InvalidBitNumber class

The InvalidBitNumber exception class indicates that a bit number request by a bit manipulation function was incorrect, either negative, greater than the number of bits in the string, or non-integral. InvalidBitNumber was introduced in Model 204 version 7.5.

To produce a InvalidBitNumber exception for yourself, you typically use a User Language Throw statement with an InvalidBitNumber New constructor. For example, the following statement throws an InvalidBitNumber exception:

throw %(invalidBitNumber):new

The InvalidBitNumber methods

The following are the available InvalidBitNumber class methods.

Method	Description
BitNumber	Invalid bit number requested
New	Create a new InvalidBitNumber object

The methods in the class are described in the subsections that follow. In addition:

• "Notation conventions for methods" has information about the conventions followed.
• "InvalidBitNumber methods syntax" is a single page that contains the syntax diagrams of all the methods in the class.

BitNumber property

Invalid bit number requested (InvalidBitNumber class)

[Introduced in Model 204 7.5]

This property returns the invalid bit number that was requested and so caused the exception to be thrown.

Syntax

%number = invalidBitNumber:BitNumber

Syntax terms

%number	The invalid bit number that was requested and so caused the exception to be thrown
%invalidBitNumber	A reference to an instance of a InvalidBitNumber object.

New constructor

Create a new InvalidBitNumber object (InvalidBitNumber class)

[Introduced in Model 204 7.5]

This Constructor generates an instance of an InvalidBitNumber exception. The New method format is as follows:

Syntax

%invalidBitNumber = [%(InvalidBitNumber):]New( bitNumber= number)

Syntax terms

%invalidBitNumber	A reference to an instance of a InvalidBitNumber object.
[%(InvalidBitNumber):]	The class name in parentheses denotes a Constructor. See "Usage notes", below, for more information about invoking a InvalidBitNumber Constructor.
number	The bit number that will be returned by the BitNumber property.

Usage notes

• As described in "Using New or other Constructors", New can be invoked with no object, with an explicit class name, or with an object variable in the class, even if that object is Null:

  %invalidBitNumber = new %invalidBitNumber = %(InvalidBitNumber):new %invalidBitNumber = %invalidBitNumber:new
