Method Detail

of

public static <T> Ref<T> of(T value)

Construct a new mutable Ref instance referencing the given input value.

Type Parameters:

T - type of the referenced instance.

Parameters:

value - value of the newly constructed reference.

Returns:

a new mutable Ref instance referencing the given input value.

emptyRef

public static <T> Ref<T> emptyRef()

Construct a new empty mutable Ref instance.

Type Parameters:

T - type of the referenced instance.

Returns:

a new mutable empty Ref instance.

threadSafe

public static <T> Ref<T> threadSafe()

Construct a new empty mutable thread-safe Ref instance.

Type Parameters:

T - type of the referenced instance.

Returns:

a new mutable empty thread-safe Ref instance.

Since:

2.8

threadSafe

public static <T> Ref<T> threadSafe(T value)

Construct a new mutable thread-safe Ref instance referencing the given input value.

Type Parameters:

T - type of the referenced instance.

Parameters:

value - value of the newly constructed reference.

Returns:

a new mutable thread-safe Ref instance referencing the given input value.

Since:

2.8

immutableRef

public static <T> Ref<T> immutableRef(T value)
