Method Detail

getCreationTime

public long getCreationTime()

Description copied from interface: Session

Returns the time when this session was created, measured in milliseconds since midnight January 1, 1970 GMT.

Specified by:

getCreationTime in interface Session

Following copied from interface: org.apache.cocoon.environment.Session

Returns:

a long specifying when this session was created, expressed in milliseconds since 1/1/1970 GMT

Throws:

java.lang.IllegalStateException - if this method is called on an invalidated session

getId

public java.lang.String getId()

Description copied from interface: Session

Returns a string containing the unique identifier assigned to this session. The identifier is assigned by the context container and is implementation dependent.

Specified by:

getId in interface Session

Following copied from interface: org.apache.cocoon.environment.Session

Returns:

a string specifying the identifier assigned to this session

Throws:

java.lang.IllegalStateException - if this method is called on an invalidated session

getLastAccessedTime

public long getLastAccessedTime()

Description copied from interface: Session

Returns the last time the client sent a request associated with this session, as the number of milliseconds since midnight January 1, 1970 GMT.

Actions that your application takes, such as getting or setting a value associated with the session, do not affect the access time.

Specified by:

getLastAccessedTime in interface Session

Following copied from interface: org.apache.cocoon.environment.Session

Returns:

a long representing the last time the client sent a request associated with this session, expressed in milliseconds since 1/1/1970 GMT

Throws:

java.lang.IllegalStateException - if this method is called on an invalidated session

setMaxInactiveInterval

public void setMaxInactiveInterval(int interval)

Description copied from interface: Session

Specifies the time, in seconds, between client requests before the contextcontainer will invalidate this session. A negative time indicates the session should never timeout.

Specified by:

setMaxInactiveInterval in interface Session

Following copied from interface: org.apache.cocoon.environment.Session

Parameters:

interval - An integer specifying the number of seconds

getMaxInactiveInterval

public int getMaxInactiveInterval()

Description copied from interface: Session

Returns the maximum time interval, in seconds, that the context container will keep this session open between client accesses. After this interval, the context container will invalidate the session. The maximum time interval can be set with the setMaxInactiveInterval method. A negative time indicates the session should never timeout.

Specified by:

getMaxInactiveInterval in interface Session

Following copied from interface: org.apache.cocoon.environment.Session

Returns:

an integer specifying the number of seconds this session remains open between client requests
