ClvListGrid - Extension of ListGrid

Simplification of CRUD usage:

ClvListGrid grid = new ClvListGrid(new ClvListGrid.Delegate() {
 
			@Override
			public void executeUpdate(ClvListGridResponse response) {
				// Map<String, Object> reqMap = response.getRequestMap();
				// response.response(...
			}
 
			@Override
			public void executeRemove(ClvListGridResponse response) {}
 
			@Override
			public void executeFetch(ClvListGridResponse response) {}
 
			@Override
			public void executeAdd(ClvListGridResponse response) {}
 
			@Override
			public DataSourceField[] createFields() {
				return new DataSourceField[] { new DataSourceTextField("Field Name") };
			}
		});

Note: If you are implementing executeRemove/Add/Fetch you must call response.response(...). Not in executeUpdate.

StringUtil

java.util.StringTokenizer is prohibited in the GWT client side. Here is my substitution:

 StringUtil.tokenizer("Jirka, Petr, Honza", ",", new ValueCallback() {
 
	@Override
	public void execute(String token) {
		// Your code
	}
 });

Way how to build string from collection:

 ToString<MaterialOption> toStr = new ToString<MaterialOption>() {
 
	@Override
	public String get(MaterialOption obj) { //make a token:
		return obj == null? null:obj.getOptionString();
	}
 };
 String result = StringUtil.toString(myCollection, ", ", toStr);

BCrypt

String hashed = BCrypt.hashpw("password", BCrypt.gensalt());
boolean verified = BCrypt.checkpw("password", hashed);
