Field Details

EMPTY

static final KeyPairResourceParser EMPTY

An empty parser that never fails, but always report that it cannot extract key pairs and returns empty list if asked to load

Method Details

canExtractKeyPairs

boolean canExtractKeyPairs(NamedResource resourceKey,
 List<String> lines)
                    throws IOException,
GeneralSecurityException

Parameters:

resourceKey - A hint as to the origin of the text lines

lines - The resource lines

Returns:

true if the parser can extract some key pairs from the lines

Throws:

IOException - If failed to process the lines

GeneralSecurityException - If failed to extract information regarding the possibility to extract the key pairs

extractDataBytes

static byte[] extractDataBytes(Collection<String> lines)

Converts the lines assumed to contain BASE-64 encoded data into the actual content bytes.

Parameters:

lines - The data lines - empty lines and spaces are automatically deleted before BASE-64 decoding takes place.

Returns:

The decoded data bytes

• joinDataLines(Collection)

joinDataLines

static String joinDataLines(Collection<String> lines)

containsMarkerLine

static boolean containsMarkerLine(List<String> lines,
 String marker)

containsMarkerLine

static boolean containsMarkerLine(List<String> lines,
 List<String> markers)

findMarkerLine

static AbstractMap.SimpleImmutableEntry<Integer,Integer> findMarkerLine(List<String> lines,
 List<String> markers)

Attempts to locate a line that contains one of the markers

Parameters:

lines - The list of lines to scan - ignored if null/empty

markers - The markers to match - ignored if null/empty

Returns:

A AbstractMap.SimpleImmutableEntry whose key is the first line index that matched and value the matched marker index - null if no match found

See Also:

• findMarkerLine(List, int, List)

findMarkerLine

static AbstractMap.SimpleImmutableEntry<Integer,Integer> findMarkerLine(List<String> lines,
 int startLine,
 List<String> markers)

Attempts to locate a line that contains one of the markers

Parameters:

lines - The list of lines to scan - ignored if null/empty

startLine - The scan start line index

markers - The markers to match - ignored if null/empty

Returns:

A AbstractMap.SimpleImmutableEntry whose key is the first line index that matched and value the matched marker index - null if no match found
