- IF_T100_MESSAGE in a Local Exception Class

This example demonstrates how a local exception class is linked with a message

Source Code

Description

The functional method meth raises an exception from the local exception class cx_t100 that implements the interface IF_T100_MESSAGE. When the exception is raised, the constructor is given a message class, a message number, and values for the placeholders of the message.

The constructor of the local exception class cx_t100 fills the attribute T100KEY of the interface IF_T100_MESSAGE with the values passed. In this way, the exception class represents the passed message from the table T100 in which the placeholders "&" are replaced with the content of the attributes text1 to text4.

The method main catches the exception in the reference variable oref and indicates the following:

• The exception text can be obtained using the method GET_TEXT of the component interface IF_MESSAGE in the interface IF_T100_MESSAGE. The implementation of the method GET_TEXT is in the superclass CX_ROOT, which already includes the interface IF_MESSAGE.

• The reference variable can be used directly as an operand of the statement MESSAGE.
