Why Fantom ?
A practical programming languageHybrid OO and functional languageStatic typing with dynamic abilitiesElegant APIsModularity baked into the languageModern approach to concurrencyRESTFul designJSON style serialization
![Page 6: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/6.jpg)
Hello World
class HelloWorld { static Void main() {
echo(“Hello world !") }
}
![Page 7: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/7.jpg)
Pods
Pods are used to organize typesLike Java packages or C# namespacesQualified type names - <pod>::<type>
sys::DateTimeweb::Weblet
![Page 8: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/8.jpg)
Pod Declaration – pod.fan@podDepends = [Depend("sys 1.0"),
Depend("someOtherPod 1.0")] @podSrcDirs = [`fan/`, `test/`] pod myPod {
// symbols Str mySymbol := "value"
}
![Page 9: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/9.jpg)
Pods
Unit of deployment and versioningSimilar to a Java JAR file or a .NET assemblyPod names must be globally unique
Standard ZIP fileBundles Fantom code, meta-data, and file
resources
![Page 10: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/10.jpg)
Type System
Two kind of typesClassesMixins
Everything is an objectValue types – Bool, Int, Float
![Page 11: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/11.jpg)
Classes
Single class inheritanceMay inherit multiple MixinsThe root of all classes is the sys::Obj
class Foo : Bar { }
![Page 12: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/12.jpg)
Mixins
Similar Scala traitsJava/C# interfaces + method implementationNo statemixin Foo {
Int bar() { return 42 } }
![Page 13: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/13.jpg)
Enums
Enums are normal classesEnums have a fixed range of instances
enum Color { red, blue, green }
![Page 14: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/14.jpg)
Null Safety
Types may be nullable or non-nullableBy default types are non-nullableUse ? to specify a nullable type
Int? x := null
Int x := null // Error
![Page 15: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/15.jpg)
Generics
No user defined genericsLimited to List, Map, and Func
Str[] // list of Str [Str:User] // map of Users keyed by Str |Int a->Str| // takes Int, returns Str
![Page 16: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/16.jpg)
Why Fantom?
Built in modularity Everything is an Object
Value-types for performance
Statically typed mixinsNull safetyNo user defined generics
![Page 17: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/17.jpg)

Slots - Methods
Not virtual by defaultMust explicitly specify virtual and override
class Animal { virtual Void talk()
{ echo("generic") } }
class Cat : Animal {
override Void talk() { echo("meow") } }
![Page 19: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/19.jpg)
Slots – Methods Continued
Default parameters

Once methodsComputed first time, then cached
once Str fullName() {
return "$firstName $lastName" }

Slots - Fields
Use the := operator to provide an initial valueStr message := "hello world"
Implicitly use a getter/setterUse * to access field storage directly
*message := "hello world"
![Page 21: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/21.jpg)
Slots – Field Accessors
AccessorsInt x := 10 {
get { return *x } set { *x = val }
}
Can narrow field setter scopeInt x { private set } readonly Int x // the same
![Page 22: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/22.jpg)
Slots – Field Immutability
const - indicate that the field is immutableCannot be assigned outside of the
construction processValue of all const fields must be immutable
Any object instance of a const classThe result of Obj.toImmutable (1.0.47)
![Page 23: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/23.jpg)
Constructors
Multiple constructors allowedUse the new keywordConvention is makeXXX()Implicit make() constructor if not defined
new make(Str name := "anonymous"){this.name = name
} new makeFoo(Int x) { this.x = x }
![Page 24: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/24.jpg)
Calling Constructors
Called just like static factory methods
foo := Foo.make foo := Foo.make("bar") foo := Foo.makeFoo(5)
![Page 25: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/25.jpg)
Construction Calls
Special construction syntax: Type(args)Bind to Type.fromStr if exists and takes a
single Str argumentOtherwise bind to Type.make
foo := Foo.make // non-preferred foo := Foo() // preferred
![Page 26: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/26.jpg)

Closures
Last arg to a method, can be defined “outside”

foo(5, |->Int| { x }) // preferred foo(5) |->Int| { x }
![Page 36: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/36.jpg)
Closures
Used extensively in the API
[1, 2, 3].each |Int i| {echo(i)}[3, 8, 4].sort |Int a, Int b->Int| { a <=> b }
![Page 37: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/37.jpg)
It Blocks
Syntax sugar to bind this to another variable named it
foo := Foo() { age = 15 } foo := Foo(); foo.age = 15
Can set const fields
![Page 38: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/38.jpg)
Dynamic Invoke
Dynamic invoke operator: ->No compile time type checkingActually invokes Obj.trap()
By default trap() uses reflection to lookup and call methoda->x a.trap(“x”, [,])a->x = b a.trap(“x”, [b])a->x(b, c) a.trap(“x”, [b, c])

Concurrency
No mutable shared stateThreads may never share mutable state under
any circumstances
ImmutabilityMessage passingREST
UriSpaces - a whiteboard mechanism for multiple threads to share state
![Page 45: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/45.jpg)
Immutability
Immutable object = once constructed it never changes state
Any object instance of a const classThe result of Obj.toImmutable()
![Page 46: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/46.jpg)
Immutability - Const Classes
Use const keywordconst class Foo {}
Can only contain const fields or fields with no storage
Use const keyword - const Int id := 5Can only be set in the constructor
Must inherit from a const class or sys::Obj
![Page 47: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/47.jpg)
Message Passing - Actors
pool := ActorPool() a := Actor(pool) |Obj msg| {
echo("$Time.now: $msg") } a.send("start")a.sendLater(1sec, "1sec")
![Page 48: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/48.jpg)
Serialization
Syntax is a subset of the Fantom grammar
myPod::Person { name = "Homer Simpson" age = 39 children =
["Bart", "Lisa", "Maggie"] }
![Page 49: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/49.jpg)
Serialization
Tree basedNo attempt to keep track of object referencesTree nodesLiteralSimple - serialized via string representationComplex - aggregate of literal, simple, and/or complex
![Page 50: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/50.jpg)
Serialization - Simple
Types that are serializable to/from a stringtoStr() must return suitable string
representationMust have static fromStr() method
![Page 51: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/51.jpg)
Serialization - Simple@simple
class Point {
static Point fromStr(Str s) {
t := s.split(",");
return make(t[0].toInt, t[1].toInt)
}
override Str toStr() { return "$x,$y" }
Int x := 0
Int y := 0
}

Serialization - Complex
@serializable facetBy default will serialize all non-static fieldsUse @transient to skip fields@serializable
class Rectangle { Int x; Int y Int w; Int h @transient Int area}
![Page 53: Fantom on the JVM Devoxx09 BOF](https://reader033.vdocuments.site/reader033/viewer/2022061212/5495f5b5b479594c4d8b4e4a/html5/thumbnails/53.jpg)
Serialization - @collections
Nicer syntax for nesting children
Person { name = "Homer Simpson" Person { name = "Bart" } Person { name = "Lisa" } Person { name = "Maggie" }
}
