Method Detail

getString

public static String getString(String name,
               Map values)

Get the config value as a String

Parameters:

name - The config setting name.

values - The map of config values

Returns:

The value, or null if not found

getString

public static String getString(String name,
               Map values,
               String defaultValue)

Get the config value as a String

Parameters:

name - The config setting name.

values - The map of config values

defaultValue - The default value to use if not found

Returns:

The value.

getBoolean

public static boolean getBoolean(String name,
                 Map values)

Get the config value as a boolean (default of false)

Parameters:

name - The config setting name.

values - The map of config values

Returns:

The value.

getBoolean

public static boolean getBoolean(String name,
                 Map values,
                 boolean defaultValue)

Get the config value as a boolean.

Parameters:

name - The config setting name.

values - The map of config values

defaultValue - The default value to use if not found

Returns:

The value.

getInt

public static int getInt(String name,
         Map values,
         int defaultValue)

Get the config value as an int

Parameters:

name - The config setting name.

values - The map of config values

defaultValue - The default value to use if not found

Returns:

The value.

getInteger

public static Integer getInteger(String name,
                 Map values)

Get the config value as an Integer

Parameters:

name - The config setting name.

values - The map of config values

Returns:

The value, or null if not found

clone

public static Map clone(Map<?,?> configurationValues)

Make a clone of the configuration values.

Parameters:

configurationValues - The config values to clone

Returns:

The clone

maskOut

public static Properties maskOut(Properties props,
                 String key)

replace a property by a starred version

Parameters:

props - properties to check

key - proeprty to mask

Returns:

cloned and masked properties

extractPropertyValue

public static String extractPropertyValue(String propertyName,
                          Properties properties)

Extract a property value by name from the given properties object.

Both null and empty string are viewed as the same, and return null.

Parameters:

propertyName - The name of the property for which to extract value

properties - The properties object

Returns:

The property value; may be null.

toMap

public static Map toMap(String propertyName,
        String delim,
        Properties properties)

Constructs a map from a property value.

The exact behavior here is largely dependant upon what is passed in as the delimiter.

Parameters:

propertyName - The name of the property for which to retrieve value

delim - The string defining tokens used as both entry and key/value delimiters.

properties - The properties object

Returns:

The resulting map; never null, though perhaps empty.

See Also:

extractPropertyValue(String, java.util.Properties)

toStringArray

public static String[] toStringArray(String propertyName,
                     String delim,
                     Properties properties)

Get a property value as a string array.

Parameters:

propertyName - The name of the property for which to retrieve value

delim - The delimiter used to separate individual array elements.

properties - The properties object

Returns:

The array; never null, though may be empty.

See Also:

extractPropertyValue(String, java.util.Properties), toStringArray(String, String)

toStringArray

public static String[] toStringArray(String stringForm,
                     String delim)

Convert a string to an array of strings. The assumption is that the individual array elements are delimited in the source stringForm param by the delim param.

Parameters:

stringForm - The string form of the string array.

delim - The delimiter used to separate individual array elements.

Returns:

The array; never null, though may be empty.

resolvePlaceHolders

public static void resolvePlaceHolders(Map<?,?> configurationValues)

Handles interpolation processing for all entries in a properties object.

Parameters:

configurationValues - The configuration map.

resolvePlaceHolder

public static String resolvePlaceHolder(String property)

Handles interpolation processing for a single property.

Parameters:

property - The property value to be processed for interpolation.

Returns:

The (possibly) interpolated property value.
