com.sun.xacml.attr
Class TimeAttribute

java.lang.Object
  com.sun.xacml.attr.AttributeValue
      com.sun.xacml.attr.TimeAttribute

All Implemented Interfaces:: com.sun.xacml.cond.Evaluatable

public class TimeAttribute
extends AttributeValue

Representation of an xs:time value. This class supports parsing xs:time values. All objects of this class are immutable and thread-safe. The Date objects returned are not, but these objects are cloned before being returned.

Since:: 1.0

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

private java.lang.String encodedValue
          Cached encoded value (null if not cached yet).

static java.lang.String identifier
          Official name of this type

private static java.net.URI identifierURI
          URI version of name for this type

private int nanoseconds
          The number of nanoseconds beyond the time given by the timeGMT field.

private long timeGMT
          The time that this object represents in second resolution, in milliseconds GMT, with zero being midnight.

private int timeZone
          The time zone specified for this object (or TZ_UNSPECIFIED if unspecified).

static int TZ_UNSPECIFIED
          Time zone value that indicates that the time zone was not specified.

Fields inherited from class com.sun.xacml.attr.AttributeValue

          Returns a new TimeAttribute that represents the xs:time at a particular DOM node.

static TimeAttribute getInstance(java.lang.String value)
          Returns a new TimeAttribute that represents the xs:time value indicated by the string provided.

long getMilliseconds()
          Gets the number of milliseconds since midnight GMT that this attribute value represents.

int getNanoseconds()
          Gets the nanoseconds of this object.

int getTimeZone()
          Gets the time zone of this object (or TZ_UNSPECIFIED if unspecified).

java.util.Date getValue()
          Gets the time represented by this object.

int hashCode()
          Returns the hashcode value used to index and compare this object with others of the same type.

private void init(java.util.Date date, int nanoseconds, int timeZone, int defaultedTimeZone)
          Initialization code shared by constructors.

java.lang.String toString()
          Converts to a String representation.

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.

This object is used for synchronization whenever we need protection across this whole class.

earlyException

private static java.lang.RuntimeException earlyException

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

TZ_UNSPECIFIED

public static final int TZ_UNSPECIFIED

Time zone value that indicates that the time zone was not specified.

See Also:: Constant Field Values

timeGMT

private long timeGMT

The time that this object represents in second resolution, in milliseconds GMT, with zero being midnight. If no time zone was specified, the local time zone is used to convert to milliseconds relative to GMT.

nanoseconds

private int nanoseconds

The number of nanoseconds beyond the time given by the timeGMT field. The XML Query document says that fractional seconds must be supported down to at least 100 nanosecond resolution. The Date class only supports milliseconds, so we include here support for nanosecond resolution.

timeZone

private int timeZone

The time zone specified for this object (or TZ_UNSPECIFIED if unspecified). The offset to GMT, in minutes.

defaultedTimeZone

private int defaultedTimeZone

The time zone actually used for this object (if it was originally unspecified, the default time zone used). The offset to GMT, in minutes.

encodedValue

private java.lang.String encodedValue

Cached encoded value (null if not cached yet).

Constructor Detail

TimeAttribute

public TimeAttribute()

Creates a new TimeAttribute that represents the current time in the current time zone.

TimeAttribute

public TimeAttribute(java.util.Date date,
                     int nanoseconds,
                     int timeZone,
                     int defaultedTimeZone)

Creates a new TimeAttribute that represents the time supplied.

Method Detail

init

private void init(java.util.Date date,
                  int nanoseconds,
                  int timeZone,
                  int defaultedTimeZone)

Initialization code shared by constructors.

getInstance

public static TimeAttribute getInstance(org.w3c.dom.Node root)
                                 throws com.sun.xacml.ParsingException,
                                        java.lang.NumberFormatException,
                                        java.text.ParseException

Returns a new TimeAttribute that represents the xs:time at a particular DOM node.

getInstance

public static TimeAttribute getInstance(java.lang.String value)
                                 throws com.sun.xacml.ParsingException,
                                        java.lang.NumberFormatException,
                                        java.text.ParseException

Returns a new TimeAttribute that represents the xs:time value indicated by the string provided.

getValue

public java.util.Date getValue()

Gets the time represented by this object. The return value is a Date object representing the specified time down to second resolution with a date of January 1, 1970. Subsecond values are handled by the getNanoseconds 55 method.

getMilliseconds

public long getMilliseconds()

Gets the number of milliseconds since midnight GMT that this attribute value represents. This is the same time returned by getValue, and likewise the milliseconds are provided with second resolution.

getNanoseconds

public int getNanoseconds()

Gets the nanoseconds of this object.

getTimeZone

public int getTimeZone()

Gets the time zone of this object (or TZ_UNSPECIFIED if unspecified).

getDefaultedTimeZone

public int getDefaultedTimeZone()

Gets the time zone actually used for this object (if it was originally unspecified, the default time zone used).

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 returns a time value that could in turn be used by the factory to create a new instance with the same value.
