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(Map<String,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(String osTypeClassName,
              String beanTypeClassName)

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

Parameters:

osTypeClassName -

beanTypeClassName -

Returns:

dump

public StringBuilder dump(StringBuilder sb)

Dump info about all registered MBeans

Parameters:

sb - a buffer to contain the result

Returns:

the passed in buffer

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

@Deprecated
public UidWrapper findUid(String uid)

Deprecated. use findUid(com.arjuna.ats.arjuna.common.Uid) ()} instead.
