> types)

Deprecated.

This method is deprecated in favour of @setType The issue with this method is there is no mechanism for determining which class is responsible for a given OS type. Define which object store types will registered as MBeans

Parameters:

types - the list of ObjectStore types that can be represented as MBeans

setType

public boolean setType(java.lang.String osTypeClassName,
              java.lang.String beanTypeClassName)

Tell the browser which beans to use for particular Object Store Action type

Parameters:

osTypeClassName -

beanTypeClassName -

Returns:

dump

public java.lang.StringBuilder dump(java.lang.StringBuilder sb)

findUid

public UidWrapper findUid(Uid uid)

See if the given uid has previously been registered as an MBean

Parameters:

uid - the unique id representing an ObjectStore entry

Returns:

the MBean wrapper corresponding to the requested Uid (or null if it hasn't been registered)

findUid

public UidWrapper findUid(java.lang.String uid)

probe

public void probe()

See if any new MBeans need to be registered or if any existing MBeans no longer exist as ObjectStore entries.

Specified by:

probe in interface ObjStoreBrowserMBean

viewSubordinateAtomicActions

public void viewSubordinateAtomicActions(boolean enable)

Specified by:

viewSubordinateAtomicActions in interface ObjStoreBrowserMBean

probe

public java.util.List<UidWrapper> probe(java.lang.String type,
                               java.lang.String beantype)

Register new MBeans of the requested type (or unregister ones whose corresponding ObjectStore entry has been removed)

Parameters:

type - the ObjectStore entry type

beantype - the class name of the MBean implementation used to represent the request type

Returns:

the list of MBeans representing the requested ObjectStore type
