Field Detail

NO_VALUE

public static final String NO_VALUE

Used as a value in name2value to signify that the corresponding attribute has no value. This is much better than simply unsing null. The latter would not allow to rule out a multiple attribute without a value.

name2value

private final ListMap<String,String> name2value

Maps the name of an attribute to its value. The name must be a string. If there is a value (which is mandatory in xml) the value is also a string value. Otherwise it is NO_VALUE.

Constructor Detail

AttributesImpl

AttributesImpl(ListMap<String,String> name2value)

Creates a new empty AttributesImpl which represents the given attribute list.

Parameters:

name2value - a ListMap representing an attribute list, as specified for name2value.

Method Detail

noValueToNull

private static String noValueToNull(Object valueOrNot)

Converts NO_VALUE to null simply casting other arguments to type String.

Parameters:

valueOrNot - a String or the object NO_VALUE.

Returns:

a String which is

• null for valueOrNot == NO_VALUE.
• valueOrNot itself casted to a string otherwise.
