        Reads a manifest's main attributes into a String->String map.

        Will always return a map, empty if the manifest had no attributes.

        Parameters:
        mf - The manifest to read.
        Returns:
        Map of manifest main attributes.

        public static java.util.jar.Manifest mapToManifest​(java.util.Map<java.lang.String,​java.lang.String> attributes)
        mapToManifest

      • parseManifest

        public static java.util.jar.Manifest parseManifest​(java.io.InputStream in)
                                            throws java.io.IOException
        This method parses the manifest using a custom manifest parsing routine. This means that we can avoid the 76 byte line length in a manifest providing a better developer experience.
        Parameters:
        in - the input stream to read the manifest from.
        Returns:
        the parsed manifest
        Throws:

Eg. com.ibm.ws.eba.helloWorldService;version="[1.0.0, 1.0.0]" & com.ibm.ws.eba.helloWorldService;version="1.0.0" com.ibm.ws.eba.helloWorld;version="2";bundle-version="[2,30)" com.acme.foo;weirdAttr="one;two;three";weirdDir:="1;2;3"
        Parameters:
        value - the value to be split
        delimiter - the delimiter string such as ',' etc.
        Returns:
