Method Detail

get

@Deprecated
default <T> T get(@NotNull
                              @NotNull DataKey<T> key)

Deprecated. use key.get(dataHolder) instead, which will do the same thing an carries nullable information for the data

Get the given key, if it does not exist then use the key's factory to create a new value and put it into the collection so that the following get of the same key will find a value

Specified by:

get in interface DataHolder

Type Parameters:

T - Type returned by key

Parameters:

key - data key

Returns:

return stored value or newly created value

getOrCompute

Object getOrCompute(@NotNull
                    @NotNull DataKeyBase<?> key,
                    @NotNull
                    @NotNull DataValueFactory<?> factory)

Description copied from interface: DataHolder

Get key if it exists or compute using supplier

Method used by DataKey classes to access data.

NOTE: MutableDataHolders will compute an absent key and add it to its dataSet. DataHolders will return computed value but not change contained dataSet because they are immutable. So value will be computed every time it is requested.

Specified by:

getOrCompute in interface DataHolder

Parameters:

key - data key

factory - factory taking this data holder and computing/providing default value

Returns:

object value for the key

set

@NotNull
<T> @NotNull MutableDataHolder set(@NotNull
                                            @NotNull DataKey<T> key,
                                            @NotNull
                                            T value)

Store the given value for the key

Type Parameters:

T - data type of the data referred by the key

Parameters:

key - data key

value - value to store

Returns:

mutable data holder for chained calls

set

@NotNull
<T> @NotNull MutableDataHolder set(@NotNull
                                            @NotNull NullableDataKey<T> key,
                                            @Nullable
                                            T value)

Store the given value for the key

Type Parameters:

T - data type of the data referred by the key

Parameters:

key - data key

value - value to store

Returns:

mutable data holder for chained calls

remove

@NotNull
@NotNull MutableDataHolder remove(@NotNull
                                           @NotNull DataKeyBase<?> key)

Remove the stored value for the key, used to force to default or to force recompute

Parameters:

key - data key to remove

Returns:

mutable data holder for chained calls

setFrom

@NotNull
@NotNull MutableDataHolder setFrom(@NotNull
                                            @NotNull MutableDataSetter dataSetter)

Store the given value for the key

Parameters:

dataSetter - data setter which will set values

Returns:

mutable data holder for chained calls

setAll

@NotNull
@NotNull MutableDataHolder setAll(@NotNull
                                           @NotNull DataHolder other)

Copy all values from one data holder to this data holder

Parameters:

other - data holder from which to copy all values

Returns:

mutable data holder for chained calls

setIn

@NotNull
@NotNull MutableDataHolder setIn(@NotNull
                                          @NotNull MutableDataHolder dataHolder)

Set options in given mutable data holder

Specified by:

setIn in interface DataHolder

Specified by:
