Write Operator

Write Operator Description

Overview

Name:Write
Full name:org.esa.snap.core.gpf.common.WriteOp
Purpose:Writes a data product to a file.
Version:1.3

Description

This standard operator is used to store a data product to a specified file location.

It is used by the framework, e.g. the {@code gpt} command line tool, to write target products.

It may also be used by clients to write out break-point product files. This is done by placing a {@code WriteOp} node after any node in a processing graph:

 <node id="anyNodeId">
     <operator>Write</operator>
     <sources>
         <source>${anySourceNodeId}</source>
     </sources>
     <parameters>
         <file>/home/norman/eo-data/output/test.nc</file>
         <formatName>NetCDF</formatName>
         <deleteOutputOnFailure>true</deleteOutputOnFailure>
         <writeEntireTileRows>true</writeEntireTileRows>
         <clearCacheAfterRowWrite>true</clearCacheAfterRowWrite>
     </parameters>
 </node>
 

Clients may also use this operator in a programmatic way:

   WriteOp writeOp = new WriteOp(sourceProduct, file, formatName);
   writeOp.setDeleteOutputOnFailure(true);
   writeOp.setWriteEntireTileRows(true);
   writeOp.writeProduct(progressMonitor);
