Method Detail

isEqual

public boolean isEqual(LiteralLabel value1,
                       LiteralLabel value2)

Compares two instances of values of the given datatype. This ignores lang tags and just uses the java.lang.Number equality.

Specified by:

isEqual in interface RDFDatatype

Overrides:

isEqual in class XSDDatatype

isDigit

public static final boolean isDigit(char ch)

getDigit

public static final int getDigit(char ch)

dateToString

public String dateToString(int[] date)

appendFractionalTime

public static void appendFractionalTime(StringBuffer buff,
                                        int fsec,
                                        int scale)

Append the fraction time part of a date/time vector to a string buffer.

normalizeSubType

public RDFDatatype normalizeSubType(Object value,
                                    RDFDatatype dt)

Normalization. If the value is narrower than the current data type (e.g. value is xsd:date but the time is xsd:datetime) returns the narrower type for the literal. If the type is narrower than the value then it may normalize the value (e.g. set the mask of an XSDDateTime) Currently only used to narrow gener XSDDateTime objects to the minimal XSD date/time type.

Specified by:

normalizeSubType in interface RDFDatatype

Overrides:

normalizeSubType in class BaseDatatype

Parameters:

value - the current object value

dt - the currently set data type

Returns:

a narrower version of the datatype based on the actual value range
