Method Detail

getBoolean

public boolean getBoolean(String key,
                          boolean defaultValue)

Returns a single-valued property as a boolean if possible. If not set or not single-valued, returns the default value.

getInteger

public int getInteger(String key,
                      int defaultValue)

Returns a single-valued configuration property as an integer if possible. If not set, not single-valued, or not an integer, returns the default value.

getStrings

public List<String> getStrings(String key)

Returns all the values of a multi-valued configuration property, or an empty list if not found.

A single-valued and unset configuration property will be returned as a list containing one null.

getCommaSeparatedStrings

public List<String> getCommaSeparatedStrings(String key)

Reads a configuration property as a comma-separated list of strings. It may be a single-valued or multi-valued property. If multi-valued, each value will be split on commas and all items concatenated.

Leading and trailing space is automatically trimmed, and nulls and empty strings are automatically ignored.

Returns an empty list if the property doesn't exist.
