DESCRIPTION

Mo utilities for checking of data objects.

SUBROUTINES

`check_angle`

check_angle($self, $key);

Since version 0.20.

Check parameter defined by $key which is number between 0 and 360.

Put error if check isn't ok.

Returns undef.

`check_array`

check_array($self, $key);

Since version 0.06.

Check parameter defined by $key which is reference to array.

Put error if check isn't ok.

Returns undef.

`check_array_object`

check_array_object($self, $key, $class, $class_name);

Since version 0.02. Described functionality since version 0.21.

Check parameter defined by $key which is reference to array with instances of some object type ($class). $class_name is used to error message.

Put error if check isn't ok.

Returns undef.

`check_array_required`

check_array_required($self, $key);

Since version 0.18. Described functionality since version 0.19.

Check parameter defined by $key which is reference to array for at least one value inside.

Put error if check isn't ok.

Returns undef.

`check_bool`

check_bool($self, $key);

Since version 0.06.

Check parameter defined by $key if value is bool or not.

Put error if check isn't ok.

Returns undef.

`check_code`
