Simple Shared Properties

The ComponentFile Class specifies a Simple Shared Property named Files which returns the names of all the Component Files in the current directory.

The previous examples have illustrated the use of Instance Properties. It is also possible to define Shared properties.

A Shared property may be used to handle information that is relevant to the Class as a whole, and which is not specific to any a particular Instance.

    :Property Files
    :Access Public Shared
        ∇ r←get
          r←⎕FLIB''
        ∇
    :EndProperty

Note that ⎕FLIB (invoked by the Files get function) does not report the names of tied files.

      F1←⎕NEW ComponentFile 'test1'
      ⎕EX'F1'      
      F2←⎕NEW ComponentFile 'test2'
      F2.Files ⍝ NB ⎕FLIB does not report tied files
test1
      ⎕EX'F2'

Note that a Shared Property may be accessed from the Class itself. It is not necessary to create an Instance first.

      ComponentFile.Files
test1
test2
