The empty context (immutable).

Method Details

of

public static <T> IContext of(Property<T> property,
 T value)

Returns an immutable context containing only the given property-value binding.

Type Parameters:

T - type of value

Parameters:

property - not null

value - may be null

Returns:

an immutable context containing only the given property-value binding (never null)

of

public static <T> IContext of(Class<T> clazz,
 T value)

Returns an immutable context containing only the given class-value binding.

Type Parameters:

T - type of value

Parameters:

clazz - not null

value - may be null

Returns:

an immutable context containing only the given class-value binding (never null)

with

public static IContext with(IContext... contexts)

Returns a new context that combines the given contexts in the specified order.

The returned context is immutable provided that each of the given contexts is immutable. If some of the given contexts are not immutable, the returned context is neither immutable nor thread-safe.

Parameters:

contexts - the contexts to combine

Returns:

the combined context (never null)

with

public static IContext with(List<IContext> contexts)

Returns a new context that combines the given contexts in the specified order.

The returned context is immutable provided that each of the given contexts is immutable. If some of the given contexts are not immutable, the returned context is neither immutable nor thread-safe.

Parameters:

contexts - the contexts to combine

Returns:

the combined context (never null)
