Parameters:

aSystemLog - SystemLog

Method Detail

getType

public String getType()

Reads attribute "Type".

getType() and getId() are used in a common schema for object names for all MBeans in the management package. The key properties part of the object name of each MBean is defined as "type=" + getType() + ",id=" + getId(), for example "type=AssemblyLine,id=Hello".

Specified by:

getType in interface BaseMBean

Returns:

the type of this MBean.

getId

public String getId()

Reads attribute "Id". The "Id" value should be different for different MBeans of the same type.

getType() and getId() are used in a common schema for object names for all MBeans in the management package. The key properties part of the object name of each MBean is defined as "type=" + getType() + ",id=" + getId(), for example "type=AssemblyLine,id=Hello".

Specified by:

getId in interface BaseMBean

Returns:

the Id of this MBean.
