Class EditableDocument

java.lang.Object

com.groupdocs.editor.EditableDocument

All Implemented Interfaces:

IAuxDisposable, IDisposable

public final class EditableDocument
extends Object
implements IAuxDisposable

Intermediate document, that contains content before and after editing

Instance of EditableDocument class can be produced by the Editor.edit() method or created by the user himself using static factories. EditableDocument internally stores document in its own closed format, which is compatible (convertible) with all import and export formats, that GroupDocs.Editor supports. In order to make document editable in any WYSIWYG client-side editor (like CKEditor or TinyMCE), EditableDocument provides methods for generating HTML markup and producing resources, that can be accepted by the user.

Method Detail

dispose

public final void dispose()

Disposes this Editable document instance, disposing its content and making its methods and properties non-working

Specified by:

dispose in interface IDisposable

fromFile

public static EditableDocument fromFile(String htmlFilePath,
                                        String resourceFolderPath)

Static factory, that creates an instance of EditableDocument from a HTML file, that is specified by a path to the *.html file itself and a folder with linked resources

Parameters:

htmlFilePath - String, that contains a full path to the HTML file. Cannot be null, should be valid file path, and file itself should exists.

resourceFolderPath - Optional path to the folder with HTML resources. If NULL, invalid or such folder doesn't exist, Editor will try to find the this folder by itself, analyzing the HTML markup

Returns:

New non-null instance of EditableDocument

fromMarkup

public static EditableDocument fromMarkup(String newHtmlContent,
                                          List<IHtmlResource> resources)

Static factory, that creates an instance of EditableDocument from specified HTML markup and a set of corresponding linked resources

Parameters:

newHtmlContent - String, that contains raw HTML markup, that should be parsed. Cannot be NULL, empty or invalid.

resources - Collection of all resources (images, stylesheets, fonts), that are used in the HTML-document, specified in newHtmlContent parameter. May be absent (NULL or empty collection).

Returns:

New non-null instance of EditableDocument

fromMarkupAndResourceFolder

public static EditableDocument fromMarkupAndResourceFolder(String newHtmlContent,
                                                           String resourceFolderPath)

Static factory, that creates an instance of EditableDocument from a specified HTML markup and from resources, located in the folder, specified by the full path

Parameters:

newHtmlContent - String, that contains raw HTML markup, that should be parsed. Cannot be NULL, empty or invalid.

resourceFolderPath - Mandatory path to the folder with resources. All stylesheets, which are located in this folder, will be used. Cannot be NULL or empty string, and this folder should exists.

This static factory is useful when content of HTML document is presented as a string, but all resources are located in some folder, and often links to these resources in HTML markup are invalid and absent. When invoking this method, it scans specified folder and automatically applies all found stylesheets to the document. This method is very useful when obtaining content from different HTML editors, which usually cut off the document metadata and so on.

Returns:

New non-null instance of EditableDocument

getAllResources

public final List<IHtmlResource> getAllResources()

Returns a list of all existing resources: all stylesheets, images from HTML and all stylesheets, fonts

This property returns a concatenated result of 'Images', 'Fonts', and 'Css' properties

getAudio

public final List<Mp3Audio> getAudio()

Returns a list of audio resources

getBodyContent

public final String getBodyContent()

Returns a body of the HTML document (content between opening and closing BODY tags without these tags) as a string.

Returns:

String, which contains the body of the HTML document

WYSIWYG editors operate with the body of the document and cannot correctly process its meta information from the HEAD block. This method is designed for such cases. This overload doesn't allow to adjust URIs for external resource requests.

getBodyContent

public final String getBodyContent(String externalImagesTemplate)

Returns a body of the HTML document (content between opening and closing BODY tags without these tags) as a string, where links to the external resources contain specified prefix.

Parameters:

externalImagesTemplate - Through this parameter used can specify a prefix, which will be added to the links to all external images in IMG elements, which will be present in the resultant HTML string. If NULL or empty, prefixes will not be added.
