Field Detail

LIB_DIRNAME

static final String LIB_DIRNAME

The name of the directory in which the properties file and (if applicable) native libraries are found.

PRODUCT_NAME

static final String PRODUCT_NAME

The common name for this class library. This is used for error messages, because most of the code for this class is duplicated between Cryptix and IJCE.

PROPERTIES_FILES

static final String[] PROPERTIES_FILES

The filename of the properties file.

Method Detail

getLibraryPath

static String getLibraryPath()

Returns the path of the library directory. The name of this directory is given by the LIB_DIRNAME constant.

The returned path is always absolute, and ends with a file separator character (e.g. "/" on Unix).

Throws: IOException if an error occurred during intialization, preventing the path from being determined.

getProperty

static String getProperty(String key)

Gets the value of a property.

getProperty

static String getProperty(String key, String defaultValue)

Gets the value of a property, or returns defaultValue if the property was not set.

list

static void list(PrintStream out)

Lists the properties to the PrintStream out.

list

static void list(PrintWriter out)

Lists the properties to the PrintWriter out.

propertyNames

static Enumeration propertyNames()

Returns an enumeration of all the property names.

save

static void save(OutputStream os, String comment)

Saves the properties to the OutputStream os, in the format used by java.util.Properties.save. The string comment is written as a comment in the first line of the output.
