Interface FactType

All Superinterfaces:
  Externalizable, Serializable

    public interface FactType

extends Externalizable

FactType declarations are fact definitions (like classes) that are managed alongside the rules. You then communicate with the rulebase/knowledge base by using instances created by this. There are utility set and get methods on this, as well as in the FactFields. The Object that is used is a javabean (which was generated by the engine). You can also use reflection on it as normal.

Method Summary
`Object` | `get(Object bean, String field)` Gets the value of the specified field on the dynamic fact.
`Map<String,Object>` | `getAsMap(Object bean)` Get a map of the fields and their values for the bean.
`List<Annotation>` | `getClassAnnotations()` Returns the list of class-level annotations used in this class definition
`Class<?>` | `getFactClass()` Returns the Class
`FactField` | `getField(String name)` Returns the FactField identified by the given name.
`List<FactField>` | `getFields()` Returns the list of FactField in this FactType
`Map<String,Object>` | `getMetaData()` Returns the annotations of this class definition as key-value pairs.
`String` | `getName()` Returns the name of the FactType.
`String` | `getPackageName()` Returns the package this FactType is defined in.
`String` | `getSimpleName()` Returns the unqualified name of the FactType.
`String` | `getSuperClass()` Returns the name of the FactType's super type
`Object` | `newInstance()` Create a new fact based on the declared fact type.
`void` | `set(Object bean, String field, Object value)` Sets the value of the field on a fact.
`void` | `setFromMap(Object bean, Map<String,Object> values)` Sets the values of the bean from a map.

    `IllegalAccessException`

### set

    void set(Object bean,
             String field,

    `field` - the name of the field to set.
    `value` - the value to be set on the field.

### get

    Object get(Object bean,
               String field)

  Returns:
    the value of the field read from the fact

### getAsMap

    Map<String,Object> getAsMap(Object bean)

  Get a map of the fields and their values for the bean.

  Parameters:
    `bean` - the bean to read the fields from.
