Method Detail

isFileBasedDatabaseType

public static boolean isFileBasedDatabaseType(java.lang.String type)

Returns true if type represents an in-process connection to a file backed database.

isInProcessDatabaseType

public static boolean isInProcessDatabaseType(java.lang.String type)

Returns true if type represents an in-process connection to database.

parseURL

public static HsqlProperties parseURL(java.lang.String url,
                                      boolean hasPrefix,
                                      boolean noPath)

Parses the url into components that are returned in a properties object.

The following components are isolated:

url: the original url

connection_type: a static string that indicate the protocol. If the url does not begin with a valid protocol, null is returned by this method instead of the properties object.

host: name of host in networked modes in lowercase

port: port number in networked mode, or 0 if not present

path: path of the resource on server in networked modes, minimum (slash) with path elements appended apart from servlet path which is (slash) plus the name of the servlet

database: database name. For memory, networked modes, this is returned in lowercase, for file: and res: databases the original case of characters is preserved. Returns empty string if name is not present in the url.

for each protocol if port number is not in the url

Additional connection properties specified as key/value pairs.

Parameters:

url - String

hasPrefix - indicates URL prefix is present

noPath - indicates empty path and verbatim use of path elements as database

Returns:

null returned if the part that should represent the port is not an integer or the part for database name is empty. Empty HsqlProperties returned if if url does not begin with valid protocol and could refer to another JDBC driver.
