Method Detail

newValue

public static XdmValue newValue(ValueType valueType,
                                Object value)

Generic XdmValue creation factory method. Value types are enumerated in ValueType. Examples are ValueType.XS_INTEGER, ValueType.XS_BOOLEAN, ValueType.SEQUENCE, ValueType.XS_STRING, etc.

NOTE: If you pass a valueType of ValueType.NODE, it will be treated as ValueType.ELEMENT. Using ValueType.NODE directly is discouraged, it is defined as the common super-type for all node types. Other node types that may be constructed are ValueType.TEXT and ValueType.BINARY. In future releases, creation of additional node value types will be supported.

Parameters:

valueType - An concrete subclass of ValueType which indicates the type of value to create.

value - An Object containing the actual value to construct the object with. The specific class of this object is be dependent on the valueType argument. If the provided value is not consistent with the valueType then a IllegalArgumentException may be thrown.

Returns:

An instance of XdmValue.

Throws:

IllegalArgumentException - If the provided value is not consistent with the valueType.

newElement

public static XdmElement newElement(Object value)

A convenience method to construct an XdmElement value. XdmElement objects can be constructed from an XML String, a W3C DOM Element or an InputStream.

Parameters:

value - An instance of String, Element or InputStream.

Returns:

An instance of XdmElement.

Throws:

IllegalArgumentException - If value is not a String, Element or InputStream.

newTextNode

public static XdmText newTextNode(Object value)

A convenience method to construct an XdmText value. XdmText objects can be constructed from an XML String, a W3C DOM Text node or an InputStream.

Parameters:

value - An instance of String, Text or InputStream.

Returns:

An instance of XdmText.

Throws:

IllegalArgumentException - If value is not a String, Text or InputStream.

newBinaryNode

public static XdmBinary newBinaryNode(Object value)

newXSString

public static XSString newXSString(String value)

A convenience method to construct an XSString value.

Parameters:

value - A String to construct the XSString object with.

Returns:

An instance of XSString.

newXSInteger

public static XSInteger newXSInteger(long value)

A convenience method to construct an XSInteger value. Note that an XQuery xs:integer can hold values larger than a Java int or long.

Parameters:

value - A long to construct the XSInteger object with.

Returns:

An instance of XSInteger.

newXSInteger

public static XSInteger newXSInteger(BigInteger value)

A convenience method to construct an XSInteger value. Note that an XQuery xs:integer can hold values larger than a Java int or long, but these large value may be represented with a BigInteger object.

Parameters:

value - A BigInteger to construct the XSInteger object with.

Returns:

An instance of XSInteger.

newXSBoolean

public static XSBoolean newXSBoolean(boolean value)

A convenience method to construct an XSBoolean value.

Parameters:

value - A boolean to construct the XSBoolean object with.

Returns:

An instance of XSBoolean.

newXSDateTime

public static XSDateTime newXSDateTime(String value,
                                       TimeZone timeZone,
                                       Locale locale)

A convenience method to construct an XSDateTime value.

Parameters:

value - A String representation of the date/time in standard XQuery form (ie 2006-04-23T11:32:46).

timeZone - A TimeZone object to apply to value, null for default.

locale - A Locale object to apply to the value, null for default.

Returns:

An instance of XSDateTime.

newXSDate

public static XSDate newXSDate(String value,
                               TimeZone timeZone,
                               Locale locale)

A convenience method to construct an XSDate value.

Parameters:

value - A String representation of the date/time in standard XQuery form (ie 2006-04-23).

timeZone - A TimeZone object to apply to value, null for default.

locale - A Locale object to apply to the value, null for default.

Returns:

An instance of XSDate.

newXSTime

public static XSTime newXSTime(String value,
                               TimeZone timeZone,

A convenience method to construct an XSTime value.

Parameters:

value - A String representation of the date/time in standard XQuery form (ie 11:32:46).
