com.tsgrp.opencontent.core.transformation.TransformationImpl

All Implemented Interfaces:

ITransformation

public class TransformationImpl
extends java.lang.Object
implements ITransformation

Method Summary

Modifier and Type	Method and Description
boolean	canAsyncTransform(java.lang.String ticket, java.lang.String sourceMimetype, java.lang.String targetMimetype) Returns true if an asynchronous transformer exists for the given mimetypes.
java.io.File	getAsyncTransformedContent(java.lang.String ticket, java.lang.String fileId) Verifies the ticket, and then gets the async transformed content with the given FileId.

transformAsync

public java.lang.String transformAsync(java.lang.String ticket,
                                       java.io.InputStream content,
                                       java.lang.String sourceMimetype,
                                       java.lang.String targetMimetype,
                                       TransformationOptions options)

Description copied from interface: ITransformation

Transform the content of the byte[] passed in with the sourceMimeType into the targetMimeType. This method performs an asynchronous transformation. If you need a synchronous transformation use the ITransformation#transform(String, byte[], String, String, TransformationOptions) method. For proper functionality an asynchronous transformer must be configured for use.

Specified by:

transformAsync in interface ITransformation

Returns:

URL that the content will be available at once the transformation has completed on the server. Callers of this method are responsible for pulling the content from this URL on their own, as nothing is done with the content.

transform

public void transform(java.lang.String ticket,
                      java.io.InputStream content,
                      java.io.OutputStream output,
                      java.lang.String sourceMimetype,
                      java.lang.String targetMimetype,
                      TransformationOptions options)

Description copied from interface: ITransformation

Transforms the given byte[] of content (with the given 'sourceMimeType') into the targetMimeType with the given arguments.

Specified by:

transform in interface ITransformation

Parameters:

ticket - A valid OC ticket.

content - A byte[] containing the content to transform.

sourceMimetype - The mimetype of the content that is being transformed.

targetMimetype - The mimetype that the transformed content should be.

options - The TransformationOptions to use for transforming the content.

getAsyncTransformedContent

public java.io.File getAsyncTransformedContent(java.lang.String ticket,
                                               java.lang.String fileId)

Description copied from interface: ITransformation

Verifies the ticket, and then gets the async transformed content with the given FileId. Only implemented in implementations which support async transformation.

Specified by:

getAsyncTransformedContent in interface ITransformation

Returns:

canAsyncTransform

public boolean canAsyncTransform(java.lang.String ticket,
                                 java.lang.String sourceMimetype,
                                 java.lang.String targetMimetype)

Description copied from interface: ITransformation

Returns true if an asynchronous transformer exists for the given mimetypes. False otherwise.
