108

|
|

|
109
|
|
|
|
|
|
|
Need a simple transformer that mashes up a transform and a document into |
110
|
|
|
|
|
|
|
something awesome? This is your module then. |
111
|
|
|
|
|
|
|
|
112
|
|
|
|
|
|
|
This is the default for Document::Transformer to use. It expects data |
113
|
|
|
|
|
|
|
structures that align with whatever type constraints are passed into the |
114
|
|
|
|
|
|
|
constructor that represent a Document and a Transform. It implements the |
115
|
|
|
|
|
|
|
interface role L<Document::Transform::Role::Transformer> |

122

|
|
|
|
The default Transformer must have the constraints supplied to it via |
124
|
|
|
|
|
|
|
constructor. This constraint should check for whatever is a valid Document for |
125
|
|
|
|
|
|
|
the backend. |

|
transform takes a Document and an array of Transforms and performs the |
142
|
|
|
|
|
|
|
operations contained with the transforms against the document. Returns the |
143
|
|
|
|
|
|
|
transformed document. |
144
|
|
|
|
|
|
|
|
145
|
|
|
|
|
|
|
The type constraints for Document and Transform are stored in the attributes |
146
|
|
|
|
|
|
|
L</document_constraint> and L</transform_constraint>, respectively. |
