Method Detail

registerComponent

public void registerComponent(Component component,
                              ComponentName name)
                       throws ComponentAlreadyExistsException

ComponentAlreadyExistsException

unregisterMBean

public void unregisterMBean(ComponentName name)
                     throws ComponentNotFoundException

ComponentNotFoundException

get

public ComponentEntry get(ComponentName name)
                   throws ComponentNotFoundException

ComponentNotFoundException

getDefaultDomain

public java.lang.String getDefaultDomain()

getObjectInstance

public Node getObjectInstance(ComponentName name)
                       throws ComponentNotFoundException

ComponentNotFoundException

contains

public boolean contains(ComponentName name)

getSize

public int getSize()

findEntries

public java.util.List findEntries(ComponentName pattern)

domainMatches

protected boolean domainMatches(java.lang.String src,
                                java.lang.String pat)

Compare the src and pat strings where ? and * chars are significant.

domainMatches

protected boolean domainMatches(char[] src,
                                int spos,
                                char[] pat,
                                int ppos)

Compare the src and pat char arrays where ? and * chars are significant. I arrived at this solution after quite a bit of trial and error - it's all a bit interwoven. Obviously I'm no good at parsers and there must be a clearer or more elegant way to do this. I'm suitably in awe of the perl regex hackers now.
