35 * Contains key-value pairs (elements) where keys are "displayable" |

36 * keys which the IDE can display/choose and values are "identifier" values |

37 * which can be stored in parameters' map. |

40 * to LSApplicationCategoryType which is required for the mac app store. |

|
43 * the MAC_CATEGORY parameter: |
|
44 * |
|
45 * <pre>{@code |
|
46 * Set<String> keys = MAC_CATEGORY.getDisplayableKeys(); |
|
47 * |
|
48 * String key = getLastValue(keys); // get last value for example |
|
49 * |
|
50 * String value = MAC_CATEGORY.getValueForDisplayableKey(key); |
|
51 * params.put(MAC_CATEGORY.getID(), value); |
