Field Detail

identifier

public static final java.lang.String identifier

Official name of this type

See Also:

Constant Field Values

---

identifierURI

private static java.net.URI identifierURI

URI version of name for this type

This field is initialized by a static initializer so that we can catch any exceptions thrown by URI(String) and transform them into a RuntimeException, since this should never happen but should be reported properly if it ever does.

---

earlyException

private static java.lang.RuntimeException earlyException

RuntimeException that wraps an Exception thrown during the creation of identifierURI, null if none.

---

patternString

private static final java.lang.String patternString

Regular expression for yearMonthDuration (a la java.util.regex)

See Also:

Constant Field Values

---

GROUP_SIGN

private static final int GROUP_SIGN

The index of the capturing group for the negative sign.

See Also:

Constant Field Values

---

GROUP_YEARS

private static final int GROUP_YEARS

The index of the capturing group for the number of years.

See Also:

Constant Field Values

---

GROUP_MONTHS

private static final int GROUP_MONTHS

The index of the capturing group for the number of months.

See Also:

Constant Field Values

---

big12

private static java.math.BigInteger big12

Static BigInteger values. We only use these if one of the components is bigger than Integer.MAX_LONG and we want to detect overflow, so we don't initialize these until they're needed.

---

bigMaxLong

private static java.math.BigInteger bigMaxLong

---

pattern

private static java.util.regex.Pattern pattern

A shared Pattern object, only initialized if needed

---

negative

private boolean negative

Negative flag. true if duration is negative, false otherwise

---

years

private long years

Number of years

---

months

private long months

Number of months

---

totalMonths

private long totalMonths

Total number of months (used for equals)

---

encodedValue

private java.lang.String encodedValue

Cached encoded value (null if not cached yet).

Constructor Detail

YearMonthDurationAttribute

public YearMonthDurationAttribute(boolean negative,
                                  long years,
                                  long months)
                           throws java.lang.IllegalArgumentException

Creates a new YearMonthDurationAttribute that represents the duration supplied.

Method Detail

getInstance

public static YearMonthDurationAttribute getInstance(org.w3c.dom.Node root)
                                              throws com.sun.xacml.ParsingException

Returns a new YearMonthDurationAttribute that represents the xf:yearMonthDuration at a particular DOM node.

---

parseGroup

private static long parseGroup(java.util.regex.Matcher matcher,
                               int groupNumber)
                        throws java.lang.NumberFormatException

Returns the long value for the capturing group groupNumber. This method takes a Matcher that has been used to match a Pattern against a String, fetches the value for the specified capturing group, converts that value to an long, and returns the value. If that group did not match, 0 is returned. If the matched value is not a valid long, NumberFormatException is thrown.

---

getInstance

public static YearMonthDurationAttribute getInstance(java.lang.String value)
                                              throws com.sun.xacml.ParsingException

Returns a new YearMonthDurationAttribute that represents the xf:yearMonthDuration value indicated by the string provided.

---

isNegative

public boolean isNegative()

Returns true if the duration is negative.

---

getYears

public long getYears()

Gets the number of years.

---

getMonths

public long getMonths()

Gets the number of months.

---

equals

public boolean equals(java.lang.Object o)

Returns true if the input is an instance of this class and if its value equals the value contained in this class.

---

hashCode

public int hashCode()

Returns the hashcode value used to index and compare this object with others of the same type. Typically this is the hashcode of the backing data object.

---

toString

public java.lang.String toString()

Converts to a String representation.

---

encode

public java.lang.String encode()

Encodes the value in a form suitable for including in XML data like a request or an obligation. This must return a value that could in turn be used by the factory to create a new instance with the same value.

Specified by:

encode in class AttributeValue
