Detailed Description

This class gives an interface for the Interpreter to call into.

All its methods are pure virtuals so that it can be used in as many different class hierarchies as possible.


Member Function Documentation

virtual skExecutableIterator* skiExecutable::createIterator   [pure virtual]
 

This method returns an executable iterator used in foreach statements.

Returns:
an skExecutableIterator object that can be used to iterate over the components of this container

Reimplemented in skElementObject, skExecutable, skTreeNodeObject, and skXMLElementObject.

virtual skExecutableIterator* skiExecutable::createIterator const skString   qualifier [pure virtual]
 

This method returns an executable iterator used in foreach statements.

Parameters:
qualifier  a value to qualify the iteration by
Returns:
an skExecutableIterator object that can be used to iterate over the result of the qualifier

Reimplemented in skElementObject, skExecutable, skTreeNodeObject, and skXMLElementObject.

virtual int skiExecutable::executableType   const [pure virtual]
 

this method returns the type of the object.

Define your own value if you want to check the type of your object at run-time

Reimplemented in skElementObject, skExecutable, skTreeNodeObject, and skXMLElementObject.

virtual bool skiExecutable::getValue const skString   field_name,
const skString   attribute,
skRValue   value
[pure virtual]
 

requests the object to return a field's value.

Parameters:
field_name  - the name of the field name to get
attribute  - the attribute name to get (may be blank)
value  - the value to receive the value of the field
Returns:
true if the field was changed, false if the field could not be get or found

Reimplemented in skElementObject, skExecutable, skTreeNodeObject, and skXMLElementObject.

virtual bool skiExecutable::getValueAt const skRValue   array_index,
const skString   attribute,
skRValue   value
[pure virtual]
 

requests the object to return an object from its collection.

Parameters:
array_index  - the identifier of the item - this might be a string, integer or any other legal value
attribute  - the attribute name to get (may be blank)
value  - the value to receive the value of the field
Returns:
true if the field was changed, false if the field could not be get or found

Reimplemented in skElementObject, skExecutable, skTreeNodeObject, and skXMLElementObject.

virtual bool skiExecutable::method const skString   s,
skRValueArray   args,
skRValue   r
[pure virtual]
 

Requests that the object execute the given method.

Parameters:
method_name  - the name of the method to execute
arguments  - an array of RValue objects, which are the arguments to the method
return_value  - an object to receive the return value of the method
return  true if the method could be executed, or false if the method is not supported

Reimplemented in skElementObject, skElementObjectEnumerator, skExecutable, skTreeNodeObject, skTreeNodeObjectEnumerator, skXMLElementObject, and skXMLElementObjectEnumerator.

virtual bool skiExecutable::setValue const skString   field_name,
const skString   attribute,
const skRValue   value
[pure virtual]
 

requests the object to set a field to the given value.

Parameters:
field_name  - the name of the field name to set
attribute  - the attribute name to set (may be blank)
value  - the value to be set
Returns:
true if the field was changed, false if the field could not be set or found

Reimplemented in skElementObject, skExecutable, skInterpreter, skTreeNodeObject, and skXMLElementObject.

virtual bool skiExecutable::setValueAt const skRValue   array_index,
const skString   attribute,
const skRValue   value
[pure virtual]
 

requests the object to set an item in its collection to a certain value.

Parameters:
array_index  - the identifier of the item - this might be a string, integer or any other legal value
attribute  - the attribute name to set (may be blank)
value  - the value to be set
Returns:
true if the field was changed, false if the field could not be set or found

Reimplemented in skElementObject, skExecutable, skTreeNodeObject, and skXMLElementObject.
