class SSViewer_FromString extends SSViewer (View source)

Properties
| static private string | $themes | A list (highest priority first) of themes to use Only used when {@link $theme_enabled} is set to TRUE. |
from SSViewer |
| static private string | $theme | The used "theme", which usually consists of templates, images and stylesheets. |
from SSViewer |
| static private bool | $theme_enabled | Use the theme. Set to FALSE in order to disable themes, which can be useful for scenarios where theme overrides are temporarily undesired, such as an administrative interface separate from the website theme. |
from SSViewer |
| static private string | $global_key | Default prepended cache key for partial caching |

| static private bool | $source_file_comments | from SSViewer | |
| static private bool | $rewrite_hash_links | Set if hash links should be rewritten |
from SSViewer |
| static private bool | $cache_template | The global template caching behaviour if no instance override is specified |
Methods
Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).
Gets the uninherited value for the given config option
An implementation of the factory method, allows you to create an instance of a class
Creates a class instance by the "singleton" design pattern.
Create a template from a string instead of a .ss file
Traverses the given the given class context looking for candidate template names which match each item in the class hierarchy. The resulting list of template candidates may or may not exist, but you can invoke {see SSViewer::chooseTemplate} on any list to determine the best candidate based on the current themes.
Set if hash links are rewritten for this instance
Get default value for rewrite hash links for all modules
Find the template to use for a given list
Returns true if at least one of the listed templates exists.
Call this to disable rewriting of links. This is useful in Ajax applications.
No description
Clears all parsed template files in the cache folder.
Set the cache object to use when storing / retrieving partial cache blocks.
Get the cache object to use when storing / retrieving partial cache blocks.
Flag whether to include the requirements in this response.
The process() method handles the "meat" of the template processing.
Execute the given template, passing it the given data.
Execute the evaluated string, passing it the given data.
Parse given template contents
Returns the filenames of the template that will be rendered. It is a map that may contain 'Content' & 'Layout', and will have to contain 'main'
Return an appropriate base tag for the given template.

Get inherited config value
mixed
uninherited(string $name)
Gets the uninherited value for the given config option
$this
set_stat(string $name, mixed $value)
deprecated
deprecated
Update the config value for a given property
static Injectable
create(array ...$args)
An implementation of the factory method, allows you to create an instance of a class
This method will defer class substitution to the Injector API, which can be customised via the Config API to declare substitution classes.
This can be called in one of two ways - either calling via the class directly, or calling on Object and passing the class name as the first parameter. The following are equivalent: $list = DataList::create('SiteTree'); $list = SiteTree::get();
static Injectable
singleton(string $class = null)
Creates a class instance by the "singleton" design pattern.
It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).
__construct(string $content, TemplateParser $parser = null)
static
flush()
Triggered early in the request when someone requests a flush.
static SSViewer
fromString(string $content, bool|void $cacheTemplate = null)
Create a template from a string instead of a .ss file
static
set_themes(array $themes = [])
Assign the list of active themes to apply.
If default themes should be included add $default as the last entry.
static
add_themes(array $themes = [])
Add to the list of active themes to apply
static array
get_themes()
Get the list of active themes
static
set_theme(string $theme)
deprecated
deprecated
static array
get_templates_by_class(string|object $classOrObject, string $suffix = '', string $baseClass = null)
Traverses the given the given class context looking for candidate template names which match each item in the class hierarchy. The resulting list of template candidates may or may not exist, but you can invoke {see SSViewer::chooseTemplate} on any list to determine the best candidate based on the current themes.
static ViewableData
topLevel()
Get the current item being processed
bool
getRewriteHashLinks()
Check if rewrite hash links are enabled on this instance
$this
setRewriteHashLinks(bool $rewrite)
Set if hash links are rewritten for this instance
static bool
getRewriteHashLinksDefault()
Get default value for rewrite hash links for all modules
static
setRewriteHashLinksDefault(bool $rewrite)
Set default rewrite hash links
setTemplate(string|array $templates)
static string
chooseTemplate(array|string $templates)
Find the template to use for a given list
setParser(TemplateParser $parser)
Set the template parser that will be used in template generation
TemplateParser
getParser()
Returns the parser that is set for template generation
static bool
hasTemplate(array|string $templates)
Returns true if at least one of the listed templates exists.
$this
dontRewriteHashlinks()
Call this to disable rewriting of links. This is useful in Ajax applications.
It returns the SSViewer objects, so that you can call new SSViewer("X")->dontRewriteHashlinks()->process();
string
exists()
static string
getTemplateFileByType(string $identifier, string $type = null)
static
flush_template_cache(bool $force = false)
Clears all parsed template files in the cache folder.
Can only be called once per request (there may be multiple SSViewer instances).
static
flush_cacheblock_cache(bool $force = false)
Clears all partial cache blocks.
Can only be called once per request (there may be multiple SSViewer instances).
setPartialCacheStore(CacheInterface $cache)
Set the cache object to use when storing / retrieving partial cache blocks.
CacheInterface
getPartialCacheStore()
Get the cache object to use when storing / retrieving partial cache blocks.
includeRequirements($incl = true)
Flag whether to include the requirements in this response.
DBHTMLText
process(ViewableData $item, array|null $arguments = null, $scope = null)
The process() method handles the "meat" of the template processing.
It takes care of caching the output (via {@link Cache}), as well as replacing the special "$Content" and "$Layout" placeholders with their respective subtemplates.
The method injects extra HTML in the header via {@link Requirements::includeInHTML()}.
Note: You can call this method indirectly by {@link ViewableData->renderWith()}.
static string
execute_template(string $template, mixed $data, array $arguments = null, object $scope = null, bool $globalRequirements = false)
Execute the given template, passing it the given data.
Used by the <% include %> template tag to process templates.
static string
execute_string(string $content, mixed $data, array $arguments = null, bool $globalRequirements = false)
Execute the evaluated string, passing it the given data.
Used by partial caching to evaluate custom cache keys expressed using template expressions
string
parseTemplateContent(string $content, string $template = "")
Parse given template contents
array
templates()
Returns the filenames of the template that will be rendered. It is a map that may contain 'Content' & 'Layout', and will have to contain 'main'
setTemplateFile(string $type, string $file)
static string
get_base_tag(string $contentGeneratedSoFar)
Return an appropriate base tag for the given template.
It will be closed on an XHTML document, and unclosed on an HTML document.
