Configures a content query.
How to use
.
Description
You can use ContentChildren to get the QueryList
of elements or directives from the
content DOM. Any time a child element is added, removed, or moved, the query list will be
updated,
and the changes observable of the query list will emit a new value.
Content queries are set before the ngAfterContentInit
callback is called.
Metadata Properties:
- selector - the directive type or the name used for querying.
- descendants - include only direct children or all descendants.
- read - read a different token from the queried elements.
Let's look at an example:
npm package: @angular/core
exported from core/index defined in core/src/metadata/di.ts
