Factory method to construct a time value given the hour, minute, second, and nanosecond components. This constructor performs no validation.- Parameters:
hour- the hour value, 0-23minute- the minutes value, 0-59second- the seconds value, 0-59nanosecond- the number of nanoseconds, 0-999_999_999tz- the timezone displacement in minutes from UTC. Supply the valueCalendarValue.NO_TIMEZONEif there is no timezone component.

- either a TimeValue corresponding to the xs:time, or a ValidationFailure if the supplied value was invalid
-
getPrimitiveType
public BuiltInAtomicType getPrimitiveType()
Determine the primitive type of the value. This delivers the same answer as getItemType().getPrimitiveItemType(). The primitive types are the 19 primitive types of XML Schema, plus xs:integer, xs:dayTimeDuration and xs:yearMonthDuration, and xs:untypedAtomic. For external objects, the result is AnyAtomicType.- Specified by:
getPrimitiveTypein classAtomicValue- Returns:
- the primitive type
-
getHour
public byte getHour()
Get the hour component, 0-23- Returns:
- the hour
-
getMinute
public byte getMinute()
Get the minute component, 0-59- Returns:
- the minute
-
getSecond
public byte getSecond()
Get the second component, 0-59- Returns:
- the second
-
getMicrosecond
public int getMicrosecond()
Get the microsecond component, 0-999_999- Returns:
- the nanoseconds component divided by 1000, rounded towards zero
-
getNanosecond
public int getNanosecond()
Get the nanosecond component, 0-999_999- Returns:
- the nanoseconds
-
getPrimitiveStringValue
public java.lang.CharSequence getPrimitiveStringValue()
Convert to string- Specified by:
getPrimitiveStringValuein classAtomicValue- Returns:
- ISO 8601 representation, in the localized timezone (the timezone held within the value).
-
getCanonicalLexicalRepresentation
public java.lang.CharSequence getCanonicalLexicalRepresentation()
Get the canonical lexical representation as defined in XML Schema. This is not always the same as the result of casting to a string according to the XPath rules. For an xs:time it is the time adjusted to UTC- Specified by:
getCanonicalLexicalRepresentationin interfaceAtomicSequence- Overrides:
getCanonicalLexicalRepresentationin classAtomicValue- Returns:
- the canonical lexical representation if defined in XML Schema
-
toDateTime
public DateTimeValue toDateTime()
Convert to a DateTime value. The date components represent a reference date, as defined in the spec for comparing times.- Specified by:
toDateTimein classCalendarValue- Returns:
- the equivalent DateTimeValue
-
getCalendar
public java.util.GregorianCalendar getCalendar()
Get a Java Calendar object corresponding to this time, on a reference date- Specified by:
getCalendarin classCalendarValue- Returns:
- A Calendar object representing the date and time. Note that Java can only represent the time to millisecond precision.
-
copyAsSubType
public AtomicValue copyAsSubType(AtomicType typeLabel)
Make a copy of this time value, but with a different type label- Specified by:
copyAsSubTypein classAtomicValue- Parameters:
typeLabel- the new type label. This must be a subtype of xs:time.- Returns:
- the copied value
-
adjustTimezone
public TimeValue adjustTimezone(int timezone)
Return a new time with the same normalized value, but in a different timezone. This is called only for a TimeValue that has an explicit timezone- Specified by:
adjustTimezonein classCalendarValue- Parameters:
timezone- the new timezone offset, in minutes- Returns:
- the time in the new timezone. This will be a new TimeValue unless no change was required to the original value
-
getComponent
public AtomicValue getComponent(AccessorFn.Component component) throws XPathException
Get a component of the value. Returns null if the timezone component is requested and is not present.- Overrides:
getComponentin classAtomicValue- Parameters:
component- the required component- Returns:
- the value of the requested component of this value
- Throws:
XPathException- if a dynamic error occurs
-
compareTo
public int compareTo(java.lang.Object other)
Compare the value to another dateTime value- Specified by:
compareToin interfacejava.lang.Comparable- Parameters:
other- The other dateTime value- Returns:
- 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 unknown timezone are considered to be UTC values (the Comparable interface requires a total ordering).
- Throws:
java.lang.ClassCastException- if the other value is not a TimeValue (the parameter is declared as Object to satisfy the Comparable interface)
-
compareTo
public int compareTo(CalendarValue other, int implicitTimezone) throws NoDynamicContextException
Compare the value to another dateTime value- Specified by:
compareToin classCalendarValue- Parameters:
other- The other dateTime valueimplicitTimezone- The implicit timezone assumed for a value with no timezone- Returns:
- 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 unknown timezone are considered to be UTC values (the Comparable interface requires a total ordering).
- Throws:
java.lang.ClassCastException- if the other value is not a DateTimeValue (the parameter is declared as Object to satisfy the Comparable interface)NoDynamicContextException- if the implicit timezone is required and is not available (because the function is called at compile time)
-
getSchemaComparable
public java.lang.Comparable getSchemaComparable()
Description copied from class:AtomicValueGet a Comparable value that implements the XML Schema ordering comparison semantics for this value. An implementation must be provided for all atomic types.In the case of data types that are partially ordered, the returned Comparable extends the standard semantics of the compareTo() method by returning the value
SequenceTool.INDETERMINATE_ORDERINGwhen there is no defined order relationship between two given values. This value is also returned when two values of different types are compared.- Specified by:
getSchemaComparablein interfaceAtomicSequence- Specified by:
getSchemaComparablein classAtomicValue- Returns:
- a Comparable that follows XML Schema comparison rules
-
equals
public boolean equals(java.lang.Object other)
Description copied from class:AtomicValueThe equals() methods on atomic values is defined to follow the semantics of eq when applied to two atomic values. When the other operand is not an atomic value, the result is undefined (may be false, may be an exception). When the other operand is an atomic value that cannot be compared with this one, the method must throw a ClassCastException.The hashCode() method is consistent with equals().
- Specified by:
equalsin classAtomicValue- Parameters:
other- the other value- Returns:
- true if the other operand is an atomic value and the two values are equal as defined by the XPath eq operator
-
hashCode
public int hashCode()
- Overrides:
hashCodein classjava.lang.Object
-
add
public TimeValue add(DurationValue duration) throws XPathException
Add a duration to a dateTime- Specified by:
addin classCalendarValue- Parameters:
duration- the duration to be added (may be negative)- Returns:
- the new date
- Throws:
XPathException- if the duration is an xs:duration, as distinct from a subclass thereof
-
subtract
public DayTimeDurationValue subtract(CalendarValue other, XPathContext context) throws XPathException
Determine the difference between two points in time, as a duration- Overrides:
subtractin classCalendarValue- Parameters:
other- the other point in timecontext- XPath dynamic evaluation context- Returns:
- the duration as an xs:dayTimeDuration
- Throws:
XPathException- for example if one value is a date and the other is a time
