## Member Function Documentation

virtual const XObjectPtr XObjectFactory::createBoolean | ( | bool | theValue | ) | `[pure virtual]`

  | Create a boolean XObject from a boolean value. Parameters:
  theValue | value used to create object
Returns: pointer to new object Implemented in XObjectFactoryDefault.

virtual const XObjectPtr XObjectFactory::createNodeSet | ( | XalanNode * | theValue | ) | `[pure virtual]`

  | Create a node set XObject from a node. Parameters:
  theNOde | value used to create object.
Returns: pointer to new object Implemented in XObjectFactoryDefault.

virtual const XObjectPtr XObjectFactory::createNodeSet | ( | BorrowReturnMutableNodeRefList & | theValue | ) | `[pure virtual]`

  | Create a node set XObject from a node list. Parameters:
  theValue | value used to create object. theValue will be owned by the new XObject.
Returns: pointer to new object Implemented in XObjectFactoryDefault.

virtual const XObjectPtr XObjectFactory::createNull | ( |  | ) | `[pure virtual]`

  | Create a null XObject. Parameters:
  theValue | value used to create object
Returns: pointer to new object Implemented in XObjectFactoryDefault.

virtual const XObjectPtr XObjectFactory::createNumber | ( | const XToken & | theValue | ) | `[pure virtual]`

  | Create a numeric XObject from an XToken. The XToken instance must be inexistence for the lifetime of the object. Parameters:
  theValue | value used to create object
Returns: pointer to new object Implemented in XObjectFactoryDefault.

virtual const XObjectPtr XObjectFactory::createNumber | ( | double | theValue | ) | `[pure virtual]`

  | Create a numeric XObject from a number. Parameters:
  theValue | value used to create object
Returns: pointer to new object Implemented in XObjectFactoryDefault.

virtual const XObjectPtr XObjectFactory::createString | ( | GetAndReleaseCachedString & | theValue | ) | `[pure virtual]`

  | Create a string XObject from a cached XalanDOMString,. Parameters:
  theValue | value used to create object
Returns: pointer to new object Implemented in XObjectFactoryDefault.

virtual const XObjectPtr XObjectFactory::createString | ( | const XToken & | theValue | ) | `[pure virtual]`

  | Create a string XObject from an XToken. The XToken instance must be inexistence for the lifetime of the object. Parameters:
  theValue | value used to create object
Returns: pointer to new object Implemented in XObjectFactoryDefault.

virtual const XObjectPtr XObjectFactory::createString | ( | const XalanDOMChar * | theValue,

  | Create a string XObject from an array of characters. Parameters:
  theValue | a pointer to the array theLength the length of the array
Returns: pointer to new object Implemented in XObjectFactoryDefault.

virtual const XObjectPtr XObjectFactory::createString | ( | const XalanDOMChar * | theValue | ) | `[pure virtual]`

  | Create a string XObject from a null-terminated array of characters. Parameters:

Returns: pointer to new object Implemented in XObjectFactoryDefault.

virtual const XObjectPtr XObjectFactory::createStringReference | ( | const XalanDOMString & | theValue | ) | `[pure virtual]`

  | Create a string XObject from a string. The XObject will hold a reference to the supplied string, so the string must be in scope for the lifetime of the instance Parameters:

virtual const XObjectPtr XObjectFactory::createUnknown | ( | const XalanDOMString & | theValue | ) | `[pure virtual]`

  | Create an "unknown" XObject from a string. Parameters:
  theValue | value used to create object
Returns: pointer to new object Implemented in XObjectFactoryDefault.

void XObjectFactory::deleteObject | ( | const XObject * | theXObject | ) | const`[protected]`

  | Delete a FactoryObject instance. Parameters:
  theXObject | the XObject instance to delete.

virtual bool XObjectFactory::doReturnObject | ( | XObject * | theXObject,
|  | bool | fInReset = false
| ) | `[protected, pure virtual]`

  | Return an XObject to the factory. Parameters:
  theXObject | XObject to be returned
  fInReset | true when called during reset().
Implemented in XObjectFactoryDefault.

MemoryManagerType& XObjectFactory::getMemoryManager | ( |  | ) |

| Reimplemented in XObjectFactoryDefault.

XObject::eObjectType XObjectFactory::getRealType | ( | const XObject & | theXObject | ) | const`[protected]`

  | Return the actual implementation type of an XObject. Parameters:
  theXObject | the XObject

virtual void XObjectFactory::reset | ( |  | ) | `[pure virtual]`

| Reset the instance. This invalidates all existing instances created with this XObjectFactory. Implemented in XObjectFactoryDefault.

bool XObjectFactory::returnObject | ( | XObject * | theXObject | ) |

  | Return an XObject to the factory. Parameters:
  theXObject | The XObject to be returned
Returns: true if the object belongs to the factory, false if not.
