public class UnZIP
extends AbstractMultiDecompress

Unzips a ZIP archive and broadcasts the full file names of the extracted files. A regular expression can be used to control the files that are being extracted. Whether the directory structure in the ZIP archive gets restored is optional.

Input/output:
- accepts:
java.lang.String
java.io.File
- generates:
java.lang.String[]

Valid options are:

-D (property: debug)
    If set to true, scheme may output additional info to the console.
 

-name <java.lang.String> (property: name)
    The name of the actor.
    default: UnZIP
 

-annotation <adams.core.base.BaseText> (property: annotations)
    The annotations to attach to this actor.
    default:
 

-skip (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded
    as it is.
 

-out-dir <adams.core.io.PlaceholderFile> (property: outputDir)
    The output directory to use.
    default: .
 

-reg-exp <java.lang.String> (property: regExp)
    The regular expression that the file names must match in order to be extracted.
    default: .*
 

-invert (property: invertMatching)
    If set to true, the matching sense of the regular expression is inverted.
 

-create-dirs (property: createDirectories)
    If set to true, the directory structure stored in the ZIP archive will be
    restored.
 

-buffer <int> (property: bufferSize)
    The size of the buffer in bytes for the data stream.
    default: 1024
