Method Detail

getType

public XQItemType getType()
                   throws XQEvalException

Description copied from interface: XQItem

Returns the type description.

Throws:

XQEvalException

isNode

public boolean isNode()

Description copied from interface: XQItem

Tests whether the item is a Node.

getNode

public abstract XQNode getNode()
                        throws XQEvalException

Description copied from interface: XQItem

Gets the item as a Node value.

Throws:

XQEvalException

getItem

public XQItem getItem()
               throws XQEvalException

Description copied from interface: XQValue

Gets the current item (undefined result if end of sequence reached).

Throws:

XQEvalException

asAtom

public XQItem asAtom()
              throws XQEvalException

Description copied from interface: XQValue

Gets the current item with atomization. If the current item is a Node, it is transparently transformed into a sequence of atomic values (in the future schema-aware implementation), or simply to its string value (in XQuery Basic).

Throws:

XQEvalException

getBoolean

public boolean getBoolean()
                   throws XQEvalException

Description copied from interface: XQItem

Gets the item as a boolean value.

Throws:

XQEvalException

getString

public java.lang.String getString()
                           throws XQEvalException

Description copied from interface: XQItem

Gets the item as a String value.

Throws:

XQEvalException

getInteger

public long getInteger()
                throws XQEvalException

Description copied from interface: XQItem

Gets the item as a integer value.

Throws:

XQEvalException

getDouble

public double getDouble()
                 throws XQEvalException

Description copied from interface: XQItem

Gets the item as a double value.

Throws:

XQEvalException

compareTo

public int compareTo(XQItem that,
                     java.text.Collator collator,
                     int implicitTimeZone)
              throws XQEvalException

Description copied from interface: XQItem

Compares two items.

Throws:

XQEvalException
