Constructor Detail

JavaObjectValue

public JavaObjectValue(java.lang.Object object)
Method Detail

getType

public int getType()
Description copied from interface: Item
Return the type of this item according to the type constants defined in class Type.

Specified by:
getType in interface Item
Overrides:
getType in class AtomicValue

getObject

public java.lang.Object getObject()

getStringValue

public java.lang.String getStringValue()
Description copied from interface: Item
Return the string value of this item (see the definition of string value in XPath).

Specified by:
getStringValue in interface Item
Specified by:
getStringValue in class AtomicValue

convertTo

public AtomicValue convertTo(int requiredType)
                      throws XPathException
Description copied from interface: Item
Convert this item into an atomic value, whose type corresponds to the specified target type. requiredType should be one of the type constants defined in Type. An XPathException is thrown if the conversion is impossible.

Specified by:
convertTo in interface Item
Specified by:
convertTo in class AtomicValue
Throws:
XPathException

compareTo

public boolean compareTo(java.text.Collator collator,
                         int operator,
                         AtomicValue other)
                  throws XPathException
Specified by:
compareTo in class AtomicValue
Throws:
XPathException

compareTo

public int compareTo(java.text.Collator collator,
                     AtomicValue other)
              throws XPathException
Specified by:
compareTo in class AtomicValue
Throws:
XPathException

max

public AtomicValue max(java.text.Collator collator,
                       AtomicValue other)
                throws XPathException
Specified by:
max in class AtomicValue
Throws:
XPathException

min

public AtomicValue min(java.text.Collator collator,
                       AtomicValue other)
                throws XPathException
Specified by:
min in class AtomicValue
Throws:
XPathException

conversionPreference

public int conversionPreference(java.lang.Class javaClass)
Description copied from interface: Sequence
Returns a preference indicator, indicating the preference of a value to be converted into the given Java class. Low numbers mean that the value can be easily converted into the given class.

Specified by:
conversionPreference in interface Item
Overrides:
conversionPreference in class AtomicValue

toJavaObject

public java.lang.Object toJavaObject(java.lang.Class target)
                              throws XPathException
Description copied from interface: Sequence
Convert the value into an instance of the specified Java class.

Specified by:
toJavaObject in interface Item
Overrides:
toJavaObject in class AtomicValue
Throws:
XPathException
