public JigsawHttpSession(JigsawHttpSessionContext context,
javax.servlet.http.Cookie cookie)
getId
public java.lang.String getId()
- Returns the identifier assigned to this session. An HttpSession's
identifier is a unique string that is created and maintained by
HttpSessionContext.
- Specified by:
- getId in interface javax.servlet.http.HttpSession
- Returns:
- the identifier assigned to this session
- Throws:
- java.lang.IllegalStateException - if an attempt is made to access
session data after the session has been invalidated
getSessionContext
public javax.servlet.http.HttpSessionContext getSessionContext()
- Deprecated. since jsdk2.1
- Returns the context in which this session is bound.
- Specified by:
- getSessionContext in interface javax.servlet.http.HttpSession
- Returns:
- the context in which this session is bound.
- Throws:
- java.lang.IllegalStateException - if an attempt is made to access
session data after the session has been invalidated
getCreationTime
public long getCreationTime()
- Returns the time at which this session representation was created,
in milliseconds since midnight, January 1, 1970 UTC.
- Specified by:
- getCreationTime in interface javax.servlet.http.HttpSession
- Returns:
- the time when the session was created
- Throws:
- java.lang.IllegalStateException - if an attempt is made to access
session data after the session has been invalidated
getLastAccessedTime
public long getLastAccessedTime()
- Returns the last time the client sent a request carrying the identifier
assigned to the session. Time is expressed as milliseconds
since midnight, January 1, 1970 UTC. Application level operations,
such as getting or setting a value associated with the session,
does not affect the access time.
- Specified by:
- getLastAccessedTime in interface javax.servlet.http.HttpSession
- Returns:
- the last time the client sent a request carrying the identifier
assigned to the session
- Throws:
- java.lang.IllegalStateException - if an attempt is made to access
session data after the session has been invalidated
setLastAccessedTime
protected void setLastAccessedTime()
invalidate
public void invalidate()
- Causes this representation of the session to be invalidated and removed
from its context.
- Specified by:
- invalidate in interface javax.servlet.http.HttpSession
- Throws:
- java.lang.IllegalStateException - if an attempt is made to access
session data after the session has been invalidated
getValue
public java.lang.Object getValue(java.lang.String name)
- Returns the object bound to the given name in the session's application
layer data. Returns null if there is no such binding.
- Specified by:
- getValue in interface javax.servlet.http.HttpSession
- Parameters:
name
- - the name of the binding to find- Returns:
- the value bound to that name, or null if the binding does
not exist.
- Throws:
- java.lang.IllegalStateException - if an attempt is made to access
session data after the session has been invalidated
putValue
public void putValue(java.lang.String name,
java.lang.Object value)
- Binds the specified object into the session's application layer data
with the given name. Any existing binding with the same name
is replaced. New (or existing) values that implement the
HttpSessionBindingListener interface will call its valueBound() method.
- Specified by:
- putValue in interface javax.servlet.http.HttpSession
- Parameters:
name
- - the name to which the data object will be bound.
This parameter cannot be null.value
- - the data object to be bound. This parameter cannot
be null.- Throws:
- java.lang.IllegalStateException - if an attempt is made to access
session data after the session has been invalidated
removeValue
public void removeValue(java.lang.String name)
- Removes the object bound to the given name in the session's application
layer data. Does nothing if there is no object bound to the
given name. The value that implements the HttpSessionBindingListener
interface will call its valueUnbound() method.
- Specified by:
- removeValue in interface javax.servlet.http.HttpSession
- Parameters:
name
- - the name of the object to remove- Throws:
- java.lang.IllegalStateException - if an attempt is made to access
session data after the session has been invalidated
valueBound
protected void valueBound(javax.servlet.http.HttpSessionBindingListener value,
java.lang.String name)
valueUnbound
protected void valueUnbound(javax.servlet.http.HttpSessionBindingListener value,
java.lang.String name)
getValueNames
public java.lang.String[] getValueNames()
- Returns an array of the names of all the application layer data objects
bound into the session. For example, if you want to delete
all of the data objects bound into the session, use this method to
obtain their names.
- Specified by:
- getValueNames in interface javax.servlet.http.HttpSession
- Returns:
- an array containing the names of all of the application layer
data objects bound into the session
- Throws:
- java.lang.IllegalStateException - if an attempt is made to access
session data after the session has been invalidated
isNew
public boolean isNew()
- A session is considered to be "new" if it has been created by the
server, but the client has not yet acknowledged joining the
session. For example, if the server supported only cookie-based
sessions and the client had completely disabled the use of
cookies, then calls to HttpServletRequest.getSession() would always
return "new" sessions.
- Specified by:
- isNew in interface javax.servlet.http.HttpSession
- Returns:
- true if the session has been created by the server but the
client has not yet acknowledged joining the session; false otherwise
- Throws:
- java.lang.IllegalStateException - if an attempt is made to access
session data after the session has been invalidated
setNoMoreNew
protected void setNoMoreNew()
isValid
protected boolean isValid()
getCookie
protected javax.servlet.http.Cookie getCookie()

public void setMaxInactiveInterval(int interval)
- Specified by:
- setMaxInactiveInterval in interface javax.servlet.http.HttpSession
getMaxInactiveInterval
public int getMaxInactiveInterval()
- Specified by:
