WP_Theme_JSON_Resolver:: (13 methods):

Class: WP_Theme_JSON_Resolver  - X-Ref

Class that abstracts the processing of the different data sources
for site-level config and offers an API to work with them.

This class is for internal core usage and is not supposed to be used by extenders (plugins and/or themes).
This is a low-level API that may need to do breaking changes. Please,
use get_global_settings, get_global_styles, and get_global_stylesheet instead.

read_json_file( $file_path )   X-Ref

get_theme_data( $deprecated = array()   X-Ref

Data from theme.json will be backfilled from existing
theme supports, if any. Note that if the same data
is present in theme.json and in theme supports,
the theme.json takes precedence.

return: WP_Theme_JSON Entity that holds theme data.
since: 5.8.0

get_merged_data( $origin = 'custom' )   X-Ref
Returns the data merged from multiple origins.

There are three sources of data (origins) for a site:
default, theme, and custom. The custom's has higher priority
than the theme's, and the theme's higher than default's.

Unlike the getters
{@link https://developer.wordpress.org/reference/classes/wp_theme_json_resolver/get_core_data/ get_core_data},
{@link https://developer.wordpress.org/reference/classes/wp_theme_json_resolver/get_theme_data/ get_theme_data},
and {@link https://developer.wordpress.org/reference/classes/wp_theme_json_resolver/get_user_data/ get_user_data},
this method returns data after it has been merged with the previous origins.
This means that if the same piece of data is declared in different origins
(user, theme, and core), the last origin overrides the previous.

For example, if the user has set a background color
for the paragraph block, and the theme has done it as well,
the user preference wins.
