pact-jvm-consumer-java8_2.11 from group au.com.dius (version 3.5.24)
# pact-jvm-consumer-java8
Provides a Java8 lambda based DSL for use with Junit to build consumer tests.
# A Lambda DSL for Pact
This is an extension for the pact DSL provided by [pact-jvm-consumer](../pact-jvm-consumer). The difference between
the default pact DSL and this lambda DSL is, as the name suggests, the usage of lambdas. The use of lambdas makes the code much cleaner.
## Why a new DSL implementation?
The lambda DSL solves the following two main issues. Both are visible in the following code sample:
```java
new PactDslJsonArray()
.array() # open an array
.stringValue("a1") # choose the method that is valid for arrays
.stringValue("a2") # choose the method that is valid for arrays
.closeArray() # close the array
.array() # open an array
.numberValue(1) # choose the method that is valid for arrays
.numberValue(2) # choose the method that is valid for arrays
.closeArray() # close the array
.array() # open an array
.object() # now we work with an object
.stringValue("foo", "Foo") # choose the method that is valid for objects
.closeObject() # close the object and we're back in the array
.closeArray() # close the array
```
### The existing DSL is quite error-prone
Methods may only be called in certain states. For example `object()` may only be called when you're currently working on an array whereas `object(name)`
is only allowed to be called when working on an object. But both of the methods are available. You'll find out at runtime if you're using the correct method.
Finally, the need for opening and closing objects and arrays makes usage cumbersome.
The lambda DSL has no ambiguous methods and there's no need to close objects and arrays as all the work on such an object is wrapped in a lamda call.
### The existing DSL is hard to read
When formatting your source code with an IDE the code becomes hard to read as there's no indentation possible. Of course, you could do it by hand but we want auto formatting!
Auto formatting works great for the new DSL!
```java
array.object((o) -> {
o.stringValue("foo", "Foo"); # an attribute
o.stringValue("bar", "Bar"); # an attribute
o.object("tar", (tarObject) -> { # an attribute with a nested object
tarObject.stringValue("a", "A"); # attribute of the nested object
tarObject.stringValue("b", "B"); # attribute of the nested object
})
});
```
## Installation
### Maven
```
<dependency>
<groupId>au.com.dius</groupId>
<artifactId>pact-jvm-consumer-java8_2.12</artifactId>
<version>${pact.version}</version>
</dependency>
```
## Usage
Start with a static import of `LambdaDsl`. This class contains factory methods for the lambda dsl extension.
When you come accross the `body()` method of `PactDslWithProvider` builder start using the new extensions.
The call to `LambdaDsl` replaces the call to instance `new PactDslJsonArray()` and `new PactDslJsonBody()` of the pact library.
```java
io.pactfoundation.consumer.dsl.LambdaDsl.*
```
### Response body as json array
```java
import static io.pactfoundation.consumer.dsl.LambdaDsl.newJsonArray;
...
PactDslWithProvider builder = ...
builder.given("some state")
.uponReceiving("a request")
.path("/my-app/my-service")
.method("GET")
.willRespondWith()
.status(200)
.body(newJsonArray((a) -> {
a.stringValue("a1");
a.stringValue("a2");
}).build());
```
### Response body as json object
```java
import static io.pactfoundation.consumer.dsl.LambdaDsl.newJsonBody;
...
PactDslWithProvider builder = ...
builder.given("some state")
.uponReceiving("a request")
.path("/my-app/my-service")
.method("GET")
.willRespondWith()
.status(200)
.body(newJsonBody((o) -> {
o.stringValue("foo", "Foo");
o.stringValue("bar", "Bar");
}).build());
```
### Examples
#### Simple Json object
When creating simple json structures the difference between the two approaches isn't big.
##### JSON
```json
{
"bar": "Bar",
"foo": "Foo"
}
```
##### Pact DSL
```java
new PactDslJsonBody()
.stringValue("foo", "Foo")
.stringValue("bar", "Bar")
```
##### Lambda DSL
```java
newJsonBody((o) -> {
o.stringValue("foo", "Foo");
o.stringValue("bar", "Bar");
}).build()
```
#### An array of arrays
When we come to more complex constructs with arrays and nested objects the beauty of lambdas become visible!
##### JSON
```json
[
["a1", "a2"],
[1, 2],
[{"foo": "Foo"}]
]
```
##### Pact DSL
```java
new PactDslJsonArray()
.array()
.stringValue("a1")
.stringValue("a2")
.closeArray()
.array()
.numberValue(1)
.numberValue(2)
.closeArray()
.array()
.object()
.stringValue("foo", "Foo")
.closeObject()
.closeArray()
```
##### Lambda DSL
```java
newJsonArray((rootArray) -> {
rootArray.array((a) -> a.stringValue("a1").stringValue("a2"));
rootArray.array((a) -> a.numberValue(1).numberValue(2));
rootArray.array((a) -> a.object((o) -> o.stringValue("foo", "Foo"));
}).build()
```

mahout-parent from group org.apache.mahout (version 0.3)
Mahout's goal is to build scalable machine learning libraries. With scalable we mean: Scalable to reasonably large data sets. Our core algorithms for clustering, classfication and batch based collaborative filtering are implemented on top of Apache Hadoop using the map/reduce paradigm. However we do not restrict contributions to Hadoop based implementations: Contributions that run on a single node or on a non-Hadoop cluster are welcome as well. The core libraries are highly optimized to allow for good performance also for non-distributed algorithms. Scalable to support your business case. Mahout is distributed under a commercially friendly Apache Software license. Scalable community. The goal of Mahout is to build a vibrant, responsive, diverse community to facilitate discussions not only on the project itself but also on potential use cases. Come to the mailing lists to find out more. Currently Mahout supports mainly four use cases: Recommendation mining takes users' behavior and from that tries to find items users might like. Clustering takes e.g. text documents and groups them into groups of topically related documents. Classification learns from exisiting categorized documents what documents of a specific category look like and is able to assign unlabelled documents to the (hopefully) correct category. Frequent itemset mining takes a set of item groups (terms in a query session, shopping cart content) and identifies, which individual items usually appear together.
