Class DocumentPartSavingArgs

java.lang.Object

com.aspose.words.DocumentPartSavingArgs

public class DocumentPartSavingArgs
extends java.lang.Object

Provides data for the IDocumentPartSavingCallback.documentPartSaving(com.aspose.words.DocumentPartSavingArgs) callback.

To learn more, visit the Save a Document documentation article.

Remarks:

When Aspose.Words saves a document to HTML or related formats and HtmlSaveOptions.getDocumentSplitCriteria() / HtmlSaveOptions.setDocumentSplitCriteria(int) is specified, the document is split into parts and by default, each document part is saved into a separate file.

Class DocumentPartSavingArgs allows you to control how each document part will be saved. It allows to redefine how file names are generated or to completely circumvent saving of document parts into files by providing your own stream objects.

To save document parts into streams instead of files, use the P:Aspose.Words.Saving.DocumentPartSavingArgs.DocumentPartStream property.

Examples:

Shows how to split a document into parts and save them.

 
 public void documentPartsFileNames() throws Exception {
     Document doc = new Document(getMyDir() + "Rendering.docx");
     String outFileName = "SavingCallback.DocumentPartsFileNames.html";

     // Create an "HtmlFixedSaveOptions" object, which we can pass to the document's "Save" method
     // to modify how we convert the document to HTML.
     HtmlSaveOptions options = new HtmlSaveOptions();

     // If we save the document normally, there will be one output HTML
     // document with all the source document's contents.
     // Set the "DocumentSplitCriteria" property to "DocumentSplitCriteria.SectionBreak" to
     // save our document to multiple HTML files: one for each section.
     options.setDocumentSplitCriteria(DocumentSplitCriteria.SECTION_BREAK);

     // Assign a custom callback to the "DocumentPartSavingCallback" property to alter the document part saving logic.
     options.setDocumentPartSavingCallback(new SavedDocumentPartRename(outFileName, options.getDocumentSplitCriteria()));

     // If we convert a document that contains images into html, we will end up with one html file which links to several images.

Returns:

getDocumentPartFileName

public java.lang.String getDocumentPartFileName()

Gets the file name (without path) where the document part will be saved to.

Remarks:

This property allows you to redefine how the document part file names are generated during export to HTML or EPUB.

When the callback is invoked, this property contains the file name that was generated by Aspose.Words. You can change the value of this property to save the document part into a different file. Note that the file name for each part must be unique.

getDocumentPartFileName() / setDocumentPartFileName(java.lang.String) must contain only the file name without the path. Aspose.Words determines the path for saving using the document file name. If output document file name was not specified, for instance when saving to a stream, this file name is used only for referencing document parts. The same is true when saving to EPUB format.

Examples:

Shows how to split a document into parts and save them.

 
 public void documentPartsFileNames() throws Exception {
     Document doc = new Document(getMyDir() + "Rendering.docx");
     String outFileName = "SavingCallback.DocumentPartsFileNames.html";

P:Aspose.Words.Saving.DocumentPartSavingArgs.DocumentPartStream

Parameters:

value - The file name (without path) where the document part will be saved to.

Throws:

java.lang.Exception

getKeepDocumentPartStreamOpen

public boolean getKeepDocumentPartStreamOpen()

Specifies whether Aspose.Words should keep the stream open or close it after saving a document part.

Remarks:

Default is false and Aspose.Words will close the stream you provided in the P:Aspose.Words.Saving.DocumentPartSavingArgs.DocumentPartStream property after writing a document part into it. Specify true to keep the stream open. Please note that the main output stream provided in the call to M:Aspose.Words.Document.Save(System.IO.Stream,Aspose.Words.SaveFormat) or M:Aspose.Words.Document.Save(System.IO.Stream,Aspose.Words.Saving.SaveOptions) will never be closed by Aspose.Words even if getKeepDocumentPartStreamOpen() / setKeepDocumentPartStreamOpen(boolean) is set to false.

P:Aspose.Words.Saving.DocumentPartSavingArgs.DocumentPartStream

Returns:

The corresponding boolean value.

setKeepDocumentPartStreamOpen

public void setKeepDocumentPartStreamOpen(boolean value)

Specifies whether Aspose.Words should keep the stream open or close it after saving a document part.

Remarks:

Default is false and Aspose.Words will close the stream you provided in the P:Aspose.Words.Saving.DocumentPartSavingArgs.DocumentPartStream property after writing a document part into it. Specify true to keep the stream open. Please note that the main output stream provided in the call to M:Aspose.Words.Document.Save(System.IO.Stream,Aspose.Words.SaveFormat) or M:Aspose.Words.Document.Save(System.IO.Stream,Aspose.Words.Saving.SaveOptions) will never be closed by Aspose.Words even if getKeepDocumentPartStreamOpen() / setKeepDocumentPartStreamOpen(boolean) is set to false.
