Attempts to convert a String to a LocalAddeEntry.ServerName.

Parameters:

Returns:

One of ServerName. If there was no "sensible" conversion, the method returns LocalAddeEntry.ServerName.INVALID.

Throws:

NullPointerException - if s is null.

entryTypeToStr

public static String entryTypeToStr(AddeEntry.EntryType type)

Converts a given AddeEntry.EntryType to its String representation. Note that the resulting String is lowercase.

Parameters:

Attempts to convert a String to an AddeEntry.EntrySource.

Parameters:

s - String representation of an EntrySource. Cannot be null.

Returns:

Uses AddeEntry.EntrySource.valueOf(String) to convert s to an EntrySource and returns. If no conversion was possible, returns AddeEntry.EntrySource.USER.

Throws:

NullPointerException - if s is null.

strToEntryValidity

public static AddeEntry.EntryValidity strToEntryValidity(String s)

Attempts to convert a String to an AddeEntry.EntryValidity.

Parameters:

s - String representation of an EntryValidity. Cannot be null.

Throws:

NullPointerException - if s is null.

strToAddeFormat

public static LocalAddeEntry.AddeFormat strToAddeFormat(String s)

Attempts to convert a String into a member of LocalAddeEntry.AddeFormat. This method does a little bit of magic with the incoming String:

1. spaces are replaced with underscores
2. dashes ("-") are removed

This was done because older "RESOLV.SRV" files permitted the "MCV" key to contain spaces or dashes, and that doesn't play so well with Java's enums.

Parameters:

s - String representation of an AddeFormat. Cannot be null.

Returns:

Uses LocalAddeEntry.AddeFormat.valueOf(String) to convert the modified String into an AddeFormat and returns. If no conversion was possible, returns LocalAddeEntry.AddeFormat.INVALID.

Throws:

NullPointerException - if s is null.

addeFormatToStr

public static String addeFormatToStr(LocalAddeEntry.AddeFormat format)

extractMctableEntries

protected static Set<RemoteAddeEntry> extractMctableEntries(String path,
 String username,
 String project)

mapDatasetsToName

private static List<RemoteAddeEntry> mapDatasetsToName(Map<String,String> datasetToHost,
 Map<String,String> hostToIp,
 String username,
 String project)

This method is slightly confusing, sorry! Think of it kind of like a "SQL JOIN"...

Basically create RemoteAddeEntries by using a hostname to determine which dataset belongs to which IP.

Parameters:

datasetToHost - Map of ADDE groups to host names.

hostToIp - Map of host names to IP addresses.

username - ADDE username.

project - ADDE project number (as a String).

Returns:

List of RemoteAddeEntry instances. Each hostname will have a value from datasetToHost and the accounting information is formed from username and project.

private static Map<String,String> mapIpToName(Map<String,Set<String>> map)

mapDatasetsToIp

private static Map<String,String> mapDatasetsToIp(Map<String,String> datasets,
 Map<String,String> hostMap)

                                          throws IOException

Reads a "RESOLV.SRV" file and converts the contents into a Set of LocalAddeEntries.

Parameters:

filename - Filename containing desired local ADDE entries. Cannot be null.

Returns:

Set of local ADDE entries contained within filename.

Throws:

Parameters:

filename - Filename that will contain the local ADDE entries within entries. Cannot be null.

entries - Set of entries to be written to filename. Cannot be null.

Throws:

IOException - if there was a problem writing to filename.

demungeFileMask

public static String demungeFileMask(String path)

De-munges file mask strings.

This process is largely used to generate "Windows-friendly" masks.

Parameters:

path with Windows fixes applied.

Throws:

NullPointerException - if path is null.

mungeFileMask

public static String mungeFileMask(String mask)

Returns:

Path suitable for storing in RESOLV.SRV.

Throws:

NullPointerException - if mask is null.

Returns:

entries represented as strings.

See Also:

• asResolvEntry(LocalAddeEntry)

asResolvEntry

public static String asResolvEntry(LocalAddeEntry entry)

Converts a given LocalAddeEntry into a String that is suitable for including in a "RESOLV.SRV" file. This method does not append a newline to the end of the String.

Parameters:

entry - The LocalAddeEntry to convert. Should not be null.

Returns:

entry as a "RESOLV.SRV" entry.
