/** |
|
20
|
|
|
* Object representing to description for a DocBlock. |
|
21
|
|
|
* |
|
22
|
|
|
* A Description object can consist of plain text but can also include tags. A Description Formatter can then combine |
|
23
|
|
|
* a body template with sprintf-style placeholders together with formatted tags in order to reconstitute a complete |
|
24
|
|
|
* description text using the format that you would prefer. |
|
25
|
|
|
* |
|
26
|
|
|
* Because parsing a Description text can be a verbose process this is handled by the {@see DescriptionFactory}. It is |
|
27
|
|
|
* thus recommended to use that to create a Description object, like this: |
|
28
|
|
|
* |
|
29
|
|
|
* $description = $descriptionFactory->create('This is a {@see Description}', $context); |
|
30
|
|
|
* |
|
31
|
|
|
* The description factory will interpret the given body and create a body template and list of tags from them, and pass |
|
32
|
|
|
* that onto the constructor if this class. |
|
33
|
|
|
* |
|
34
|
|
|
* > The $context variable is a class of type {@see \phpDocumentor\Reflection\Types\Context} and contains the namespace |
|
35
|
|
|
* > and the namespace aliases that apply to this DocBlock. These are used by the Factory to resolve and expand partial |
|
36
|
|
|
* > type names and FQSENs. |
|
37
|
|
|
* |
|
38
|
|
|
* If you do not want to use the DescriptionFactory you can pass a body template and tag listing like this: |
|
39
|
|
|
* |
|
40
|
|
|
* $description = new Description( |
|
41
|
|
|
* 'This is a %1$s', |
|
42
|
|
|
* [ new See(new Fqsen('\phpDocumentor\Reflection\DocBlock\Description')) ] |
|
43
|
|
|
* ); |
|
44
|
|
|
* |
|
45
|
|
|
* It is generally recommended to use the Factory as that will also apply escaping rules, while the Description object |
|
46
|
|
|
* is mainly responsible for rendering. |
|
47
|
|
|
* |
|
48
|
|
|
* @see DescriptionFactory to create a new Description. |
|
49
|
|
|
* @see Description\Formatter for the formatting of the body and tags. |
