**Declaration**

```java
@Deprecated
public interface IPHXVersionedLibrarian
extends IPHXLibrarian

```

**Deprecated**: It is preferred to use `IPHXVersionedLibrarian3` as this class has methods that can leak resources.

This extends the [`IPHXLibrarian`](IPHXLibrarian.md) interface to include version information about components.

## Method Summary

Modifier and TypeMethod and Description`PHXComponentBranch``getComponentHistory(java.lang.String compClass, java.lang.String virtualDir)`  
**Deprecated.** Gets all version information about a particular component.### Methods inherited from interface [`IPHXLibrarian`](IPHXLibrarian.md):

`cleanUp`, `describe`, `getQueues`, `initialize`, `instantiate`, `instantiate`, `listComponents`, `listDirectories`

## Method Detail

### getComponentHistory

```java
PHXComponentBranch getComponentHistory(java.lang.String compClass,
                                       java.lang.String virtualDir)
                                throws java.lang.Exception

```

**Deprecated.** Gets all version information about a particular component. It is important that this class throws [`PHXNoSuchCategoryException`](PHXNoSuchCategoryException.md) and `ClassNotFoundException` in the appropriate cases as they are handled in special ways by the librarian mounter and librarian combiner.

**Parameters:**

- `compClass` - the class name for the component
- `virtualDir` - The directory the client asked for

**Returns:**

- An instance of [`PHXComponentBranch`](./../PHXComponentBranch.md) which contains all the versions and sub-branches available

**Throws:**

- [`PHXNoSuchCategoryException`](PHXNoSuchCategoryException.md) - If the virtualDirName passed in is invalid
- `java.lang.ClassNotFoundException` - If compClass doesn't indicate a valid class for the specified directory
- `java.lang.Exception` - If anything goes wrong
