APIs: Java Call-In Classes and Methods
Java applications call in to the operations of a Uniface component via the URB. Uniface generates Java classes and methods based on the component’s signature.
Class | Description |
---|---|
UnifaceComponent | Base class for Uniface components, from
which the generated wrapper classes are derived. Note: It can be used to implement your own classes for activating Uniface components, but it is much easier to use the generated wrapper classes. |
UnifaceEntity | Used to construct entity
parameters for Uniface operations. The class does the following:
|
UnifaceOccurrence | Used to construct occurrence parameters for Uniface operations. This class is a wrapper class around an entity data type, class UnifaceEntity, which holds one occurrence. The methods of the wrapper class guarantee that the embedded entity is always a valid occurrence (it contains one occurrence). |
UnifaceDateTime | Used to construct date and time parameters for Uniface operations. |
UnifaceException.class
NoSuchOperationException.class NoSuchInstanceException.class |
Exception classes that provide error handling for your Java applications. |
The Java Call-In API also provides a Configuration Manager and Configuration Manager Bean:
