Interface DataContainer

All Known Implementing Classes:

AnalysisContainer, DynamicDataContainer, PlayerContainer, RawDataContainer, ServerContainer, Session, SupplierDataContainer

public interface DataContainer

Interface for an object that can store arbitrary data referenced via Key objects.

Implementations should mainly be concerned on how the data given to it is stored. Retrieval has some details that should be followed.

Method Detail

mapToNormalMap

default java.util.Map<java.lang.String,java.lang.Object> mapToNormalMap()

handleList

default java.util.List<?> handleList(java.util.List<?> list)

handleMap

default java.util.Map<?,?> handleMap(java.util.Map<?,?> map)

putRawData

<T> void putRawData(Key<T> key,
                    T obj)

Place your data inside the container.

What the container does with the object depends on the implementation.

Type Parameters:

T - Type of the object

Parameters:

key - Key of type T that identifies the data and will be used later when the data needs to be fetched.

obj - object to store

putSupplier

<T> void putSupplier(Key<T> key,
                     java.util.function.Supplier<T> supplier)

Place a data supplier inside the container.

What the container does with the supplier depends on the implementation.

Type Parameters:

T - Type of the object

Parameters:

key - Key of type T that identifies the data and will be used later when the data needs to be fetched.

supplier - Supplier to store

putCachingSupplier

<T> void putCachingSupplier(Key<T> key,
                            java.util.function.Supplier<T> supplier)

Place a caching data supplier inside the container.

If the supplier is called the value is cached according to the implementation of the container. What the container does with the supplier depends on the implementation.

Type Parameters:

T - Type of the object

Parameters:

key - Key of type T that identifies the data and will be used later when the data needs to be fetched.

supplier - Supplier to store

supports

<T> boolean supports(Key<T> key)

Check if a Value with the given Key has been placed into the container.

Type Parameters:

T - Type of the object returned by the Value if it is present.

Parameters:

key - Key that identifies the data.

Returns:

true if found, false if not.

getValue

<T> java.util.Optional<T> getValue(Key<T> key)

Get an Optional of the Value identified by the Key.

It is recommended to check if the Optional is present as null values will be empty.

Type Parameters:

T - Type of the object returned by Value

Parameters:

key - Key that identifies the Value

Returns:

Optional of the object if the key is registered and key matches the type of the object. Otherwise empty.

getUnsafe

<T> T getUnsafe(Key<T> key)

Get data identified by the Key, or throw an exception.

It is recommended to use supports(Key) before using this method.

Type Parameters:

T - Type of the object returned by Value

Parameters:

key - Key that identifies the Value

Returns:

the value

Throws:

java.lang.IllegalArgumentException - If the key is not supported.

getFormatted

default <T> java.lang.String getFormatted(Key<T> key,
                                          Formatter<java.util.Optional<T>> formatter)

Get formatted Value identified by the Key.

Type Parameters:

T - Type of the object returned by Value

Parameters:

key - Key that identifies the Value

formatter - Formatter for the Optional returned by getValue(Key)

Returns:

Optional of the object if the key is registered and key matches the type of the object. Otherwise empty.

getFormattedUnsafe

default <T> java.lang.String getFormattedUnsafe(Key<T> key,
                                                Formatter<T> formatter)

Get formatted Value identified by the Key, or throw an exception.

It is recommended to use supports(Key) before using this method.

Type Parameters:

T - Type of the object returned by Value

Parameters:

key - Key that identifies the Value

formatter - Formatter for the value

Returns:

the value

Throws:

java.lang.IllegalArgumentException - If the key is not supported.

putAll

void putAll(DataContainer dataContainer)

Place all values from given DataContainer into this container.

Parameters:

dataContainer - Container with values.

clear

void clear()

Clear the container of all data.

getMap

java.util.Map<Key,java.lang.Object> getMap()

Return a Key - Value Map of the data in the container.

This method may call blocking methods if underlying implementation uses the given Suppliers.

Returns:

Map: Key - Object
