Method Details

getMap
Description copied from interface:MapEventPropertyGetter
Returns a property of an event.- Specified by:
getMap
in interfaceMapEventPropertyGetter
- Parameters:
map
- to interrogate- Returns:
- property value
- Throws:
PropertyAccessException
- for property access errors
-
isMapExistsProperty
Description copied from interface:MapEventPropertyGetter
Exists-function for properties in a map-type event.- Specified by:
isMapExistsProperty
in interfaceMapEventPropertyGetter
- Parameters:
map
- to interrogate- Returns:
- indicator
-
get
Description copied from interface:EventPropertyGetterIndexed
Return the value for the property in the event object specified when the instance was obtained. Useful for fast access to event properties. Throws a PropertyAccessException if the getter instance doesn't match the EventType it was obtained from, and to indicate other property access problems.- Specified by:
get
in interfaceEventPropertyGetterIndexed
- Parameters:
eventBean
- is the event to get the value of a property fromindex
- the index value- Returns:
- value of indexed property in event
- Throws:
PropertyAccessException
- to indicate that property access failed
-
get
Description copied from interface:EventPropertyValueGetter
Return the value for the property in the event object specified when the instance was obtained. Useful for fast access to event properties. Throws a PropertyAccessException if the getter instance doesn't match the EventType it was obtained from, and to indicate other property access problems.- Specified by:
get
in interfaceEventPropertyValueGetter
- Parameters:
obj
- is the event to get the value of a property from- Returns:
- value of property in event
-
isExistsProperty
Description copied from interface:EventPropertyGetter
Returns true if the property exists, or false if the type does not have such a property.Useful for dynamic properties of the syntax "property?" and the dynamic nested/indexed/mapped versions. Dynamic nested properties follow the syntax "property?.nested" which is equivalent to "property?.nested?". If any of the properties in the path of a dynamic nested property return null, the dynamic nested property does not exists and the method returns false.
For non-dynamic properties, this method always returns true since a getter would not be available unless
- Specified by:
isExistsProperty
in interfaceEventPropertyGetter
- Parameters:
eventBean
- is the event to check if the dynamic property exists- Returns:
- indictor whether the property exists, always true for non-dynamic (default) properties
