Constructor Detail

JarfileMetadataReader

public JarfileMetadataReader(File jarFile,
                             boolean scanNestedLibJars,
                             LogNode log)

Fast parser for jar manifest files. Doesn't intern strings or create Attribute objects like the Manifest class, so has lower overhead. Only extracts a few specific entries from the manifest file, if present. Assumes there is only one of each entry present in the manifest.
