If “constructor” is not mentioned in “-chains-” property, it will be chained using the legacy mode: using “after” chaining, calling preamble() method before each constructor, if available, and calling postscript() after all constructors were executed. If the hint is “after”, it is chained as a regular method, but postscript() will be called after the chain of constructors. “constructor” cannot be chained “before”, but it allows a special hint string: “manual”, which means that constructors are not going to be chained in any way, and programmer will call them manually using this.inherited(). In the latter case postscript() will be called after the construction.

Example:

 
dojo.declare( "my.class", my.baseClass, {  
"-chains-": {  constructor: "'manual"  }
} );

This prevents the base class’s constructor from being called before the child’s.
