Method Detail

escape

public static String escape(String uri)

This function accepts a String representation of an xs:anyURI and applies the escaping method described in Section 5.4 of XML Linking (http://www.w3.org/TR/2000/PR-xlink-20001220/#link-locators) to turn it into a valid URI

Parameters:

uri - The xs:anyURI to escape into a valid URI

Returns:

An escaped string representation of the provided xs:anyURI

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 Indexable

Specified by:

getType in interface Item

Overrides:

getType in class AtomicValue

Returns:

Type of the Indexable

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 AtomicValue

Throws:

XPathException

effectiveBooleanValue

public boolean effectiveBooleanValue()
                              throws XPathException

Description copied from interface: Sequence

Get the effective boolean value of this sequence. Will be false if the sequence is empty, true otherwise.

Specified by:

effectiveBooleanValue in interface Sequence

Overrides:

effectiveBooleanValue in class AtomicValue

Throws:

XPathException

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 interface Sequence

Specified by:

convertTo in class AtomicValue

Parameters:

requiredType - one of the type constants defined in class Type

Throws:

XPathException
