WP_HTML_Processor::is_html_integration_point() │ private │ WP 6.7.0

Indicates if the current token is an HTML integration point.

Note that this method must be an instance method with access to the current token, since it needs to examine the attributes of the currently-matched tag, if it's in the MathML namespace. Otherwise it would be required to scan the HTML and ensure that no other accounting is overlooked.

Method of the class: WP_HTML_Processor{}

No Hooks.

Return

true|false. Whether the current token is an HTML integration point.

Usage

// private - for code of main (parent) class only
$result = $this->is_html_integration_point(): bool;
