A Buffer Overflow Prediction Approach Based on Software Metrics and Machine Learning

Table 3

Metrics.

	Name	Description
1	CountInput	Number of calls. Calls by the same method are counted only once, and calls by fields are not counted.
2	CountLine	The number of lines of code.
3	CountLineCode	The number of lines containing the code.
4	CountLineCodeDecl	The number of lines of the name class, the method name line is also recorded in this number.
5	CountLineCodeExe	The number of lines of pure executing class code.
6	CountLineComment	Annotation class code line number.
7	CountOutput	The number of calls to other methods, multiple calls to the same method are counted as one call. Return statement counts a call.
8	CountPath	Code paths that can be executed are related to cyclomatic complexity.
9	CountPathLog	truncated to an integer value, of the metric CountPath.
10	CountSemicolon	The number of semicolons.
11	CountStmt	The number of statements, even if multiple sentences are written on one line, is counted multiple times.
12	CountStmtDecl	Defines the number of class statements, including the method declaration line.
13	CountStmtExe	The number of class statements executed.
14	Cyclomatic	Circle complexity (standard calculation method).
15	CyclomaticModified	Circle complexity (the second calculation method).
16	CyclomaticStrict	Circle complexity (the third calculation method).
17	Essential	Basic complexity (standard calculation method).
18	Knots	Measure overlapping jumps.
19	MaxEssentialKnots	The maximum node after the structured programming structure has been deleted.
20	MaxNesting	Maximum nesting level, relating to cyclomatic complexity.
21	MinEssentialKnots	The minimum node after the structured programming structure has been deleted.
22	RatioCommentToCode	Code comment rate.
