Class XdmAtomicValue 

public class XdmAtomicValue
extends XdmItem

The class XdmAtomicValue represents an item in an XPath 2.0 sequence that is an atomic value. The value may belong to any of the 19 primitive types defined in XML Schema, or to a type derived from these primitive types, or to the XPath 2.0 type xdt:untypedAtomic

Constructor Summary
XdmAtomicValue(long i)

Construct an atomic value of type xs:integer

XdmAtomicValue(decimal d)

Construct an atomic value of type xs:decimal

XdmAtomicValue(float f)

Construct an atomic value of type xs:float

XdmAtomicValue(double d)

Construct an atomic value of type xs:double

XdmAtomicValue(bool b)

Construct an atomic value of type xs:boolean

XdmAtomicValue(System.Uri u)

Construct an atomic value of type xs:anyURI

XdmAtomicValue(QName q)

Construct an atomic value of type xs:QName

XdmAtomicValue(string lexicalForm, QName type, Processor processor)

Construct an atomic value of a given built-in or user-defined type

XdmAtomicValue()
 
Property Summary
 Object Value

Get the value as a CLI object of the nearest equivalent type.
 
Method Summary
 bool IsAtomic()

Determine whether the item is an atomic value

static XdmAtomicValue wrapExternalObject(object external)

Create an atomic value that wraps an external object. Such values can be used in conjunction with extension functions. (Synonym of WrapExternalObject, retained for backwards compatibility.)

static XdmAtomicValue WrapExternalObject(object external)

Create an atomic value that wraps an external object. Such values can be used in conjunction with extension functions.

 String ToString()

Convert the atomic value to a string

 QName GetTypeName(Processor processor)

Get the name of the value's XDM type

 QName GetPrimitiveTypeName()

Get the name of the primitive type of the value

 
Constructor Detail

XdmAtomicValue

public XdmAtomicValue(long i)

Construct an atomic value of type xs:integer

Parameters:
i -
The integer value

XdmAtomicValue

public XdmAtomicValue(decimal d)

Construct an atomic value of type xs:decimal

Parameters:
d -
The decimal value

XdmAtomicValue

public XdmAtomicValue(float f)

Construct an atomic value of type xs:float

Parameters:
f -
The float value

XdmAtomicValue

public XdmAtomicValue(double d)

Construct an atomic value of type xs:double

Parameters:
d -
The double value

XdmAtomicValue

public XdmAtomicValue(bool b)

Construct an atomic value of type xs:boolean

Parameters:
b -
The boolean value

XdmAtomicValue

public XdmAtomicValue(System.Uri u)

Construct an atomic value of type xs:anyURI

Parameters:
u -
The uri value

XdmAtomicValue

public XdmAtomicValue(QName q)

Construct an atomic value of type xs:QName

Parameters:
q -
The QName value

XdmAtomicValue

public XdmAtomicValue(string lexicalForm,
                      QName type,
                      Processor processor)

Construct an atomic value of a given built-in or user-defined type

Parameters:
lexicalForm -
The string representation of the value (any value that is acceptable in the lexical space, as defined by XML Schema Part 2). Whitespace normalization as defined by the target type will be applied to the value.
type -
The QName giving the name of the target type. This must be an atomic type, and it must not be a type that is namespace-sensitive (QName, NOTATION, or types derived from these). If the type is a user-defined type then its definition must be present in the schema cache maintained by the SchemaManager.
processor -
The Processor object. This is needed for looking up user-defined types, and also because some conversions are context-sensitive, for example they depend on the implicit timezone or the choice of XML 1.0 versus XML 1.1 for validating names.

XdmAtomicValue

public XdmAtomicValue()
Property Detail

Value

public Object Value {get; }

Get the value as a CLI object of the nearest equivalent type.

The return type is as follows:

xs:string - String

xs:integer - Long

xs:decimal - Decimal

xs:double - Double

xs:float - Float

xs:boolean - Bool

xs:QName - QName

xs:anyURI - Uri

xdt:untypedAtomic - String

Other types - currently String, but this may change in the future

returns
The value converted to the most appropriate CLI type
Method Detail

IsAtomic

public bool IsAtomic()

Determine whether the item is an atomic value

returns
true (the item is an atomic value)

wrapExternalObject

public XdmAtomicValue wrapExternalObject(object external)

Create an atomic value that wraps an external object. Such values can be used in conjunction with extension functions. (Synonym of WrapExternalObject, retained for backwards compatibility.)

Parameters:
external -
The object to be wrapped.
returns
The wrapped object

WrapExternalObject

public XdmAtomicValue WrapExternalObject(object external)

Create an atomic value that wraps an external object. Such values can be used in conjunction with extension functions.

Parameters:
external -
The object to be wrapped.
returns
The wrapped object

ToString

public String ToString()

Convert the atomic value to a string

returns
The value converted to a string, according to the rules of the XPath 2.0 cast operator

GetTypeName

public QName GetTypeName(Processor processor)

Get the name of the value's XDM type

Parameters:
processor -
The Processor object. This is needed for access to the NamePool, which maps the internal form of type names to their external form.
returns
The type of the value, as a QName. This may be a built-in type or a user-defined atomic type.

GetPrimitiveTypeName

public QName GetPrimitiveTypeName()

Get the name of the primitive type of the value

returns
The primitive type of the value, as a QName. This will be the name of one of the primitive types defined in XML Schema Part 2, or the XPath-defined type xdt:untypedAtomic. For the purposes of this method, xs:integer is considered to be a primitive type.
