Method Detail

init

public void init(STosClass tosClass,
                 SContext context,
                 java.lang.Object[] constructorArgs)
          throws STeaException

Description copied from interface: STosObj

Initializes the object internal state.

Specified by:

init in interface STosObj

Parameters:

tosClass - The TOS class the TOS object belong to.

context - The context where the TOS object is being instantiated.

constructorArgs - The arguments to pass the constructor of this TOS object.

Throws:

STeaException

getMembers

public SContext getMembers(int level)

Description copied from interface: STosObj

Fetches the members for this TOS object corresponding to a given TOS class in the TOS object class hierarchy. The returned SContext has no parent.

Specified by:

getMembers in interface STosObj

Parameters:

level - Identifies the TOS class in the TOS object class hierarchy of this TOS object. A value of zero means the root class in the hierarchy.

Returns:

The set of members (names and values) for this object related to a specific TOS class.

getTosClass

public STosClass getTosClass()

Retrieves the class object this TOS object is an instance of.

Specified by:

getTosClass in interface STosObj

Returns:

The STosClass object this TOS object is an instance of.

exec

public java.lang.Object exec(SObjFunction obj,
                             SContext context,
                             java.lang.Object[] args)
                      throws STeaException

This is the dispatch method. It will call the TOS method of this TOS object. The TOS method is specified by the first argument to the Tea command this object implements. So, args[0] is a reference to this Java object, args[1] is a symbol that references the TOS method to be called, the remaining arguments are passed to the TOS method.

A TOS method is implemented by an STosMethod object.

Specified by:

exec in interface SObjFunction

Parameters:

context - The context inside which this command was invoked.

args - The array of arguments passed to the command.

obj - The SObjFunction that led to call this function. Most of the time is the same as the this object.

Returns:

The object returned by the execution of the method.

Throws:

com.pdmfc.tea.runtime.STException - Only thrown by the execution of the method.

STeaException - Thrown if there were problems executing the command.
