DBCA Overview

Duplicate code analysis detects duplicate blocks for code files entered for code improvement and is currently checked with a total of two types.

• Type 1 (spaces, ignore comments): Ignores spaces and comments and detects duplicates.
• Type 2 (ignore spaces, comments, identifiers): Ignores spaces, comments, identifiers (variable names, etc.) and detects duplicates.

DBCA Execution

To create an analysis

1. Create an analysis accordint to Creating Analysis
2. In the Analysis Type window, select DBCA. Then, the Settings window will appear.

To setup the analysis

1. Set-up the analysis accoring to DBCA Settings, and click Apply button

To execute the analysis

• See Executing Analysis

To see the result

• See Viewing Analysis Result

Analysis Basics

• Analysis Name: Enter a name for the analysis.
• Target module: You can choose which modules exist in the project.
• Add Module button: You can add a new module to use.
• Direct selection: You can select a file directly without selecting a module.

Basic Option

• Duplication Type: For Type 1, it ignores spaces and comments to detect duplicates, and in Type 2, ignores spaces, comments, and identifiers to detect duplicates.
• Minimum Tokens: Enter the minimum number of tokens to check. If more tokens than this value are duplicated, it is determined as duplicate.
• Ignore duplicates in a file: If selected, duplicate code within the same file is not displayed in the analysis
• Include Header Files: If selected, it also displays duplicates within the header file

File Selection: Module

When Custom Files is not checked

• Left List: Files in the module that are not selected
• Right list: Selected files in module

File Selection: Custom Files

When Custom Files is checked

• Files to be examined

Criteria

It displays the duplicate code evaluation criteria of the Hyundai/Kia ES specification.

DBCA Result View

• ID: If the IDs are the same as duplicate code identification IDs, it means that they are duplicates.
• Location: If it's a bundle, you'll see duplicates, and if it's individual code, the file name displays the start and end lines.
• Included Tokens: The number of tokens that are duplicated. The number of tokens in the same ID is the same.
• Lines: Indicates the number of lines that contain the number of tokens. Even if the number of tokens is the same, the number of lines may vary.
• Verdict: Passed, conditionally passed, or disalted.
• Etc.: The user gets a commented description in the code. However, if you want to @HKSAT code, you should start with dbca and add a description.

DBCA Configuration

Default Values

• Default token size: Set the default value for the number of tokens displayed on the Default Options tab.

Partitions

• Partition max files: Duplicate token checks can cause out-of-memory errors if the target file is large or large. To avoid this, partitions are partitioned and inspected internally if necessary. Set the maximum number of files to fit in one partition.
• Partition size in MB: Set the maximum size of one partition.

Code View Highlight Colors

• Duplicated code block is the color for duplicated code blocks in the code view.
