Parameters:

cfg - configuration Properties

key - the property key

Returns:

the Integer or null

Throws:

SearchException - both for empty (non-null) values and for Strings not containing a valid int representation.

parseInt

public static final int parseInt(String value,
           int defValue,
           String errorMsgOnParseFailure)

In case value is null or an empty string the defValue is returned

Parameters:

value -

defValue -

errorMsgOnParseFailure -

Returns:

the converted int.

Throws:

SearchException - if value can't be parsed.

parseInt

public static int parseInt(String value,
           String errorMsgOnParseFailure)

Parses a string into an integer value.

Parameters:

value - a string containing an int value to parse

errorMsgOnParseFailure - message being wrapped in a SearchException if value is null or not an integer

Returns:

the parsed integer value

Throws:

SearchException - both for null values and for Strings not containing a valid int.

getBooleanValue

public static final boolean getBooleanValue(Properties cfg,
                      String key,
                      boolean defaultValue)

Parameters:

cfg - configuration Properties

key - the property key

defaultValue - a boolean.

Returns:

the defaultValue if the property was not defined

Throws:

SearchException - for invalid format or values.

parseBoolean

public static final boolean parseBoolean(String value,
                   String errorMsgOnParseFailure)

Parses a string to recognize exactly either "true" or "false".

Parameters:

value - the string to be parsed

errorMsgOnParseFailure - the message to be put in the exception if thrown

Returns:

true if value is "true", false if value is "false"

Throws:

SearchException - for invalid format or values.
