omero::api::Exporter

Overview

[ "ami", "amd" ] interface Exporter extends StatefulServiceInterface

Stateful service for generating OME-XML or OME-TIFF from data stored in OMERO. Intended usage:


ExporterPrx e = sf.createExporter();

// Exporter is currently in the configuration state
// Objects can be added by id which should be present
// in the output.

e.addImage(1);


// As soon as a generate method is called, the objects
// added to the Exporter are converted to the specified
// format. The length of the file produced is returned.
// No more objects can be added to the Exporter, nor can
// another generate method be called.

long length = e.generateTiff();

// As soon as the server-side file is generated, read()
// can be called to get file segments. To create another
// file, create a second Exporter. Be sure to close all
// Exporter instances.

long read = 0
byte[] buf;
while (true) {
buf = e.read(read, 1000000);
// Store to file locally here
if (buf.length < 1000000) {
break;
}
read += buf.length;
}
e.close();

Operation Index

addImage: Adds a single image with basic metadata to the Exporter for inclusion on the next call to getBytes().
generateXml: Generates an OME-XML file.
generateTiff: Generates an OME-TIFF file.
read: Returns length bytes from the output file.

Operations

void addImage(long id) throws ServerError

Adds a single image with basic metadata to the Exporter for inclusion on the next call to getBytes().

long generateXml() throws ServerError

Generates an OME-XML file. The return value is the length of the file produced.

long generateTiff() throws ServerError

Generates an OME-TIFF file. The return value is the length of the file produced. This method ends configuration.

::Ice::ByteSeq read(long position, int length) throws ServerError

Returns length bytes from the output file. The file can be safely read until reset() is called.
