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 Indexable

Specified by:

getType in interface Item

Overrides:

getType in class AtomicValue

Returns:

Type of the Indexable

getObject

public Object getObject()

getStringValue

public 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 interface Sequence

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 interface Sequence

Specified by:

convertTo in class AtomicValue

Parameters:

requiredType - one of the type constants defined in class Type

Throws:

XPathException

compareTo

public boolean compareTo(Collator collator,
                         int operator,
                         AtomicValue other)
                  throws XPathException

Specified by:

compareTo in class AtomicValue

Throws:

XPathException

compareTo

public int compareTo(Collator collator,
                     AtomicValue other)
              throws XPathException

Specified by:

compareTo in class AtomicValue

Throws:

XPathException

max

public AtomicValue max(Collator collator,
                       AtomicValue other)
                throws XPathException

Specified by:

max in class AtomicValue

Throws:

XPathException

min

public AtomicValue min(Collator collator,
                       AtomicValue other)
                throws XPathException

Specified by:

min in class AtomicValue

Throws:

XPathException

conversionPreference

public int conversionPreference(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

Specified by:

conversionPreference in interface Sequence

Overrides:

conversionPreference in class AtomicValue

toJavaObject

public Object toJavaObject(Class target)

Convert the value into an instance of the specified Java class.

Specified by:

toJavaObject in interface Item

Specified by:

toJavaObject in interface Sequence

Overrides:

toJavaObject in class AtomicValue

Throws:

XPathException
