Method Detail

evaluate

public boolean evaluate(de.unkrig.commons.lang.protocol.Mapping<String,Object> properties)

Description copied from interface: Find.Expression

Evaluates to true or false, depending on the properties:

String name

The name of the file, directory or archive entry. For archive entries, the name is relative to the archive, i.e. it may contain slashes ("/").

String path

The path of the file, directory or archive entry.

String type

The type of the file, directory or archive entry:

"directory"

A directory on the file system

"file"

A file on the file system

"archive-file"

An archive file on the file system

"archive-xxx-resource" (e.g. xxx="http")

A resource designated by a URL

"compressed-file"

A compressed file on the file system

"compressed-xxx-resource" (e.g. xxx="http")

A compressed resource

"directory-entry"

An archive entry which denotes a directory

"archive"

An archive nested inside an archive or compressed file

"compressed-contents"

Nested compressed contents

"normal-contents"

(Non-compressed, non-archive) contents in an archive or in a compressed file

The following properties apply to the current file or directory, or, iff the current document is the contents of a compressed file, or the contents of an archive entry, to the enclosing compressed resp. archive file:

String absolutePath

The absolute path of the file or directory; see File.getAbsolutePath().

String canonicalPath

The "canonical path" of the file or directory; see File.getCanonicalPath().

Date lastModifiedDate

The "modification time" of the file or directory. Notice that the comparison operators (e.g. "==") silently convert dates into strings with format "EEE MMM dd HH:mm:ss zzz yyyy" (see SimpleDateFormat).

long size

The size of the file (zero for directories).

long freeSpace

The number of unallocated bytes in the partition (see File.getFreeSpace().

long totalSpace

The size of the partition (see File.getTotalSpace().

long usableSpace

The number of bytes available to this virtual machine on the partition (see File.getUsableSpace().

boolean isDirectory

true for a directory, otherwise false.

boolean isFile

false for a directory, otherwise true.

boolean isHidden

Whether the file or directory is a hidden file (see File.isHidden()).

boolean isReadable

Whether the application can read the file or directory (see File.canRead().

boolean isWritable

Whether the application can modify the file or directory (see File.canWrite().

boolean isExecutable

Whether the application can execute the file (see File.canExecute()).

The following properties are available iff the current file is an archive file, or the current document exists within the contents of an archive:

String archiveFormat

The format of the immediately enclosing archive.

The following properties are available iff the current file is a compressed file, or the current document exists within compressed contents:

String compressionFormat

The format of the immediately enclosing compressed document.
