Method Details

getDefaults

protected static Properties getDefaults()

Sets default properties. This function is called only once before initializing internal data structure. Upon inserting a new property, this function MUST be extended.

Returns:

default (factory hard coded) initial properties

getProperties

public static Properties getProperties()

Returns inner properties data structure

Returns:

inner properties data structure

get

public static String get(String parameterName)

Returns default value of chosen parameter

Parameters:

parameterName - name of the parameter to be selected

Returns:

selected parameter default value in String format

getAsInteger

public static Integer getAsInteger(String parameterName)

Returns default value of chosen parameter in Integer form

Parameters:

parameterName - name of the parameter to be selected

Returns:

selected parameter default value in Integer format

Throws:

NumberFormatException - if the parameter does not contain a parsable integer

getAsLong

public static Long getAsLong(String parameterName)

Returns default value of chosen parameter in Long form

Parameters:

parameterName - name of the parameter to be selected

Returns:

selected parameter default value in Long format

Throws:

NumberFormatException - if the parameter does not contain a parsable long

getAsDouble

public static Double getAsDouble(String parameterName)

Returns default value of chosen parameter in Double form

Parameters:

parameterName - name of the parameter to be selected

Returns:

selected parameter default value in Double format

Throws:

NumberFormatException - if the parameter does not contain a parsable integer

getAsBoolean

public static Boolean getAsBoolean(String parameterName)

Returns default value of chosen parameter in Boolean form

Parameters:

parameterName - name of the parameter to be selected

Returns:

selected parameter default value in Boolean format

getAsNewInstance

public static Object getAsNewInstance(String parameterName)

Returns a new instance of default value of chosen parameter. Uses reflection to instantiate selected parameter's class.

Parameters:

parameterName - name of the parameter to be selected

Returns:

new instance of default value for selected parameter or null if value of this parameter is not a class to be instantiated

set

public static void set(String parameterName,
 String value)

Sets a default value for a chosen parameter

Parameters:

parameterName - name of the parameter to be chosen

value - new default value to be associated with given parameter

save

public static boolean save()

Saves current default values into FILENAME

Returns:

true iff file was correctly saved

reload

public static void reload()

Reloads current default values from FILENAME

revertToDefaults

public static void revertToDefaults()

Reverts current values to original default ones (hard coded)

getWorkingPath

public static File getWorkingPath()

Returns the working directory. Creates it if it does not exist.

Returns:

the working directory for JMT files
