Modifier and Type	Method and Description
static Predicate<String>	excludes(String regexPatterns) Generate a predicate function that for any supplied string returns true if none of the regular expressions in the supplied comma-separated list matches the predicate parameter.
static <T> Predicate<T>	excludes(String regexPatterns, Function<T,String> conversion) Generate a predicate function that for any supplied parameter returns true if none of the regular expressions in the supplied comma-separated list matches the predicate parameter.
static Predicate<String>	includes(String regexPatterns) Generate a predicate function that for any supplied string returns true if any of the regular expressions in the supplied comma-separated list matches the predicate parameter.
static <T> Predicate<T>	includes(String regexPatterns, Function<T,String> conversion) Generate a predicate function that for any supplied parameter returns true if any of the regular expressions in the supplied comma-separated list matches the predicate parameter in a case-insensitive manner.

Method Detail

includes

public static Predicate<String> includes(String regexPatterns)

Generate a predicate function that for any supplied string returns true if any of the regular expressions in the supplied comma-separated list matches the predicate parameter.

Parameters:

regexPatterns - the comma-separated regular expression pattern (or literal) strings; may not be null

Returns:

the predicate function that performs the matching

excludes

public static Predicate<String> excludes(String regexPatterns)

Generate a predicate function that for any supplied string returns true if none of the regular expressions in the supplied comma-separated list matches the predicate parameter.

Parameters:

regexPatterns - the comma-separated regular expression pattern (or literal) strings; may not be null

Returns:

the predicate function that performs the matching

includes

public static <T> Predicate<T> includes(String regexPatterns,
                                        Function<T,String> conversion)

Generate a predicate function that for any supplied parameter returns true if any of the regular expressions in the supplied comma-separated list matches the predicate parameter in a case-insensitive manner.

Parameters:

regexPatterns - the comma-separated regular expression pattern (or literal) strings; may not be null

conversion - the function that converts each predicate-supplied value to a string that can be matched against the regular expressions; may not be null

Returns:

the predicate function that performs the matching

excludes

public static <T> Predicate<T> excludes(String regexPatterns,
                                        Function<T,String> conversion)

Generate a predicate function that for any supplied parameter returns true if none of the regular expressions in the supplied comma-separated list matches the predicate parameter.

Parameters:

regexPatterns - the comma-separated regular expression pattern (or literal) strings; may not be null

conversion - the function that converts each predicate-supplied value to a string that can be matched against the regular expressions; may not be null

Returns:

the predicate function that performs the matching

not

public static <R> Predicate<R> not(Predicate<R> predicate)

notNull

public static <T> Predicate<T> notNull()
