To do that, we have to add a file called .travis.yml containing build instructions.

For now, copy the one from eva, but without the jacoco:report coveralls:report, only mvn clean install

@amihaiemil I am not sure how to make unit tests for sequences.
As i guess i have to implement tests using RtYamlSequence class.
But nothing more in my mind )

These 2 interfaces should be abstract classes and provide an implementation for compareTo(), equals() and hashcode(), as these 3 methods should be the same and applicable for any implementation of YamlMapping and YamlSequence.

So far we're almost done with the "dumping" process - building Yaml structures or turning POJOs into YAML.

Now, we need to start thinking of the opposite process, 'loading', which will start with parsing an input - String, InputStrean, File or whatever else, into Yaml

Mockito can be used to unit test the caching decorators.
For instance the unit test for CachedYamlLine.trimmed() would look like this:

@Test
public void cachesTrimmedValue() {
    YamlLine mock = Mockito.mock(YamlLine.class);
    //instruct mock to return "this line" on first call to trimmed()
    //and throw exception on second call

    YamlLine cachedLine = new CachedYamlLine(mock);
    MatcherAssert.assertThat(cachedLine.trimmed(), Matchers.is("this line"));
    MatcherAssert.assertThat(cachedLine.trimmed(), Matchers.is("this line"));
}

If the caching doesn't work right and mock.trimmed() is called more than once, there will be an exception at the second assertion.

In this way we will unit test other caching decorators to come as well.

Some checkstyle issues were found by Travis. See here.

The puzzle 64-04f5df54 in src/main/java/com/amihaiemil/camel/YamlLine.java (lines 35-39) has to be resolved: This interface should extend Comparable, since we want YamlLines to be ordered after they are read from file.

Builder pattern should be used to construct YamlNode instanses like RtYamlMapping and RtYamlSequence.
We want to be as close to the javax Json api as possible, thus a yaml construction should look like this.

YamlMapping yaml = Yaml.createMappingBuilder()

    "architects",
    Yaml.createSequenceBuilder()

This method should return true if there is a nested YamlNode after the line or false otherwise.
It should actually check if the line ends with one of the characters: : > | -

The logic is already implemented in WellIndentedLine.indentation() -- it just needs to be moved, as it will also be used in OrderedYamlLines.indent(...)

Issue #79 waits for this to be solved.

Currently reading is done only for one Yaml per source, but for instance in a yaml file, more objects can be found, separated by ---

e.g.

---
a: b
c: d
---
a: f
c: g

According to the specification, the first (of the 3) YAML stages is a Representation Graph.

We should start with that, implement Node, Sequence, Scalar and Mapping models which will be used in building a YAML object.

Add method

abstract T value(); in class AbstractNode

naturally, AbstractNode becomes AbstractNode<T>

Afterwards, a mapping and a sequence should extend AbstractNode<Map<AbstractNode, AbstractNode>> and AbstractNode<Collection<AbstractNode>> respectively.

Initially, I wanted mapping and sequence to extend AbstractNodeCollection, but then stuff would, uselessly, become more complicated. e.g. when iterating over a List of AbstractNode you would have to use casting to see which is a collection, which not.

Code snippet is never used:

final Scalar<String> nullScalar = new Scalar<String>(
