public class ValueFactory
extends Object

Static methods to create Xdm values.

Method Summary

static XdmSequence	cast(XdmSequence seq, Class<? extends XS_AnyType> targetClass, SequenceType.OccurrenceIndicator occurence, StaticXQueryContext context) Creates a new XdmSequence by casting the elements in the original sequence.
static XS_AnySimpleType	castSingleValue(XdmValue value, Class<? extends XS_AnyType> targetClass) Creates a new XdmValue by casting the given value to another type.
static XdmValue	makeNumericValue(String resp) Creates a numeric value (xs:double, xs:decimal or xs:integer) from a string representation
static XS_AnyAtomicType	makeValue(QName typeName, String value) Creates a new instance of an XDM value with the given type and the given value.
static XS_AnyAtomicType	newInstance(Class<? extends XS_AnyType> targetClass, XdmValue theValue) Creates a new instance of an XDM value with the given type and the given value.

Method Detail

makeNumericValue

public static XdmValue makeNumericValue(String resp)
                                 throws XPathException

Creates a numeric value (xs:double, xs:decimal or xs:integer) from a string representation

Parameters:

resp - a string representation

Returns:

an numeric value

Throws:

XPathException - throws, if no value can be created.

cast

public static XdmSequence cast(XdmSequence seq,
                               Class<? extends XS_AnyType> targetClass,
                               SequenceType.OccurrenceIndicator occurence,
                               StaticXQueryContext context)
                        throws XPathException

Creates a new XdmSequence by casting the elements in the original sequence.

Parameters:

seq - the sequence to cast.

targetClass - the target class for the cast.

occurence - the occurrence indicator for the cast.

context - a static XQuery context for this cast.

Returns:

the casted sequences.

Throws:

XPathException - thrown, if the sequence cannot be casted.

castSingleValue

public static XS_AnySimpleType castSingleValue(XdmValue value,
                                               Class<? extends XS_AnyType> targetClass)
                                        throws XPathException

Creates a new XdmValue by casting the given value to another type.

Parameters:

value - the value to cast.

targetClass - the class to cast to.

Returns:

the casted value.

Throws:

XPathException - if the value cannot be casted.

makeValue

public static XS_AnyAtomicType makeValue(QName typeName,
                                         String value)
                                  throws XPathException

Creates a new instance of an XDM value with the given type and the given value.

Parameters:

typeName - the type name (xs:....)

value - a string representation of the value.

Returns:

the created value.

Throws:

XPathException - thrown, if no class with the given type name is found.

newInstance

public static XS_AnyAtomicType newInstance(Class<? extends XS_AnyType> targetClass,
                                           XdmValue theValue)
                                    throws XPathException

Creates a new instance of an XDM value with the given type and the given value.

Parameters:

targetClass - the class for the new value.

theValue - the value for the new value.

Returns:

the new value.

Throws:

XPathException - thrown, if the value can not be created.
