Method Details

commentFilter

public static Predicate<String> commentFilter(Iterable<String> commentPrefixes)

Creates predicate that filters out comment and blank lines. Leading spaces are removed and if the line then starts with a commentPrefix string it is considered a comment and will be removed

Parameters:

commentPrefixes - the list of comment prefixes.

Returns:

the Predicate that returns false for lines that start with commentPrefixes or are empty.

commentFilter

public static Predicate<String> commentFilter(String commentPrefix)

Creates predicate that filters out comment and blank lines. Leading spaces are removed and if the line then starts with a commentPrefix string it is considered a comment and will be removed

Parameters:

commentPrefix - the prefix string for comments.

Returns:

the Predicate that returns false for lines that start with commentPrefixes or are empty.

asFileFilter

public static FileFilter asFileFilter(DocumentName parent,
 DocumentNameMatcher nameMatcher)

Create a FileFilter from a PathMatcher.

Parameters:

parent - the document name for the parent of the file to be filtered.

nameMatcher - the path matcher to convert.

Returns:

a FileFilter.

asIterator

public static ExtendedIterator<String> asIterator(File patternFile,
 Predicate<String> commentFilters)

Creates an iterator of Strings from a file of patterns. Removes comment lines.

Parameters:

patternFile - the file to read.

commentFilters - A predicate returning true for non-comment lines.

Returns:

the iterable of Strings from the file.

asIterable

public static Iterable<String> asIterable(File patternFile,
 String commentPrefix)

Creates an iterable of Strings from a file of patterns. Removes comment lines.

Parameters:

patternFile - the file to read.

commentPrefix - the prefix string for comments.

Returns:

the iterable of Strings from the file.

asIterable

public static Iterable<String> asIterable(File patternFile,
 Predicate<String> commentFilters)

Creates an iterable of Strings from a file of patterns. Removes comment lines.

Parameters:

patternFile - the file to read.

commentFilters - A predicate returning true for non-comment lines.

Returns:

the iterable of Strings from the file.

isHidden

public static boolean isHidden(String fileName)

Returns true if the filename represents a hidden file

Parameters:

fileName - the file to check.

Returns:

true if it is the name of a hidden file.

qualifyPattern

public static String qualifyPattern(DocumentName documentName,
 String pattern)

Modifies the MatchPattern formatted pattern argument by expanding the pattern and by adjusting the pattern to include the basename from the documentName argument.

Parameters:

documentName - the name of the file being read.

pattern - the pattern to format.

Returns:

the completely formatted pattern

convertSeparator

public static String convertSeparator(String source,
 String from,
 String to)

Tokenizes the string based on the directory separator.

Parameters:

source - the source to tokenize.

from - the directory separator for the source.

to - the directory separator for the result.

Returns:

the source string with the separators converted.
