Constructor Detail

EnumSet

public EnumSet(EnumSet.EnumItem[] items)

Constructor from array of enumeration items. The supplied items can be in any order, and the numeric values do not need to be contiguous (but must be unique, nonnegative, and should be fairly small). Note that this constructor will reorder the items in the supplied array as a side effect.

Parameters:

items - array of enumeration items (will be reordered)

EnumSet

public EnumSet(int start,
               String[] names)

Constructor from array of names. The value associated with each name is just the position index in the array added to the start value.

Parameters:

start - item value for first added name

names - array of names (no null entries allowed)

EnumSet

public EnumSet(EnumSet base,
               int start,
               String[] names)

Constructor from existing enumeration with added names. The value associated with each name is just the position index in the array added to the start value.

Parameters:

base - base enumeration to be extended

start - item value for first added name

names - array of names (no null entries allowed)

Method Detail

getName

public String getName(int value)

Get name for value if defined.

Parameters:

value - enumeration value

Returns:

name for value, or null if not defined

getNameChecked

public String getNameChecked(int value)

Get name for value. If the supplied value is not defined in the enumeration this throws an exception.

Parameters:

value - enumeration value

Returns:

name for value

getValue

public int getValue(String name)

Get value for name if defined.

Parameters:

name - possible enumeration name

Returns:

value for name, or -1 if not found in enumeration

getValueChecked

public int getValueChecked(String name)

Get value for name. If the supplied name is not present in the enumeration this throws an exception.

Parameters:

name - enumeration name

Returns:

value for name

checkValue

public void checkValue(int value)

Check value with exception. Throws an exception if the supplied value is not defined by this enumeration.

Parameters:

value - Value to check

maxIndex

public int maxIndex()

Get maximum index value in enumeration set.

Returns:

maximum
