Constructors
| EnumObject() |
default constructor |
Properties
| ConnectionInfo |
conection object |
| Filter |
filter for this level |
| FixedProperties |
list of the properties for which the value is know e.g. Name is know if the fileter is in the form [@Name='fff'] or [@Name='fff' and ( xxxxx ) ] |
| Name |
name of the xpath level |
| Request |
the request for this level, it is received from one level down or from user if it is the last level |
| ResultTypes |
return what types of results does this object support |
| Urn |
this property lives only while a request is serviced |
Methods
| AddProperty(ObjectProperty) |
add to the collection of properties |
| ComputeFixedProperties() |
calculate the list of fixed properties ( their value can be deduced from the filter ) |
| GetAliasPropertyName(String) |
get the property name as it will be aliased in the result set to the user |
| GetData(EnumResult) |
Gets the the EnumResult data acordingly to the Request wich was previoesly set by the Environment |
| GetFixedStringProperty(String, Boolean) |
get a fixed ( with known value from filter ) property of type string |
| GetProperties(ObjectPropertyUsages) |
returns the object properties by usage |
| GetProperty(String, ObjectPropertyUsages) |
accessor for a property by name and usage ( internal use ) |
| GetUrnProperties() |
until we have a formal way so that each object declares which properties it uses for urn try this best guess aproach |
| Initialize(Object, XPathExpressionBlock) |
initialize this level |
| PostProcess(EnumResult) |
This is called after the data has been retrived by the final object so the chian is preparing to be freed Because the objects are persisted between calls free any call specific data |
| RetrieveParentRequest() |
Override this method to generate a Request for the parent object The response from the parent object will give us the subset of parent objects for which the current level must generate it's result |
| TryGetProperty(String, ObjectPropertyUsages) |
accessor for a property by name and usage ( internal use ) |
