Class ObjectValue

    • Constructor Detail

      • ObjectValue

        public ObjectValue()
        Default constructor for use in subclasses
      • ObjectValue

        public ObjectValue​(java.lang.Object object)
        Constructor
        Parameters:
        object - the object to be encapsulated
    • Method Detail

      • setValue

        public void setValue​(java.lang.Object value)
        Set the value in this object value
      • convertPrimitive

        public AtomicValue convertPrimitive​(BuiltInAtomicType requiredType,
                                            boolean validate,
                                            XPathContext context)
        Convert to target data type
        Specified by:
        convertPrimitive in class AtomicValue
        Parameters:
        requiredType - type code of the required atomic type
        validate - true if validation is required. If set to false, the caller guarantees that the value is valid for the target data type, and that further validation is therefore not required. Note that a validation failure may be reported even if validation was not requested.
        context - The conversion context to be used. This is required at present only when converting to a date or time: it provides the implicit timezone.
        Returns:
        the result of the conversion, if successful. If unsuccessful, the value returned will be a ValidationErrorValue. The caller must check for this condition. No exception is thrown, instead the exception will be encapsulated within the ValidationErrorValue.
      • effectiveBooleanValue

        public boolean effectiveBooleanValue​(XPathContext context)
                                      throws XPathException
        Get the effective boolean value of the value
        Specified by:
        effectiveBooleanValue in interface Expression
        Overrides:
        effectiveBooleanValue in class AtomicValue
        Parameters:
        context - the evaluation context (not used in this implementation)
        Returns:
        true, unless the value is boolean false, numeric zero, or zero-length string
        Throws:
        XPathException - if any dynamic error occurs evaluating the expression
      • getObject

        public java.lang.Object getObject()
        Get the encapsulated object
      • equals

        public boolean equals​(java.lang.Object other)
        Determine if two ObjectValues are equal
        Overrides:
        equals in class Value
        Throws:
        java.lang.ClassCastException - if they are not comparable
      • hashCode

        public int hashCode()
        Description copied from class: Value
        Return a hash code to support the equals() function
        Overrides:
        hashCode in class Value
