setIsolateId

getName

public String getName()

createPseudoVariables

public void createPseudoVariables(boolean oui)

Description copied from interface: Context

Enables/disables the creation of variables during lookup calls. This is ONLY used by AssignmentExp for creating a assigning a value to a property which currently does not exist.

Specified by:

createPseudoVariables in interface Context

createContext

public Context createContext(Object o)

Description copied from interface: Context

Creates a new context object by combining the current one and o. For example, if the user typed "myVariable.myMember", then this function will get called with o equal to the object which represents "myVariable". This function should return a new context which, when called with lookup("myMember"), will return an object for that member.

Specified by:

createContext in interface Context

Parameters:

o - any object which may have been returned by this class's lookup() function

assign

public void assign(Object o,
          Value v)
            throws NoSuchVariableException,
                   PlayerFaultException

Description copied from interface: Context

Assign the object o, the value v.

Specified by:

assign in interface Context

Parameters:

o - a variable to assign to -- this should be some value returned by an earlier call to lookup().

v - a value, such as a Boolean, Long, String, etc.

Throws:

NoSuchVariableException

PlayerFaultException

lookup

public Object lookup(Object o)
              throws NoSuchVariableException,
                     PlayerFaultException

The Context interface which goes out and gets values from the session Expressions use this interface as a means of evaluation. We also use this to create a reference to internal variables.

Specified by:

lookup in interface Context

Parameters:

o - the object to look up; most commonly a string representing the name of a member variable.

Throws:

NoSuchVariableException

PlayerFaultException

lookupMembers

public Object lookupMembers(Object o)
                     throws NoSuchVariableException

Description copied from interface: Context

Looks for the members of an object.

Specified by:

lookupMembers in interface Context

Parameters:

o - A variable whose members we want to look up

Returns:

Some object which represents the members; could even be just a string. See lookup() for more information about the returned type.

Throws:

NoSuchVariableException

See Also:

Context.lookup(Object)

toValue

public Value toValue(Object o)

Description copied from interface: Context

Converts the object to a Value.

Specified by:

toValue in interface Context

Parameters:

o - Either object that was returned by an earlier call to lookup(), or one of the raw types that can be returned by Value.getValueAsObject().

Returns:

the corresponding Value, or null.

See Also:

Value.getValueAsObject()

toValue

public Value toValue()

Description copied from interface: Context

Converts the context to a Value. Very similar to toValue(Object o), except that the object being converted is the object that was used to initialize this context.

Specified by:

toValue in interface Context

Returns:

the corresponding Value, or null.

getSession

public Session getSession()

Description copied from interface: Context

Returns the session associated with this context, or null. This can legitimately be null; for example, in fdb, you are allowed to do things like "set $columnwidth = 120" before beginning a debugging session.

Specified by:

getSession in interface Context

getIsolateId

public int getIsolateId()

Description copied from interface: Context

The worker id to which this context object belongs.

Specified by:

getIsolateId in interface Context
