Kernel::GenericInterface::Mapping::Simple - GenericInterface simple data mapping backend

PUBLIC INTERFACE#

new()#

usually, you want to create an instance of this by using Kernel::GenericInterface::Mapping->new();

Map()#

provides 1:1 and regex mapping for keys and values also the use of a default for keys and values that were not mapped is possible

we need the config to be in the following format

$Self->{MappingConfig}->{Config} = {
    KeyMapExact => {           # optional. key/value pairs for direct replacement
        'old_value'         => 'new_value',
        'another_old_value' => 'another_new_value',
        'maps_to_same_value => 'another_new_value',
    },
    KeyMapRegEx => {           # optional. replace keys with value if current key matches regex
        'Stat(e|us)'  => 'state',
        '[pP]riority' => 'prio',
    },
    KeyMapDefault => {         # required. replace keys if the have not been replaced before
        MapType => 'Keep',     # possible values are
                               # 'Keep' (leave unchanged)
                               # 'Ignore' (drop key/value pair)
                               # 'MapTo' (use provided value as default)
        MapTo => 'new_value',  # only used if 'MapType' is 'MapTo'. then required
    },
    ValueMap => {              # optional.
        'new_key_name' => {    # optional. Replacement for a specific key
            ValueMapExact => { # optional. key/value pairs for direct replacement
                'old_value'         => 'new_value',
                'another_old_value' => 'another_new_value',
                'maps_to_same_value => 'another_new_value',
            },
            ValueMapRegEx => { # optional. replace keys with value if current key matches regex
                'Stat(e|us)'  => 'state',
                '[pP]riority' => 'prio',
            },
        },
    },
    ValueMapDefault => {       # required. replace keys if the have not been replaced before
        MapType => 'Keep',     # possible values are
                               # 'Keep' (leave unchanged)
                               # 'Ignore' (drop key/value pair)
                               # 'MapTo' (use provided value as default)
        MapTo => 'new_value',  # only used if 'MapType' is 'MapTo'. then required
    },
};

my $ReturnData = $MappingObject->Map(
    Data => {
        'original_key' => 'original_value',
        'another_key'  => 'next_value',
    },
);

my $ReturnData = {
    'changed_key'          => 'changed_value',
    'original_key'         => 'another_changed_value',
    'another_original_key' => 'default_value',
    'default_key'          => 'changed_value',
};

_ConfigCheck()#

does checks to make sure the config is sane

my $Return = $MappingObject->_ConfigCheck(
    Config => { # config as defined for Map
        ...
    },
);

in case of an error

$Return => {
    Success      => 0,
    ErrorMessage => 'An error occurred',
};

in case of a success

$Return = {
    Success => 1,
};
