Introduction
The following Java sample programs are provided:
- ExtractFilter
- FilterFileByChunk
- FilterFileToFile
- FilterFileToStream
- FilterStreamByChunk
- FilterStreamToFile
- FilterStreamToStream
- FilterTest
The source code for the programs is in the directory javaapi/sample
. Included alongside the source code are compiled .class
files, and the following Batch (.bat
) and C Shell (.csh
) files that help run the corresponding program:
FilterFileToFile.bat (.csh)
FilterStreamToStream.bat (.csh)
FilterFileToStream.bat (.csh)
FilterStreamToFile.bat (.csh)
FilterFileByChunk.bat (.csh)
FilterStreamByChunk.bat (.csh)
Before the sample code can be compiled, you must replace the placeholder YOUR_KEYVIEW_LICENSE
in the Filter
constructor with your license information.
The compiled .class
files that are supplied in the SDK have an embedded trial license, which expires approximately five months after release. If you set the environment variable KV_SAMPLE_PROGRAM_LICENSE_FROM_FILEPATH
to a file path, the sample programs read your license from the specified file. This allows you to use the programs after the embedded trial license has expired, and to test or troubleshoot with your own license.
NOTE: The sample programs that demonstrate the use of an input stream show filtering from a java.io.InputStream
object. In KeyView version 12.9 and later, the stream methods are overloaded to allow you to pass a com.verity.api.SeekableInputStream
implementation into KeyView. OpenText recommends this option, as it allows KeyView to seek about in the file, only reading the parts it needs to read.
If you do need to use a Java InputStream, and you know the stream length, using the method overload that passes in the size might allow KeyView to avoid caching the whole file.
