public class FactoryCreateRule extends Rule
Rule implementation that uses an ObjectCreationFactory to create
a new object which it pushes onto the object stack. When the element is
complete, the object will be popped.
This rule is intended in situations where the element's attributes are needed before the object can be created. A common scenario is for the ObjectCreationFactory implementation to use the attributes as parameters in a call to either a factory method or to a non-empty constructor.

FactoryCreateRule(java.lang.Class<?> clazz)
Construct a factory create rule that will use the specified
class to create an
ObjectCreationFactory which will
then be used to create an object and push it on the stack. |
FactoryCreateRule(java.lang.Class<?> clazz,
boolean ignoreCreateExceptions)
Construct a factory create rule that will use the specified
class to create an
ObjectCreationFactory which will
then be used to create an object and push it on the stack. |
FactoryCreateRule(java.lang.Class<?> clazz,
java.lang.String attributeName)
Construct a factory create rule that will use the specified
class (possibly overridden by the specified attribute if present)
to create an
ObjectCreationFactory, which will then be used
to instantiate an object instance and push it onto the stack. |
FactoryCreateRule(java.lang.Class<?> clazz,
java.lang.String attributeName,
boolean ignoreCreateExceptions)
Construct a factory create rule that will use the specified
class (possibly overridden by the specified attribute if present)

class name to create an
ObjectCreationFactory which will
then be used to create an object and push it on the stack. |
FactoryCreateRule(java.lang.String className,
boolean ignoreCreateExceptions)
Construct a factory create rule that will use the specified
class name to create an
ObjectCreationFactory which will
then be used to create an object and push it on the stack. |
FactoryCreateRule(java.lang.String className,
java.lang.String attributeName)
Construct a factory create rule that will use the specified
class name (possibly overridden by the specified attribute if present)
to create an
ObjectCreationFactory, which will then be used
to instantiate an object instance and push it onto the stack. |
FactoryCreateRule(java.lang.String className,
java.lang.String attributeName,
boolean ignoreCreateExceptions)
Construct a factory create rule that will use the specified
class name (possibly overridden by the specified attribute if present)
to create an
ObjectCreationFactory, which will then be used
to instantiate an object instance and push it onto the stack. |
