UntypedAtomicValue

public UntypedAtomicValue(String value)

Method Detail

getType

public int getType()

Description copied from interface: Indexable

Returns the type of the Indexable as one of the constants defined in 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

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

startsWith

public boolean startsWith(Collator collator,
                          AtomicValue other)
                   throws XPathException

Description copied from class: AtomicValue

Compares this atomic value to another. Returns true if the current value is of type string and its value starts with the string value of the other value.

Overrides:

startsWith in class AtomicValue

Parameters:

collator - Collator used for string comparison.

Throws:

XPathException - if this is not a string.

endsWith

public boolean endsWith(Collator collator,
                        AtomicValue other)
                 throws XPathException

Description copied from class: AtomicValue

Compares this atomic value to another. Returns true if the current value is of type string and its value ends with the string value of the other value.

Overrides:

endsWith in class AtomicValue

Parameters:

collator - Collator used for string comparison.

Throws:

XPathException - if this is not a string.

contains

public boolean contains(Collator collator,
                        AtomicValue other)
                 throws XPathException

Description copied from class: AtomicValue

Compares this atomic value to another. Returns true if the current value is of type string and its value contains the string value of the other value.

Overrides:

contains in class AtomicValue

Parameters:

collator - Collator used for string comparison.
