Member Function Documentation

skExecutableIterator * skExecutable::createIterator ( ) [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 from skiExecutable.

Reimplemented in skTest, skElementObject, skTreeNodeObject, and skXMLElementObject.

skExecutableIterator * skExecutable::createIterator ( const skString & qualifier ) [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 from skiExecutable.

Reimplemented in skTest, skElementObject, skTreeNodeObject, and skXMLElementObject.

bool skExecutable::equals ( const skiExecutable * other_object ) const [virtual]
 

This method compares this object with another object.

This implementation checks object pointers.

Reimplemented from skiExecutable.

int skExecutable::executableType ( ) const [virtual]
 

this method returns the type of the object at this level this is UNDEFINED_TYPE.

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

Reimplemented from skiExecutable.

Reimplemented in skElementObject, skTreeNodeObject, and skXMLElementObject.

bool skExecutable::getValue ( const skString & s,
const skString & attribute,
skRValue & return_value ) [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 from skiExecutable.

Reimplemented in skTest, skElementObject, skTreeNodeObject, and skXMLElementObject.

bool skExecutable::getValueAt ( const skRValue & array_index,
const skString & attribute,
skRValue & value ) [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 from skiExecutable.

Reimplemented in skTest, skElementObject, skTreeNodeObject, and skXMLElementObject.

bool skExecutable::method ( const skString & name,
skRValueArray & args,
skRValue & ret ) [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 from skiExecutable.

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

bool skExecutable::setValue ( const skString & s,
const skString & attribute,
const skRValue & return_value ) [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 from skiExecutable.

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

bool skExecutable::setValueAt ( const skRValue & array_index,
const skString & attribute,
const skRValue & value ) [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
