analyze()

boolean ppt4j.analysis.patch.PatchAnalyzer.analyze

(

)

throws IOException

Analyzes the patch for a specific CVE (Common Vulnerabilities and Exposures) entry. It processes the differences between the patched files and the original files, identifying pure additions, pure deletions, and modifications. It calculates a similarity score between the additions and deletions, and determines if the patch is present based on a threshold.

Returns

true if the patch is present, false otherwise

Exceptions

IOException

if an I/O error occurs during analysis

filterIfMatch()

PatchAnalyzer ppt4j.analysis.patch.PatchAnalyzer.filterIfMatch

(

String...

patterns

)

Adds the given patterns to the list of filters to be applied during matching analysis.

Parameters

patterns

the patterns to add to the filter list

Returns

the PatchAnalyzer object to allow method chaining

filterIfNotMatch()

PatchAnalyzer ppt4j.analysis.patch.PatchAnalyzer.filterIfNotMatch

(

String...

patterns

)

Adds the specified patterns to the list of patterns to filter if they do not match.

Parameters

patterns

the patterns to be added to the filterNotMatch list

Returns

the PatchAnalyzer object with the updated filterNotMatch list

main()

static void ppt4j.analysis.patch.PatchAnalyzer.main ( String[] args ) throws IOException

static

This method is the entry point of the PatchAnalyzer program. It takes in two command line arguments: dataset id and database type (PREPATCH or POSTPATCH). It then creates a new PatchAnalyzer object and calls the analyze method to perform analysis on the specified dataset with the given database type.
