invoke

Invokes an expression. Arguments for invoke include an object that defines the input parameters and the row type. You must instantiate a JExpression object before you can use the invoke method. For the row type, use ERowType.INSERT, ERowType.DELETE, and ERowType.UPDATE.

Use the following syntax:

objectName.invoke(
    new Object[] { param1[, ... paramN ]}, 
    rowType
    );

The following table describes the arguments:

Argument	Datatype	Input/ Output	Description
objectName	JExpression	Input	JExpression object name.
parameters	-	Input	Object array that contains the input values for the expression.

For example, you create a function on the

Java Expressions

Functions

code entry tab named address_lookup() that returns an JExpression object that represents the expression. Use the following code to invoke the expression that uses input ports NAME and COMPANY:

JExpression myObject = address_lookup();
myObject.invoke(new Object[] { NAME,COMPANY }, ERowType INSERT);
