Validate

The validation table contains a suite of functions that can provide input validation for other scripts. A validation function, when provided with a value, checks that value and returns true if it passes the check. If the value does not pass the check then the validation function throws a script_error containing a descriptive error message and return false.

The diference between calling a validation function and calling one of the global Lua Type Checking functions is that the validation function will automatically throw a script error if the validation fails.

Parameters:

1

value

value

Parameters:

1

value

value

Returns:

value

value

defined in ../../Warhammer/working_data/script/_lib/lib_types.lua, line 1958

validate.is_non_empty_table(value value)
Throws a script_error and returns false if the supplied value is not a non-empty table. If the supplied value is considered to be a non-empty indexed table then true is returned.

Parameters:

1

value

value

Returns:

  1. boolean value is a non-empty table

defined in ../../Warhammer/working_data/script/_lib/lib_types.lua, line 1965

validate.is_non_empty_table_indexed(value value)
Throws a script_error and returns false if the supplied value is not a non-empty indexed table. An indexed table contains values stored in elements with keys which are ascending integer numbers, starting at 1. Values stored at keys that are not ascending integers are not queried by this test, so a table that contains only values stored in elements with string keys will not count as a "non empty table indexed". If the supplied value is considered to be a non-empty indexed table then true is returned.

Parameters:

1

value

value

Returns:

  1. boolean value is a non-empty indexed table

defined in ../../Warhammer/working_data/script/_lib/lib_types.lua, line 1980

If the supplied value is a condition then true is returned.

Parameters:
