Method Detail

getSuperClass

public STosClass getSuperClass()

Description copied from interface: STosClass

Retrieves the TOS base class of this TOS class.

Specified by:

getSuperClass in interface STosClass

Returns:

The null value, meaning this TOS class has no base class.

getMemberNames

public SObjSymbol[] getMemberNames()

Fetches the member names for this TOS class. It has no members, so it just returns an empty array of member names.

Specified by:

getMemberNames in interface STosClass

Returns:

An empty array, meaning this TOS class does not define any members.

setConstructor

public void setConstructor(STosMethod method)

Specifies the constructor for this TOS class.

Specified by:

setConstructor in interface STosClass

Parameters:

method - A reference to the SObjFunction object that implements the TOS method.

getConstructor

public STosMethod getConstructor()

Description copied from interface: STosClass

Fetches the constructor method for this TOS class.

Specified by:

getConstructor in interface STosClass

Returns:

The STosMethod object corresponding to the constructor method for this TOS class. The null object is returned if this TOS class has no constructor.

addMethod

public void addMethod(SObjSymbol methodName,
                      STosMethod method)

Associates a new TOS method with this TOS class. If a method with the same name already existed then it is superceded by this new method.

Specified by:

addMethod in interface STosClass

Parameters:

methodName - A symbol standing for the name of the method being defined.

method - A reference to the SObjFunction object that implements the TOS method.

getMethod

public STosMethod getMethod(SObjSymbol methodName)
                     throws SNoSuchMethodException

Fecthes the named method.

Specified by:

getMethod in interface STosClass

Returns:

The STosMethod of this TOS class named methodName.

Throws:

SNoSuchMethodException - Thrown if there is no name in this tos class named methodName.

getMethods

public java.util.Iterator getMethods()

Description copied from interface: STosClass

Fetches all the methods this TOS class implements. These methods will include all the methods of the base classes.

Specified by:

getMethods in interface STosClass

Returns:

A java.util.Iterator containing the all the STosMethods associated with this TOS class.

newInstance

public STosObj newInstance(SContext context,
                           java.lang.Object[] args)
                    throws STeaException

Description copied from interface: STosClass

Creates a new instance of an object of this TOS class.

Specified by:

newInstance in interface STosClass

Returns:

A new STosObj object, representing a new instance of this TOS class.

Throws:

STeaException - Throw if there were any problems instantiating the new object.

getName

public java.lang.String getName()

Description copied from interface: STosClass

Fetches the name associated with this TOS class.

Specified by:

getName in interface STosClass

Returns:
