Class Method Details

.Array(*args) ⇒ Object

Convenience function for creating a new Array. See Saxon::XDM::Array.create

# File 'lib/saxon/xdm.rb', line 32

def Array(*args)
  XDM::Array.create(*args)
end

.AtomicValue(*args) ⇒ Object

Convenience function for creating a new AtomicValue. See Saxon::XDM::AtomicValue.create

# File 'lib/saxon/xdm.rb', line 17

def AtomicValue(*args)
  XDM::AtomicValue.create(*args)
end

.EmptySequence ⇒ Object

Returns the XDM EmptySequence. See Saxon::XDM::EmptySequence.create



27
28
29
 
# File 'lib/saxon/xdm.rb', line 27

def EmptySequence()
  XDM::EmptySequence.create
end

.Item(item) ⇒ Object

Create one of the XdmItem-derived XDM objects from the passed in argument.

Existing XDM::* objects are passed through. s9api.Xdm* Java objects are wrapped appropriately and returned. Ruby Arrays and Hashes are converted to Array and Map instances respectively. Ruby values that respond to #each are converted to an Array (e.g. Set). Other Ruby values are converted to AtomicValue.
