Method Detail

all

public static PathFilter all(PathFilter... filters)

Get a path filter which returns true if all of the given filters return true.

Parameters:

filters - the filters

Returns:

the "all" filter

all

public static PathFilter all(Collection<PathFilter> filters)

Get a path filter which returns true if all of the given filters return true.

Parameters:

filters - the filters

Returns:

the "all" filter

any

public static PathFilter any(PathFilter... filters)

Get a path filter which returns true if any of the given filters return true.

Parameters:

filters - the filters

Returns:

the "any" filter

any

public static PathFilter any(Collection<PathFilter> filters)

Get a path filter which returns true if any of the given filters return true.

Parameters:

filters - the filters

Returns:

the "any" filter

none

public static PathFilter none(PathFilter... filters)

Get a path filter which returns true if none of the given filters return true.

Parameters:

filters - the filters

Returns:

the "none" filter

none

public static PathFilter none(Collection<PathFilter> filters)

Get a path filter which returns true if none of the given filters return true.

Parameters:

filters - the filters

Returns:

the "none" filter

not

public static PathFilter not(PathFilter filter)

Get a path filter which is true when the given filter is false, and vice-versa.

Parameters:

filter - the filter

Returns:

the inverting filter

match

public static PathFilter match(String glob)

Get a path filter which matches a glob. The given glob is a path separated by "/" characters, which may include the special "*" and "**" segment strings which match any directory and any number of nested directories, respectively.

Parameters:

glob - the glob

Returns:

a filter which returns true if the glob matches

is

public static PathFilter is(String path)

Get a path filter which matches an exact path name.

Parameters:

path - the path name

Returns:

a filter which returns true if the path name is an exact match

isChildOf

public static PathFilter isChildOf(String path)

Get a path filter which matches any path which is a child of the given path name (not including the path name itself).

Parameters:

path - the path name

Returns:

a filter which returns true if the path name is a child of the given path

isOrIsChildOf

public static PathFilter isOrIsChildOf(String path)

Get a path filter which matches any path which is equal to, or a child of, the given path name.

Parameters:

path - the path name

Returns:

a filter which returns true if the path name is equal to, or a child of, the given path

multiplePathFilterBuilder

public static MultiplePathFilterBuilder multiplePathFilterBuilder(boolean defaultValue)

Get a builder for a multiple-path filter. Such a filter contains multiple filters, each associated with a flag which indicates that matching paths should be included or excluded.

Parameters:

defaultValue - the value to return if none of the nested filters match

Returns:

the builder

acceptAll

public static PathFilter acceptAll()

Get a filter which always returns true.

Returns:

the accept-all filter
