Interface ModelSchemaContextItem

An item of the module:engine/model/schema~ModelSchemaContext schema context.

It contains 3 properties:

• name – the name of this item,
• * getAttributeKeys() – a generator of keys of item attributes,
• getAttribute( keyName ) – a method to get attribute values.

The context item interface is a highly simplified version of module:engine/model/node~ModelNode and its role is to expose only the information which schema checks are able to provide (which is the name of the node and node's attributes).

schema.on( 'checkChild', ( evt, args ) => {
	const ctx = args[ 0 ];
	const firstItem = ctx.getItem( 0 );

	console.log( firstItem.name ); // -> '$root'
	console.log( firstItem.getAttribute( 'foo' ) ); // -> 'bar'
	console.log( Array.from( firstItem.getAttributeKeys() ) ); // -> [ 'foo', 'faa' ]
} );
