Zip Library

This module (incode-module-zip-dom) allows a zip to be created from a collection of files.

API & Implementation

The ZipService defines the following API:

public class ZipService {

    @lombok.Data                                                        (1)
    public static class FileAndName {
        private final String name;
        private final File file;

    public byte[] zip(final List<FileAndName> fileAndNameList) { ... }  (2)
    public byte[] zipFiles(final List<File> fileList) { ... }           (3)
1 immutable value type
2 Returns a byte array which is a zip of the collection of files. Rather than use the name of the file (which might be temporary files, for example), the name of each file to use (in its zip "entry") is provided.
3 Similar to zip(…​), but uses each file’s name as the zip entry (rather than providing it explicitly).

These actions are all programmatic and do not appear in the UI.

Maven can report modules dependencies using:

mvn dependency:list -o -pl modules/lib/zip/impl -D excludeTransitive=true

This shows no additional compile/runtime dependencies (other than Apache Isis itself).
