 net.sf.saxon.value.Value
net.sf.saxon.value.AtomicValue
net.sf.saxon.value.DurationValue
All known Subclasses: net.sf.saxon.value.SecondsDurationValue, net.sf.saxon.value.MonthDurationValue,
| DurationValue | | public class DurationValue extends AtomicValue (Code) | | A value of type xs:duration
|
| Method Summary | |
| public DurationValue | add(DurationValue other, XPathContext context)
| | protected void | badDuration(String msg, CharSequence s)
| | public AtomicValue | convertPrimitive(BuiltInAtomicType requiredType, boolean validate, XPathContext context)
| | public Object | convertToJava(Class target, XPathContext context)
| | public DecimalValue | divide(DurationValue other, XPathContext context)
| | public boolean | equals(Object other)
Test if the two durations are of equal length. | | public AtomicValue | getComponent(int component)
| | public ItemType | getItemType(TypeHierarchy th)
| | public double | getLengthInSeconds()
Get length of duration in seconds, assuming an average length of month. | | public String | getStringValue()
Convert the value to a string, using the serialization rules.
For atomic values this is the same as a cast; for sequence values
it gives a space-separated list. | | public CharSequence | getStringValueCS()
| | public int | hashCode()
| | public DurationValue | multiply(double factor, XPathContext context)
| | public DurationValue | normalizeDuration()
Normalize the duration, so that months<12, hours<24, minutes<60, seconds<60.
At present we do this when converting to a string. | | public boolean | schemaEquals(Value obj)
Compare two values for equality. | | public DurationValue | subtract(DurationValue other, XPathContext context)
|
| hours | | protected int hours(Code) | | |
| microseconds | | protected int microseconds(Code) | | |
| minutes | | protected int minutes(Code) | | |
| months | | protected int months(Code) | | |
| negative | | protected boolean negative(Code) | | |
| seconds | | protected int seconds(Code) | | |
| years | | protected int years(Code) | | |
| DurationValue | | protected DurationValue()(Code) | | Private constructor for internal use
|
| DurationValue | | public DurationValue(boolean positive, int years, int months, int days, int hours, int minutes, int seconds, int microseconds)(Code) | | |
| DurationValue | | public DurationValue(CharSequence s) throws XPathException(Code) | | Constructor: create a duration value from a supplied string, in
ISO 8601 format [+|-]PnYnMnDTnHnMnS
|
| 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 |
| equals | | public boolean equals(Object other)(Code) | | Test if the two durations are of equal length. Note: this function is defined
in XPath 2.0, but its semantics are currently unclear.
|
| getLengthInSeconds | | public double getLengthInSeconds()(Code) | | Get length of duration in seconds, assuming an average length of month. (Note, this defines a total
ordering on durations which is different from the partial order defined in XML Schema; XPath 2.0
currently avoids defining an ordering at all. But the ordering here is consistent with the ordering
of the two duration subtypes in XPath 2.0.)
|
| getStringValue | | public String getStringValue()(Code) | | Convert the value to a string, using the serialization rules.
For atomic values this is the same as a cast; for sequence values
it gives a space-separated list. This method is refined for AtomicValues
so that it never throws an Exception.
|
| getStringValueCS | | public CharSequence getStringValueCS()(Code) | | Convert to string
ISO 8601 representation. |
| hashCode | | public int hashCode()(Code) | | |
| normalizeDuration | | public DurationValue normalizeDuration()(Code) | | Normalize the duration, so that months<12, hours<24, minutes<60, seconds<60.
At present we do this when converting to a string. It's possible that it should be done immediately
on constructing the duration (so that component extraction functions get the normalized value).
We're awaiting clarification of the spec...
|
| schemaEquals | | public boolean schemaEquals(Value obj)(Code) | | Compare two values for equality. This supports the matching rules in XML Schema, which say that two
durations are equal only if all six components are equal (thus 12 months does not equal one year).
