Constructors

Constructor and Description
PatternFileFilter() Creates a new PatternFileFilter with no patternStrings List, implying that calling this constructor must be followed by a call to the #setPatterns method.
PatternFileFilter(boolean processNullValues, String patternPrefix, List<String> patterns, StringConverter<File> converter, boolean acceptCandidateOnPatternMatch) Compound constructor creating an PatternFileFilter from the supplied parameters.
PatternFileFilter(List<String> patterns) Creates a new PatternFileFilter using the supplied patternStrings which are interpreted as file suffixes.
PatternFileFilter(List<String> patternStrings, boolean acceptCandidateOnPatternMatch) Creates a new PatternFileFilter using the supplied patternStrings which are interpreted as file suffixes.

Field Detail

FILE_SUFFIX_PATTERN_PREFIX

public static final String FILE_SUFFIX_PATTERN_PREFIX

Java RegExp pattern which should be prepended to any file suffix pattern. For example, a pattern identifying files ending in "txt", the pattern is FILE_SUFFIX_PATTERN_PREFIX + "txt".

FILE_PATH_CONVERTER

public static final StringConverter<File> FILE_PATH_CONVERTER

Converter returning the canonical and absolute path for a File.

Constructor Detail

PatternFileFilter

public PatternFileFilter(boolean processNullValues,
                 String patternPrefix,
                 List<String> patterns,
                 StringConverter<File> converter,
                 boolean acceptCandidateOnPatternMatch)

Compound constructor creating an PatternFileFilter from the supplied parameters.

Parameters:

processNullValues - if true, this PatternFileFilter process null candidate values.

patternPrefix - a prefix to be prepended to any patterns submitted to this PatternFileFilter

patterns - The non-null list of Patters which should be applied within this PatternFileFilter.

converter - The StringConverter which converts Files to Strings for Pattern matching.

acceptCandidateOnPatternMatch - if true, this PatternFileFilter will matchAtLeastOnce candidate objects that match at least one of the supplied patterns. if false, this PatternFileFilter will noFilterMatches candidates that match at least one of the supplied patterns.

PatternFileFilter

public PatternFileFilter(List<String> patternStrings,
                 boolean acceptCandidateOnPatternMatch)

Creates a new PatternFileFilter using the supplied patternStrings which are interpreted as file suffixes. (I.e. prepended with FILE_SUFFIX_PATTERN_PREFIX and compiled to Patterns). The FILE_PATH_CONVERTER is used to convert Files to strings. The supplied acceptCandidateOnPatternMatch parameter indicates if this PatternFileFilter accepts or rejects candidates that match any of the supplied patternStrings.

Parameters:

patternStrings - The list of patternStrings to be used as file path suffixes.

acceptCandidateOnPatternMatch - if true, this PatternFileFilter will matchAtLeastOnce candidate objects that match at least one of the supplied patterns. if false, this PatternFileFilter will noFilterMatches candidates that match at least one of the supplied patterns.

PatternFileFilter

public PatternFileFilter(List<String> patterns)

Creates a new PatternFileFilter using the supplied patternStrings which are interpreted as file suffixes. (I.e. prepended with FILE_SUFFIX_PATTERN_PREFIX and compiled to Patterns). The FILE_PATH_CONVERTER is used to convert Files to strings. The retrieved PatternFileFilter accepts candidates that match any of the supplied patternStrings.

Parameters:

patterns - The list of patternStrings to be used as file path suffixes.

PatternFileFilter

public PatternFileFilter()

Creates a new PatternFileFilter with no patternStrings List, implying that calling this constructor must be followed by a call to the #setPatterns method.

The default prefix is FILE_SUFFIX_PATTERN_PREFIX, the default StringConverter is FILE_PATH_CONVERTER and this PatternFileFilter does by default accept candidates that match any of the supplied PatternStrings (i.e. an include-mode filter)

Method Detail

createExcludeFilterList

public static List<Filter<File>> createExcludeFilterList(org.apache.maven.plugin.logging.Log log,
                                         String... patterns)

Creates a new List containing an exclude-mode PatternFileFilter using the supplied patternStrings which are interpreted as file suffixes. (I.e. prepended with FILE_SUFFIX_PATTERN_PREFIX and compiled to Patterns). The FILE_PATH_CONVERTER is used to convert Files to strings.

Parameters:

patterns - A List of suffix patterns to be used in creating a new ExclusionRegularExpressionFileFilter.

log - The active Maven Log.

Returns:

A List containing a PatternFileFilter using the supplied suffix patterns to match Files.

createIncludeFilterList

public static List<Filter<File>> createIncludeFilterList(org.apache.maven.plugin.logging.Log log,
                                         String... patterns)

Creates a new List containing an include-mode PatternFileFilter using the supplied patternStrings which are interpreted as file suffixes. (I.e. prepended with FILE_SUFFIX_PATTERN_PREFIX and compiled to Patterns). The FILE_PATH_CONVERTER is used to convert Files to strings.

Parameters:

patterns - A List of suffix patterns to be used in creating a new ExclusionRegularExpressionFileFilter.

log - The active Maven Log.

Returns:

A List containing a PatternFileFilter using the supplied suffix patterns to match Files.
