=Binding=
Information between databoard's datatype and Java classes are transferred using a ''[javadoc/org/simantics/databoard/binding/Binding.html Binding]''.
The type and hierarchy structure of binding is same as its repsective type and [javadoc/org/simantics/databoard/type/Datatype.html Datatype]. 
As datatype has tree-structure, so does a binding.

==Built-in Bindings=

==Class Binding==
To acquire a binding, the developer can use a utility that creates one using Java reflection functions. 
    Binding binding = Bindings.getBinding( Double.class );

The Binding implementation is based on reflection or constructed from byte-code at runtime. Reflection is used if ASM library is not available. 

An automatic mechanism can create binding out of Java class, provided that certain rules are followed.

''Record-like class:''
    class Foo {
        public String name;
        public Object value;
    }

''Immutable class:''
    class Foo {
        private String name;
        private Object value;
        
        public Foo(String name, Object value) {
            this.name = name;
            this.value = value;
        }
        
        public String getName() {
            return name;
        }
        
        public Object getValue() {
            return value;
        }
        
    }

''Bean-like classes:''
    class Foo {
        private String name;
        private Object value;
        
        public void setName(String name) {
            this.name = name;
        }
        
        public void setValue(Object value) {
            this.value = value;
        }
        
        public String getName() {
            return name;
        }
        
        public Object getValue() {
            return value;
        }
        
    }

===Annotations===
You can aid the Binding creation with annotations.

 such as @Recursive, @Optional, @Arguments.
