Constructor Detail

GlobPathFilter

GlobPathFilter(java.lang.String glob)

Construct a new instance.

Parameters:

glob - the path glob to match

Method Detail

accept

public boolean accept(java.lang.String path)

Determine whether a path should be accepted.

Specified by:

accept in interface PathFilter

Parameters:

path - the path to check

Returns:

true if the path should be accepted, false if not

getGlobPattern

private static java.util.regex.Pattern getGlobPattern(java.lang.String glob)

Get a regular expression pattern which accept any path names which match the given glob. The glob patterns function similarly to ant file patterns. Valid metacharacters in the glob pattern include:

• "\" - escape the next character (treat it literally, even if it is itself a recognized metacharacter)
• "?" - match any non-slash character
• "*" - match zero or more non-slash characters
• "**" - match zero or more characters, including slashes
• "/" - match one or more slash characters. Consecutive / characters are collapsed down into one.

In addition, any glob pattern matches all subdirectories thereof. A glob pattern ending in / is equivalent to a glob pattern ending in /** in that the named directory is not itself included in the glob.

See also: "Patterns" in the Ant Manual

Parameters:

glob - the glob to match

Returns:

the pattern

hashCode

public int hashCode()

Description copied from interface: PathFilter

Calculate a unique hash code for this path filter. Equal path filters must yield identical hash codes.

Specified by:

hashCode in interface PathFilter

Overrides:

hashCode in class java.lang.Object

Returns:

the hash code

equals

public boolean equals(java.lang.Object obj)

Description copied from interface: PathFilter

Determine whether this filter is equal to another. Filters must implement meaningful (non-identity) equality semantics.

Specified by:

equals in interface PathFilter

Overrides:

equals in class java.lang.Object

Parameters:

obj - the other object

Returns:

true if this filter is the same

equals

public boolean equals(GlobPathFilter obj)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
