Method Details

setIncludes

void setIncludes(String[] includes)

Sets the list of include patterns to use. All '/' and '\' characters are replaced by File.separatorChar, so the separator used need not match File.separatorChar.

When a pattern ends with a '/' or '\', "**" is appended.

Parameters:

includes - A list of include patterns. May be null, indicating that all files should be included. If a non-null list is given, all elements must be non-null.

setExcludes

void setExcludes(String[] excludes)

Sets the list of exclude patterns to use. All '/' and '\' characters are replaced by File.separatorChar, so the separator used need not match File.separatorChar.

When a pattern ends with a '/' or '\', "**" is appended.

Parameters:

excludes - A list of exclude patterns. May be null, indicating that no files should be excluded. If a non-null list is given, all elements must be non-null.

addDefaultExcludes

void addDefaultExcludes()

Adds default exclusions to the current exclusions set.

scan

void scan()

Scans the base directory for files which match at least one include pattern and don't match any exclude patterns.

Throws:

IllegalStateException - if the base directory was set incorrectly (i.e. if it is null, doesn't exist, or isn't a directory).

getIncludedFiles

String[] getIncludedFiles()

Returns the names of the files which matched at least one of the include patterns and none of the exclude patterns. The names are relative to the base directory.

Returns:

the names of the files which matched at least one of the include patterns and none of the exclude patterns.

getIncludedDirectories

String[] getIncludedDirectories()

Returns the names of the directories which matched at least one of the include patterns and none of the exclude patterns. The names are relative to the base directory.

Returns:

the names of the directories which matched at least one of the include patterns and none of the exclude patterns.

getBasedir

File getBasedir()

Returns the base directory to be scanned. This is the directory which is scanned recursively.

Returns:

the base directory to be scanned

setFilenameComparator

void setFilenameComparator(Comparator<String> filenameComparator)

Use a filename comparator in each directory when scanning.

Parameters:

filenameComparator - the Comparator instance to use
