Class ExtractResourcesProcessor

java.lang.Object
net.sf.basedb.util.extensions.manager.processor.ExtractResourcesProcessor
All Implemented Interfaces:
ExtensionsFileProcessor

public class ExtractResourcesProcessor extends Object implements ExtensionsFileProcessor
A file processor implementation that extracts resources from JAR files. The main target directory must be specified when an instance is constructed. Each processed JAR file is extracted into a subdirectory with the same name as the JAR file. Existing files are always overwritten.

The filter (in the form of a regular expressions pattern) can be specified to limit which files are extracted from the JAR file. The filter is also used to re-write target file names if they need to be different from the file names in the JAR file.

Note! It is recommended that this processor is paired with a ValidAndNewOrModifiedFilter since it is usually no point in extracting resources from invalid extensions.
