Methods Summary
public static int	getIntProperty(java.lang.String key, int def) Gets the implementation property indicated by the specified key or returns the specified default value as an int. param key the name of the implementation property. param def the default value for the property if not specified in the configuration files or command line over rides. return the int value of the implementation property, or def if there is no property with that key or the config value is not an int. exception NullPointerException if key is null. exception IllegalArgumentException if key is empty. /* * Get the maximum number of persistent connections * from the configuration file. */ String prop = getProperty(key); if (prop == null) { return def; } try { int temp = Integer.parseInt(prop); return temp; } catch (NumberFormatException nfe) { // keep the default } return def;
public static int	getNonNegativeIntProperty(java.lang.String key, int def) Gets the implementation property indicated by the specified key or returns the specified default value as an non-zero int. param key the name of the implementation property. param def the default value for the property if not specified in the configuration files or command line over rides. return the int value of the implementation property, or def if there is no property with that key or the config value is not an int. exception NullPointerException if key is null. exception IllegalArgumentException if key is empty. int temp = getIntProperty(key, def); if (temp >= 0) { return temp; } return def;
public static int	getPositiveIntProperty(java.lang.String key, int def) Gets the implementation property indicated by the specified key or returns the specified default value as an positive int. param key the name of the implementation property. param def the default value for the property if not specified in the configuration files or command line over rides. return the int value of the implementation property, or def if there is no property with that key or the config value is not a positive int (zero is not positive). exception NullPointerException if key is null. exception IllegalArgumentException if key is empty. int temp = getIntProperty(key, def); if (temp > 0) { return temp; } return def;
public static java.lang.String	getProperty(java.lang.String key) Gets the implementation property indicated by the specified key. param key the name of the implementation property. return the string value of the implementation property, or null if there is no property with that key. exception NullPointerException if key is null. exception IllegalArgumentException if key is empty. // If key is null, then a NullPointerException is thrown. // If key is blank, then throw a specific IllegalArgumentException if (key.length() == 0) { throw new IllegalArgumentException("key can't be empty"); } return getProperty0(key);
private static native java.lang.String	getProperty0(java.lang.String key) native interface to the configuration parameter storage. param key the name of the implementation property. return the string value of the implementation property, or null if there is no property with that key.
public static java.lang.String	getPropertyDefault(java.lang.String key, java.lang.String def) Gets the implementation property indicated by the specified key or returns the specified default value. param key the name of the implementation property. param def the default value for the property if not specified in the configuration files or command line over rides. return the string value of the implementation property, or def if there is no property with that key. exception NullPointerException if key is null. exception IllegalArgumentException if key is empty. String result = getProperty(key); return (result != null ? result : def);
