mjaron-datanode-java

[DRAFT] Abstract file tree with several implementations.

API description

This library defines universal INode interface and provides some implementations for this interface:

• FileNode - standard filesystem node based on java.io.File.

import pl.mjaron.datanode;

public class Sample {
    public static void main(String[] args) {
        final String sentence = "Hello world\nByeWorld.";
        final INode root = new FileNode("root_dir");
        root
                .getChild("subdirectory").mkdirs()
                .getChild("file.txt").remove().touch()
                .write(sentence);

        final String checkedContent = new FileNode("root_dir/subdirectory/file.txt").readString();
        Assertions.assertEquals(sentence, checkedContent);
    }
}

mjaron-datanode-java's Issues

Add method to delete all children but not this node.

Add method to get just children count.

FileNode.getChildren() throws NPE.

It shouldn't throw, just return empty list of children.

Add method assertExists() which throw runtime error when it doesn't or returns this.

Create INode method with get children passing given regex.

Proposed method signature:

interface INode {
    List<INode> getChildren(final String regex);
}
