Constructor Detail

SessionName

public SessionName(Global glob,
                   java.lang.String name)

Create and parse a unified name.

Parameters:

name - Examples:

  /node/heron/client/joe/2
  client/joe/2
  joe/2
  joe

  /node/heron/client/joe/session/2
  client/joe/session/2
  joe/session/2
 

Throws:

java.lang.IllegalArgumentException - if your name can't be parsed

SessionName

public SessionName(Global glob,
                   NodeId nodeId,
                   java.lang.String subjectId,
                   long pubSessionId)

SessionName

public SessionName(Global glob,
                   NodeId nodeId,
                   java.lang.String name)

Parameters:

nodeId - if not null it has precedence to the nodeId which is probably found in name

name - Examples:

  /node/heron/client/joe/2
  client/joe/2
  joe/2
  joe
 

The EventPlugin supports wildcard '*' as sessionNumber, to be able to use this parser we map it to Long.MIN_VALUE

Throws:

java.lang.IllegalArgumentException - if your name can't be parsed

SessionName

public SessionName(Global glob,
                   SessionName sessionName,
                   long pubSessionId)

Create a new instance based on the given sessionName but with added/changed pubSessionId

Method Detail

public final boolean isCoreInternalLoginName()

getPublicSessionId

public long getPublicSessionId()

Returns:

The public session identifier e.g. "2" or 0 if in subject context

isSession

public boolean isSession()

Check if we hold a session or a subject

isPubSessionIdInternal

public boolean isPubSessionIdInternal()

Returns:

true it publicSessionId is given by xmlBlaster server (if < 0)

isPubSessionIdUser

public boolean isPubSessionIdUser()

Returns:

true it publicSessionId is given by user/client (if > 0)

equalsRelative

matchRelativeName

public boolean matchRelativeName(java.lang.String pattern)

Check matching name, the subjectId or pubSessionId can be a wildcard "*" (note: no blanks in the example below are allowed, we need to write it like this to distinguish it from a java comment)

Parameters:

pattern - for example "client/ * /session/ *", ""client/ * /session/1", "client/joe/session/ *", "client/joe/session/1"

Returns:

true if wildcard matches or exact match

getRelativeSubjectIdWildcard

public java.lang.String getRelativeSubjectIdWildcard()

Note: no blanks in the example below are allowed, we need to write it like this to distinguish it from a java comment

Returns:

e.g. "client/ * /session/2"

getRelativePubSessionIdWildcard

public java.lang.String getRelativePubSessionIdWildcard()

Note: no blanks in the example below are allowed, we need to write it like this to distinguish it from a java comment

Returns:

e.g. "client/joe/session/ *

getRelativeWildcard

public java.lang.String getRelativeWildcard()

Note: no blanks in the example below are allowed, we need to write it like this to distinguish it from a java comment

Returns:

"client/* /session/*

toXml

public final java.lang.String toXml()

Returns:

internal state of SessionName as a XML ASCII string

toXml

public final java.lang.String toXml(java.lang.String extraOffset)

Dump state of this object into a XML ASCII string.

Parameters:

extraOffset - indenting of tags for nice output

Returns:

internal state of SessionName as a XML ASCII string

main

public static void main(java.lang.String[] args)

Method for testing only.

Invoke: java -Djava.compiler= org.xmlBlaster.util.SessionName -name client/jack/1
