Class ExclusionMatcher

java.lang.Object

io.github.sergeloie.languagecheck.scan.ExclusionMatcher

public final class ExclusionMatcher
extends Object

Decides whether a file or directory is excluded from a scan.

Three independent rules:

• excludedFiles - exact match on the normalized relative path.
• excludedDirs - directory-name match at any depth: a path is excluded when one of its path segments equals the entry, so build/ excludes both build/... and module/build/.... Also used by walkers to prune traversal.
• excludedExtensions - case-insensitive match on the file extension (dot stripped).

All paths are normalized to '/' separators; directory entries keep no trailing slash; extension entries are lower-cased. null entries in the input sets are ignored.

Method Summary

Modifier and Type	Method	Description
static String	extensionOf(String relPath)	Lower-cased file extension of a relative path, without the dot.
boolean	isExcludedDir(String relPath)	True if the directory at the normalized relative path relPath is named like an excluded directory (any path segment matches).
boolean	isExcludedFile(String relPath)	True if the file at the normalized relative path relPath must be skipped: exact file match, a directory-name match at any depth, or an excluded extension.
static ExclusionMatcher	none()	A matcher that excludes nothing.

Method Details

none

public static ExclusionMatcher none()

A matcher that excludes nothing.

isExcludedFile

public boolean isExcludedFile(String relPath)

True if the file at the normalized relative path relPath must be skipped: exact file match, a directory-name match at any depth, or an excluded extension.

isExcludedDir

public boolean isExcludedDir(String relPath)

True if the directory at the normalized relative path relPath is named like an excluded directory (any path segment matches). Used by walkers to prune whole subtrees.

extensionOf

public static String extensionOf(String relPath)

Lower-cased file extension of a relative path, without the dot. Returns "" for files without an extension and for dot-files such as .gitignore.
