New instance

Anatomy

<new class="var" var="var" var_params="var">
    ixml
</new>

Description: NEW creates a new object by instantiating a class and automatically calling all constructors along the lines of inheritance. Arguments may be passed to local variables as parameters on switch of context.

Attention:

NEW will throw an error for an undefined or invalid class.

The class variable 'class' may alternatively be an object in which case it's derived class is used instead.

The constructor incorporates a local context when being called. Therefore local variables may be declared within the constructors and methods.

The special local variable 'this' is a direct reference to the calling object of the constructor.

The special local variable 'arguments' is a reference to all arguments that have been passed to local variables on switch of context.

The RETURN, BREAK and NEXT operations may be used to break-off the execution of the constructor, thereby implicitly returning to the original control flow of the invoking control statement.

Examples

Example

<class var="Human">
  <property name="gender">male</property>
</class>

<class var="Person">
  <extends class="Human"/>
  
  <property name="firstname"/>
  <property name="lastname"/>
  
  <constructor>
    <set var="this.firstname">$firstname</set>
    <set var="this.lastname">$lastname</set>
  </constructor>
  
  <method name="getName">
    <set var="return">$this.firstname $this.lastname</set>
  </method>
</class>

<new class="Person" var="obj">
  <param name="firstname">Bill</param>
  <param name="lastname">Gates</param>
</new>

<call func="obj.getName" var="name"/>
<output>$name is $obj.gender!</output>

<!-- Bill Gates is male! -->
