Here is another neat new feature of ColdFusion 10 - Implicit CFC constructor. We can now set CFC properties when instantiating the CFC. This can be done by passing in name/value pairs or a structure. For example, let's assume we have the following CFC.
1<cfscript>
2component accessors="true" persistent="true" table="BOOKS" schema="APP" output="false"
3{
4 /* properties */
5
6 property name="bookID" column="BOOKID" type="numeric" ormtype="int" fieldtype="id";
7 property name="title" column="TITLE" type="string" ormtype="string";
8 property name="description" column="BOOKDESCRIPTION" type="string" ormtype="clob";
9}
10</cfscript>
2component accessors="true" persistent="true" table="BOOKS" schema="APP" output="false"
3{
4 /* properties */
5
6 property name="bookID" column="BOOKID" type="numeric" ormtype="int" fieldtype="id";
7 property name="title" column="TITLE" type="string" ormtype="string";
8 property name="description" column="BOOKDESCRIPTION" type="string" ormtype="clob";
9}
10</cfscript>
In the past we would need to do this:
1<cfscript>
2 book = new Book();
3 book.setTitle( "My Book Title" );
4 book.setDescription( "A really cool book" );
5</cfscript>
2 book = new Book();
3 book.setTitle( "My Book Title" );
4 book.setDescription( "A really cool book" );
5</cfscript>
But now, we can simply do this
1<cfscript>
2 book = new Book( title = "My Book Title", description = "A really cool book" );
3</cfscript>
2 book = new Book( title = "My Book Title", description = "A really cool book" );
3</cfscript>
Or, we can use this syntax.
1<cfscript>
2 book = new Book( {title:"My Book Title", description:"A really cool book"} );
3</cfscript>
2 book = new Book( {title:"My Book Title", description:"A really cool book"} );
3</cfscript>
Notice how when creating the structure, we are using ":" rather than "=". NOTE: You can still use "=" if you so desire, but by allowing us to use ":" it is more consistent with other languages, such as JavaScript.
