net.sf.saxon.value.CalendarValue
net.sf.saxon.value.DateTimeValue
| DateTimeValue | | final public class DateTimeValue extends CalendarValue (Code) | | A value of type DateTime
|
| Method Summary | |
| public CalendarValue | add(DurationValue duration)
| | public CalendarValue | adjustTimezone(int timezone)
Return a new dateTime with the same normalized value, but
in a different timezone. | | public int | compareTo(Object other)
Compare the value to another dateTime value.
This method is not used for XPath comparisons because it does not have access to the implicitTimezone
from the dynamic context. | | public int | compareTo(CalendarValue other, XPathContext cc)
Compare the value to another dateTime value, following the XPath comparison semantics
Parameters:
other - The other dateTime value
Parameters:
cc - A ConversionContext used to supply the implicit timezone negative value if this one is the earler, 0 if they are chronologically equal,positive value if this one is the later. | | public AtomicValue | convertPrimitive(BuiltInAtomicType requiredType, boolean validate, XPathContext context)
| | public Object | convertToJava(Class target, XPathContext context)
| | public CalendarValue | copy()
| | public boolean | equals(Object other)
| | public static DateTimeValue | fromJulianInstant(BigDecimal instant)
| | public GregorianCalendar | getCalendar()
Get a Calendar object representing the value of this DateTime. | | public AtomicValue | getComponent(int component)
Get a component of the value. | | public static DateTimeValue | getCurrentDateTime(XPathContext context)
Get the dateTime value representing the nominal
date/time of this transformation run. | | public byte | getDay()
| | public byte | getHour()
| | public ItemType | getItemType(TypeHierarchy th)
| | public int | getMicrosecond()
| | public byte | getMinute()
| | public byte | getMonth()
| | public byte | getSecond()
| | public CharSequence | getStringValueCS()
Convert to string
ISO 8601 representation. | | public int | getYear()
| | public int | hashCode()
| | public DateTimeValue | normalize(XPathContext cc)
Normalize the date and time to be in timezone Z. | | public SecondsDurationValue | subtract(CalendarValue other, XPathContext context)
| | public DateTimeValue | toDateTime()
| | public BigDecimal | toJulianInstant()
Get the Julian instant: a decimal value whose integer part is the Julian day number
multiplied by the number of seconds per day,
and whose fractional part is the fraction of the second.
This method operates on the local time, ignoring the timezone. |
| DateTimeValue | | public DateTimeValue(Calendar calendar, boolean tzSpecified)(Code) | | Constructor: create a dateTime value given a Java calendar object
Parameters:
calendar - holds the date and time
Parameters:
tzSpecified - indicates whether the timezone is specified |
| DateTimeValue | | public DateTimeValue(int year, byte month, byte day, byte hour, byte minute, byte second, int microsecond, int tz)(Code) | | Constructor: construct a DateTimeValue from its components.
This constructor performs no validation.
|
| adjustTimezone | | public CalendarValue adjustTimezone(int timezone)(Code) | | Return a new dateTime with the same normalized value, but
in a different timezone. This is called only for a DateTimeValue that has an explicit timezone
Parameters:
timezone - the new timezone offset, in minutes the date/time in the new timezone. This will be a new DateTimeValue unless no changewas required to the original value |
| compareTo | | public int compareTo(Object other)(Code) | | Compare the value to another dateTime value.
This method is not used for XPath comparisons because it does not have access to the implicitTimezone
from the dynamic context. It is available for schema comparisons, although it does not currently
implement the XML Schema semantics for timezone comparison (which involve partial ordering)
Parameters:
other - The other dateTime value negative value if this one is the earler, 0 if they are chronologically equal,positive value if this one is the later. For this purpose, dateTime values with an unknowntimezone are considered to be values in the implicit timezone (the Comparable interface requiresa total ordering).
throws:
ClassCastException - if the other value is not a DateTimeValue (the parameteris declared as Object to satisfy the Comparable interface) |
| compareTo | | public int compareTo(CalendarValue other, XPathContext cc)(Code) | | Compare the value to another dateTime value, following the XPath comparison semantics
Parameters:
other - The other dateTime value
Parameters:
cc - A ConversionContext used to supply the implicit timezone negative value if this one is the earler, 0 if they are chronologically equal,positive value if this one is the later. For this purpose, dateTime values with an unknowntimezone are considered to be values in the implicit timezone (the Comparable interface requiresa total ordering).
throws:
ClassCastException - if the other value is not a DateTimeValue (the parameteris declared as Object to satisfy the Comparable interface) |
| convertPrimitive | | public AtomicValue convertPrimitive(BuiltInAtomicType requiredType, boolean validate, XPathContext context)(Code) | | Convert to target data type
Parameters:
requiredType - an integer identifying the required atomic type
Parameters:
context - an AtomicValue, a value of the required type; or an ErrorValue |
| fromJulianInstant | | public static DateTimeValue fromJulianInstant(BigDecimal instant)(Code) | | Get the DateTimeValue corresponding to a given Julian instant
|
| getCalendar | | public GregorianCalendar getCalendar()(Code) | | Get a Calendar object representing the value of this DateTime. This will respect the timezone
if there is one, or be in GMT otherwise.
|
| getComponent | | public AtomicValue getComponent(int component) throws XPathException(Code) | | Get a component of the value. Returns null if the timezone component is
requested and is not present.
|
| getCurrentDateTime | | public static DateTimeValue getCurrentDateTime(XPathContext context)(Code) | | Get the dateTime value representing the nominal
date/time of this transformation run. Two calls within the same
query or transformation will always return the same answer.
|
| getDay | | public byte getDay()(Code) | | Get the day component
|
| getHour | | public byte getHour()(Code) | | Get the hour component
|
| getItemType | | public ItemType getItemType(TypeHierarchy th)(Code) | | Determine the data type of the exprssion
Type.DATE_TIME,
Parameters:
th - |
| getMicrosecond | | public int getMicrosecond()(Code) | | Get the year component
|
| getMinute | | public byte getMinute()(Code) | | Get the minute component
|
| getMonth | | public byte getMonth()(Code) | | Get the month component
|
| getSecond | | public byte getSecond()(Code) | | Get the second component
|
| getStringValueCS | | public CharSequence getStringValueCS()(Code) | | Convert to string
ISO 8601 representation. The value returned is the localized representation,that is it uses the timezone contained within the value itself. |
| getYear | | public int getYear()(Code) | | Get the year component
|
| hashCode | | public int hashCode()(Code) | | |
| normalize | | public DateTimeValue normalize(XPathContext cc)(Code) | | Normalize the date and time to be in timezone Z.
Parameters:
cc - used to supply the implicit timezone, used when the value hasno explicit timezone in general, a new DateTimeValue in timezone Z, representing the same instant in time.Returns the original DateTimeValue if this is already in timezone Z. |
| toDateTime | | public DateTimeValue toDateTime()(Code) | | Convert the value to a DateTime, retaining all the components that are actually present, and
substituting conventional values for components that are missing
|
| toJulianInstant | | public BigDecimal toJulianInstant()(Code) | | Get the Julian instant: a decimal value whose integer part is the Julian day number
multiplied by the number of seconds per day,
and whose fractional part is the fraction of the second.
This method operates on the local time, ignoring the timezone. The caller should call normalize()
before calling this method to get a normalized time.
