Record Class Implementation<T extends Implementation.ExtensionProvidable>

java.lang.Object

java.lang.Record

com.github.kaktushose.jda.commands.extension.Implementation<T>

Record Components:

type - the Class of the implemented interface

supplier - the Function used to retrieve instances of the custom implementation

public record Implementation<T extends Implementation.ExtensionProvidable>(Class<T extends Implementation.ExtensionProvidable> type, Function<JDACBuilderData, SequencedCollection<T extends Implementation.ExtensionProvidable>> supplier)
extends Record

Instances of Implementation are used to provide custom implementations of Implementation.ExtensionProvidable interfaces, namely:

• ClassFinder
• Descriptor
• InteractionControllerInstantiator
• ErrorMessageFactory
• Implementation.MiddlewareContainer (wrapper type for Middleware)
• Implementation.TypeAdapterContainer (wrapper type for TypeAdapter)
• Implementation.ValidatorContainer (wrapper type for Validator)
• PermissionsProvider
• GuildScopeProvider

Such instances of Implementation are returned by Extension.providedImplementations() and used by the JDACBuilder to configure jda-commands.

Note: If the supplier() returns an empty collection, then this Implementation is discarded and thus treated as non-existent.

Constructor Details

Implementation

public Implementation(Class<T> type,
 Function<JDACBuilderData, SequencedCollection<T>> supplier)

Creates an instance of a Implementation record class.

Parameters:

type - the value for the type record component

supplier - the value for the supplier record component

Method Details

single

public static <T extends Implementation.ExtensionProvidable>
Implementation<T> single(Class<T> type,
 Function<JDACBuilderData, T> supplier)

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

type

public Class<T> type()

Returns the value of the type record component.

Returns:

the value of the type record component

supplier

public Function<JDACBuilderData, SequencedCollection<T>> supplier()

Returns the value of the supplier record component.

Returns:

the value of the supplier record component
