Module `class.proxy_table`

allows the creation of a "proxy" for a real table or structure of tables which prevents modification but inheriting the values of the parent table.

constructor accepts a custom function for handling attempts to change the value of fields. Defaults to an error message.

This works with a given tree of tables. But note it does not protect classes within the table from being modified.

Functions

set_field_override (proxy, key, value)	sets an override on the proxy's fields.
new (table, newindex_handling_func)	create a new proxy table
is_proxy (value)	check if its a proxy table

set_field_override (proxy, key, value)

sets an override on the proxy's fields. You can use this in the newindex_handling_func param to allow proxy tables to be modified

new (table, newindex_handling_func)

create a new proxy table

table table to create immutable interface for
newindex_handling_func functions function(proxy, original_object, key, value) to call when the proxy table has an attempted set

Proxy table

is_proxy (value)

check if its a proxy table
