Method Detail

readManifestIntoMap

public static Map<String,String> readManifestIntoMap(Manifest mf)

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.

mapToManifest

public static Manifest mapToManifest(Map<String,String> attributes)

mapToManifest

parseManifest

public static Manifest parseManifest(InputStream in)
                              throws 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:

IOException

obtainManifestFromAppDir

public static Manifest obtainManifestFromAppDir(IDirectory appDir,
                                                String manifestName)
                                         throws IOException

Obtain a manifest from an IDirectory.

Parameters:

appDir -

manifestName - the name of manifest

Returns:

Manifest, or null if none found.

Throws:

IOException

split

public static List<String> split(String value,
                                 String delimiter)

Splits a delimiter separated string, tolerating presence of non separator commas within double quoted segments. 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:

List the components of the split String in a list
