继承	yii\base\Theme » yii\base\Component » yii\base\BaseObject
实现	yii\base\Configurable
可用版本自	2.0
源码	https://github.com/yiichina/yii2/blob/api/framework/base/Theme.php

Theme represents an application theme.

When yii\base\View renders a view file, it will check the active theme to see if there is a themed version of the view file exists. If so, the themed version will be rendered instead.

A theme is a directory consisting of view files which are meant to replace their non-themed counterparts.

Theme uses $pathMap to achieve the view file replacement:

It first looks for a key in $pathMap that is a substring of the given view file path;
If such a key exists, the corresponding value will be used to replace the corresponding part in the view file path;
It will then check if the updated view file exists or not. If so, that file will be used to replace the original view file.
If Step 2 or 3 fails, the original view file will be used.

For example, if $pathMap is ['@app/views' => '@app/themes/basic'], then the themed version for a view file @app/views/site/index.php will be @app/themes/basic/site/index.php.

It is possible to map a single path to multiple paths. For example,

'pathMap' => [
    '@app/views' => [
        '@app/themes/christmas',
        '@app/themes/basic',
    ],
]

In this case, the themed version could be either @app/themes/christmas/site/index.php or @app/themes/basic/site/index.php. The former has precedence over the latter if both files exist.

To use a theme, you should configure the theme property of the "view" application component like the following:

'view' => [
    'theme' => [
        'basePath' => '@app/themes/basic',
        'baseUrl' => '@web/themes/basic',
    ],
],

The above configuration specifies a theme located under the "themes/basic" directory of the Web folder that contains the entry script of the application. If your theme is designed to handle modules, you may configure the $pathMap property like described above.

$basePath 公共属性

这个主题的根路径。此主题的所有资源都位于此目录下。

public string getBasePath ( )
public void setBasePath ( $path )

$baseUrl 公共属性

The base URL (without ending slash) for this theme. All resources of this theme are considered to be under this base URL.

public string getBaseUrl ( )
public void setBaseUrl ( $url )

$pathMap 公共属性

The mapping between view directories and their corresponding themed versions. This property is used by applyTo() when a view is trying to apply the theme. Path aliases can be used when specifying directories. If this property is empty or not set, a mapping yii\base\Application::$basePath to $basePath will be used.

public array $pathMap = null
