ToLiteral(bool, INodeFactory)

Creates a new Boolean typed literal.

Declaration

public static ILiteralNode ToLiteral(this bool b, INodeFactory factory)

Parameters

Type	Name	Description
System.Boolean	b	Boolean.
INodeFactory	factory	Node Factory to use for Node creation.

ToLiteral(byte, INodeFactory)

Creates a new Byte typed literal.

Declaration

public static ILiteralNode ToLiteral(this byte b, INodeFactory factory)

Parameters

Type	Name	Description
byte	b	Byte.
INodeFactory	factory	Node Factory to use for Node creation.

Returns

Type	Description
ILiteralNode	Literal representing the byte.

Remarks

Byte in .Net is actually equivalent to Unsigned Byte in XML Schema so depending on the value of the Byte the type will either be xsd:byte if it fits or xsd:usignedByte.
