More advanced example of a custom spray-json format
implicit object ProductItemFormat extends RootJsonFormat[ProductItem] {
// some fields are optional so we produce a list of options and
// then flatten it to only write the fields that were Some(..)
def write(item: ProductItem) = JsObject(
List(
Some("product_number" -> item.productNumber.toJson),
item.ean.map(ean β‡’ "ean" -> ean.toJson),
Some("title" -> item.title.toJson),
item.description.map(description β‡’ "description" -> description.toJson),
Some("price" -> item.price.toJson),

ArrayList | O(1) | O(n) | O(1) | O(n) | O(1) | Array
LinkedList | O(1) | O(1) | O(n) | O(n) | O(1) | Linked List

An example of how to customize the field mapping in spray-json to do generic transformation, in this case translating between camelcased Scala attributes and snakecase JSON attributes

NicMcPhee / Employees.xml
Created October 24, 2013 04:40
A simple example of reading and parsing an XML document in Java. This is based substantially on http://www.java-tips.org/java-se-tips/javax.xml.parsers/how-to-read-xml-file-in-java.html but cleaned up some so there's less duplicate logic. It assumes the existence of a file called "Employees.xml" which is also included here.
<?xml version="1.0"?>
<company>
<employee>
<firstname>Tom</firstname>
<lastname>Cruise</lastname>
</employee>
<employee>
<firstname>Paul</firstname>
<lastname>Enderson</lastname>
</employee>
