This section provides a description of the Server side
expression editor.
By default, the server side expression editor includes a drop-down
list that has the following values:
- Constant
- String, Number and Boolean types are supported.
- Expression
- To define expressions with one or two operands. These operands
can be constants, expressions, functions or context values. An expression
supports arithmetic, comparison and boolean operands. Validation is
performed when building the expression and in case it is not correct,
a message is displayed.
- Context
- The context view includes a combo box with a context set. When
a context is selected from the combo, the corresponding data context
is shown in the view.
- Function
- The global functions support a set of basic global string, number
and date-manipulation functions. To initiate one function, the value
of all the function parameters must be specified. The value can be
set using the expression editor. The customization for project-specific
functions is supported. For more information, refer to the "Create
and register global function" section in the WebSphere® Multichannel Bank Transformation
Toolkit V7.1 Extension Development Guide.
