EngineInterface

interface EngineInterface

EngineInterface is the interface each engine must implement.

All methods rely on a template name. A template name is a "logical" name for the template, and as such it does not refer to a path on the filesystem (in fact, the template can be stored anywhere, like in a database).

The methods should accept any name. If the name is not an instance of TemplateReferenceInterface, a TemplateNameParserInterface should be used to convert the name to a TemplateReferenceInterface instance.

Each template loader uses the logical template name to look for the template.

Methods

string
render(string|TemplateReferenceInterface $name, array $parameters = array())

Renders a template.

bool
exists(string|TemplateReferenceInterface $name)

Returns true if the template exists.

bool
supports(string|TemplateReferenceInterface $name)

Returns true if this class is able to render the given template.
