Method Detail

getStringValue

public java.lang.String getStringValue()
                                throws XPathException
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 ComputableValue
Throws:
XPathException

effectiveBooleanValue

public boolean effectiveBooleanValue()
                              throws XPathException
