FileTextExtractable
class FileTextExtractable extends DataExtension (View source)
Decorate File or a File derivative to enable text extraction from the file content. Uses a set of subclasses of FileTextExtractor to do the extraction based on the content type of the file.
Adds an additional property which is the cached contents, which is populated on demand.

Methods
Called when this extension is added to a particular class
Temporarily modify the owner. The original owner is ensured to be restored
Clear the current owner, and restore extension to the state prior to the last setOwner()
Helper method to strip eval'ed arguments from a string that's passed to DataObject::$extensions or Object::add_extension().
Invoke extension point. This will prefer explicit extend prefixed
methods.
Edit the given query object to support queries for this extension
Update the database schema as required by this extension.
Influence the owner's can() permission check value to be disallowed (false), allowed (true) if no other processed results are to disallow, or open (null) to not affect the outcome.
Influence the owner's canEdit() permission check value to be disallowed (false), allowed (true) if no other processed results are to disallow, or open (null) to not affect the outcome.
Influence the owner's canDelete() permission check value to be disallowed (false), allowed (true) if no other processed results are to disallow, or open (null) to not affect the outcome.
Influence the owner's canCreate() permission check value to be disallowed (false), allowed (true) if no other processed results are to disallow, or open (null) to not affect the outcome.
Define extra database fields
This function is used to provide modifications to the form in the CMS by the extension. By default, no changes are made. DataObject->getCMSFields().
This function is used to provide modifications to the Validators used on a DataObject.
This function is used to provide modifications to the form used for front end forms. DataObject->getFrontEndFields()
This is used to provide modifications to the form actions used in the CMS. DataObject->getCMSActions().
this function is used to provide modifications to the summary fields in CMS by the extension By default, the summaryField() of its owner will merge more fields defined in the extension's $extra_fields['summary_fields']
this function is used to provide modifications to the fields labels in CMS by the extension By default, the fieldLabels() of its owner will merge more fields defined in the extension's $extra_fields['field_labels']
Tries to parse the file contents if a FileTextExtractor class exists to handle the file type, and returns the text. The value is also cached into the File record itself.
