COND, SWITCH, result

...   operand
  $| ${ THROW $[RESUMABLE$|SHORTDUMP$] cx_class( $[message$]
                                            $[p1 = a1 p2 = a2 ...$] ) $} ...

Alternatives:

1. ... operand

2. ... THROW $[RESUMABLE$|SHORTDUMP$] cx_class( $[message$] $[p1 = a1 p2 = a2 ...$] )

Effect

These specifications after THEN and ELSE in the conditional expressions COND and SWITCH determine the result of the expression when the corresponding branch is selected.

Alternative 1

... operand

Effect

If an operand operand is specified, its value is converted to the data type type if necessary and returned as the result of the conditional expression. operand is a general expression position with the following restrictions:

• If operand is specified as a string expression, type must be character-like.

• If operand is specified as a bit expression, type must be byte-like.

Note

When an operand is specified, the conditional operators COND and SWITCH create a temporary data object whose data type is determined by the specified type and whose content is determined by the selected operand. This data object is used as the operand of a statement and then deleted. It is deleted either when the current statement is completed or when a relational expression is evaluated after the truth value is determined.

Example

Specification of the operands sum and sum + 1. The number of times a random number is less than half of its maximum value is counted.

Alternative 2

... THROW $[RESUMABLE$|SHORTDUMP$] cx_class( $[message$] $[p1 = a1 p2 = a2 ...$] )

Effect

The specification of THROW raises either an exception or a runtime error.

• If the addition SHORTDUMP is not specified, THROW works like the statement RAISE EXCEPTION TYPE and raises an exception of the exception class cx_class. The following applies here:

• The addition RESUMABLE can be used to make the exception resumable.

• A message can be passed to the exception object using the addition message.

• The input parameters p1, p2, ... of the instance constructor can be filled with actual parameters a1, a2.

• If the addition SHORTDUMP is specified, THROW works like the statement RAISE SHORTDUMP TYPE and raises a runtime error with the exception class cx_class, whereby a message can be also passed and the input parameters can be filled.

Notes

• If the exception class is specified after THROW, the parentheses must always be specified, even if no messages or actual parameters are passed. EXPORTING cannot be specified, nor is it necessary.

• Like the statement RAISE EXCEPTION, the specification THROW without the addition SHORTDUMP cannot be used in a method or function module in whose interface non-class-based exceptions are declared. Furthermore, it does not allow simultaneous use of the statement CATCH SYSTEM-EXCEPTIONS for the obsolete handling of catchable runtime errors, and the statements RAISE or MESSAGE RAISING to raise non-class-based exceptions in the current processing block.

Example

Raising of an exception of the class CX_DEMO_DYN_T100 that implements the interface IF_T100_DYN_MSG.

Example

Raising of a runtime error with an exception object of the class CX_DEMO_DYN_T100, which implements the interface IF_T100_DYN_MSG.
