Method Detail

getStringValue

public 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 interface Sequence

Specified by:

getStringValue in class ComputableValue

Throws:

XPathException

effectiveBooleanValue

public boolean effectiveBooleanValue()
                              throws XPathException
