Breakpoint Properties

Breakpoints have a number of additional properties that change the point at which the breakpoint is hit, and that determine what happens at that point. These properties define:

•Any changes in action or behavior
•The line of code that the breakpoint moves to
•New constraints to restrict when the breakpoint is hit
•Information to be logged when the breakpoint is hit

Action

Identifies the change in behavior when the breakpoint is hit.

 

Marker Types

Line

Changes the line that this breakpoint is on.

 

 

Constraints

Associates a condition with the breakpoint.

The program is allowed to continue if the condition is not met when the breakpoint is encountered.

You can:

•Compose constraints using any variables that are in scope at the time the breakpoint occurs; for example:
•m_strName="John"
•m_strName=""
•m_nCount > 0

 

•Join constraints using logical operands, for example:
•(m_strName="John") AND (m_nCount > 0)

 

•Access elements of an array or pointer, for example:
•m_pNames[10]="John"

 

•Nest constraints, using parentheses; the debugger requires explicit precedence, for example:
•((x > 0) AND (y > 0)) OR ((x < 0) AND (y < 0)) OR ((x = 0) AND (y = 0))

 

 

Trace statement

Logs information to the Debug window when the breakpoint is hit.

To output a string variable, prefix the variable name with the '$' token; for primitive types use an '@' token.

 

Example of outputting a string member named m_Name of an object named X.

                The value of m_Name = $X.m_Name

 

Example of outputting an integer named m_Count of an object named X.

                The value of m_Count = @X.m_Count
