org.alfresco.repo.content.transform.AbstractContentTransformer2This class maintains the performance measures for the transformers as well, making sure that there is an extra penalty for transformers that fail regularly.

getTransformationTime(String sourceMimetype, String targetMimetype) Provides an estimate, usually a worst case guess, of how long a transformation will take. |

protected void |
recordError(String sourceMimetype, String targetMimetype, long transformationTime) Records an error and updates the average time as if the transformation took a long time, so that it is less likely to be called again. |

transform(ContentReader reader, ContentWriter writer) | |
void |
transform(ContentReader reader, ContentWriter writer, Map<String,Object> options) Transforms the content provided by the reader and source mimetype to the writer and target mimetype. |

void |
transform(ContentReader reader, ContentWriter writer, TransformationOptions options) Transforms the content provided by the reader and source mimetype to the writer and target mimetype with the provided transformation options. |

The transformation viability can be determined by an up front call to ContentTransformer.isTransformable(String, String, TransformationOptions).
The source and target mimetypes must be available on the ContentAccessor.getMimetype() methods of both the reader and the writer.
Both reader and writer will be closed after the transformation completes.
The provided options can be null.
The source and target mimetypes must be available on the ContentAccessor.getMimetype() methods of both the reader and the writer.
Both reader and writer will be closed after the transformation completes.
This method is used to determine, up front, which of a set of equally reliant transformers will be used for a specific transformation.
Subclasses should call this after every transformation in order to keep the running average of the transformation times up to date.
This method is thread-safe. The time spent in this method is negligible so the impact will be minor.
ExecutorService to be used for timeout-aware extraction.
If no ExecutorService has been defined a default of Executors.newCachedThreadPool() is used during AbstractMappingMetadataExtracter.init().
