Class BulkEditValueMap

  • All Implemented Interfaces:
    Map<String,​Object>, ValueMap

    public class BulkEditValueMap
    extends Object
    implements ValueMap
    BulkEditValueMap is a ValueMap specific to the needs of Bulk Editing. It is aimed at merging the given Resources' ValueMaps.

    Please not that the merge is actually "virtual" since under the hood the ValueMap will always be empty. In other words, get(Object key) performs an on-demand merge for the passed key.

    In addition to providing the actual (merged) value for a given key, this specific ValueMap can also tell if a given key has a mixed value using #get(key + Field.IS_MIXED_SUFFIX).

    • Method Detail

      • get

        public Object get​(Object key)
        Retrieves the merged value for the passed key. Calling #get(key + Field.IS_MIXED_SUFFIX) returns true if the value is mixed; false otherwise. If the value is non-existent null is returned.
        Specified by:
        get in interface Map<String,​Object>
        Parameters:
        key - The key of the value to retrieve.
        Returns:
        The merged value for the passed key; or a boolean telling if the value is mixed or not (if the key ends with Field.IS_MIXED_SUFFIX).
      • get

        public <T> T get​(@Nonnull
                         String name,
                         @Nonnull
                         Class<T> type)
        Description copied from interface: ValueMap
        Get a named property and convert it into the given type. This method does not support conversion into a primitive type or an array of a primitive type. It should return null in this case.
        Specified by:
        get in interface ValueMap
        Type Parameters:
        T - The class of the type
        Parameters:
        name - The name of the property
        type - The class of the type
        Returns:
        Return named value converted to type T or null if non existing or can't be converted.
      • get

        @Nonnull
        public <T> T get​(@Nonnull
                         String name,
                         @Nonnull
                         T defaultValue)
        Description copied from interface: ValueMap
        Get a named property and convert it into the given type. This method does not support conversion into a primitive type or an array of a primitive type. It should return the default value in this case.

        Implementation hint: In the past it was allowed to call this with a 2nd parameter being null. Therefore all implementations should internally call Map.get(Object) when the 2nd parameter has value null.
        Specified by:
        get in interface ValueMap
        Type Parameters:
        T - The expected type
        Parameters:
        name - The name of the property
        defaultValue - The default value to use if the named property does not exist or cannot be converted to the requested type. The default value is also used to define the type to convert the value to. Must not be null. If you want to return null by default rather rely on ValueMap.get(String, Class).
        Returns:
        Return named value converted to type T or the default value if non existing or can't be converted.
