itemcontainer.makeconst - Function

	Package	utility
	Module	misc
	Tool	itemcontainer

Make this itemcontainer const

Synopsis
makeconst()

Returns
Boolean

Description
After application of this tool function, you can no longer change the internal state of the itemcontainer tool.

Example

- i1 := itemcontainer();
T
- i1.set('par1', 20);
T
- i1.set('par2', 30);
T
- i1.makeconst();
T
- i1.set('par3', 40);
This is a const tool, you cannot overwrite it
<fail>: This is a const object, you cannot overwrite it
        File:   itemcontainer.g, Line 56
        Stack:  .()

Note that this is a different error from

- const i1 := itemcontainer()
- i1 := 'fish'
<fail>: <fail>: 'const' values cannot be modified.

Here Glish is complaining that it can't reassign the tool i1. The previous example is illustrating that after application of the makeconst function, you can't change the internal state of the itemcontainer tool (nothing to do with trying to overwrite it).
