alexheretic / dynamics Goto Github PK

Hi !

Is there any existing way to get boolean value without resorting to casting like this ?

Boolean b = (Boolean) dyna.dget("status.active").asObject();

Thank you !

Great library ! I wish i encountered this sooner to avoid all the headaches with splitting and loops.

I notice the current impl is to fetch and convert and dealing with possibly non existing path of map data.

Hence a feature request mutation capability for this library.
Two things quickly come to mind:

1. Adding a node by path
2. Removing a node by path

Anyway, thank you for providing this helpful library !

Hi,

It would be nice if the library would support HashSets. The following unit test illustrates my use case:

import alexh.weak.Dynamic;
import com.google.common.collect.ImmutableBiMap;
import com.google.common.collect.ImmutableList;
import org.junit.Test;

import java.util.HashSet;
import java.util.List;

import static java.util.Arrays.asList;
import static java.util.stream.Collectors.toList;
import static org.assertj.core.api.Assertions.assertThat;

public class DynamicsAddHashSetSupport {

    @Test
    public void returnsTwoProducts() {
        final ImmutableBiMap<String, Object> root = ImmutableBiMap.of(
            "products", ImmutableList.of(new HashSet<>(asList("Product 1", "Product 2"))));

        final List<String> products = Dynamic.from(root)
            .get("products")
            .children()
            .map(product -> product.convert().toString())
            .collect(toList());

        assertThat(products).contains("Product 1", "Product 2");
    }
}

If it isn't too much to ask - a module-info.java available would be nice. You can keep Java 8 compatibility by making a multi-release jar.

Hi,

It is a very nice job first of all, and cannot find any equivalent so far.

However, would it be possible to add the visitor pattern out of the box to the library please ?

I would be glad to provide a Pull Request for that.

Cheers.

Hello again from a long time fan !

Does dynamics currently support accessing values by array or list index ?

Map<String, Object> data = mapBuilder()
	.put("hello", "world")
	.put("list", Lists.newArrayList(mapBuilder()
			.put("nestedHello", "nestedWorld")
			.build()))
	.build();

Dynamic dyna = Dynamic.from(data);
assertEquals("world", dyna.get("hello").asString());

// both fails
assertEquals("nestedWorld", dyna.dget("list[0].nestedHello").asString());
assertEquals("nestedWorld", dyna.dget("list.0.nestedHello").asString());

Thank you !
