The Adobe PDF Library Java API provides comprehensive PDF document creation and manipulation capabilities. Browse classes, enumerations, and interfaces organized by functional area.

## Instantiating the Library

The Library object must be instantiated on each thread before any of the PDFL objects are used. If the Library object is instantiated on any thread, it must also at least be instantiated on the main thread. In addition, for cleanup purposes, the Delete method **must** be called on the Library object before the thread is terminated.

```java
Library lib = new Library();
   // your application code that uses PDFL goes here...
lib.delete();
```

The Library object can be instantiated without specifying flags or a list of Resource locations. User resources will be placed first in the search list.

## Activating a License-Managed version

To use an activation key, the *setLicenseKey()* static method of the *Library* class can be set to a valid activation key **prior** to instantiating the library.

```java
Library.setLicenseKey("xxxx-xxxx-xxxx-xxxx");
Library lib = new Library();
```
