Enum Constant Detail

OPTIMIZED

public static final ContextTrampoline.Propagation OPTIMIZED

Default propagation option that is optimized for performance

The logic is the following:

1. Apply context variables from the snapshot
2. Execute code
3. Reset context variables

STRICT

public static final ContextTrampoline.Propagation STRICT

Pessimistic propagation option for rare cases when thread might have its own default values of the context variables and they must be restored.

The logic is the following:

1. Save context variables from the current thread
2. Apply context variables from the snapshot
3. Execute code
4. Restore context variables saved in the step [1]

Method Detail

values

public static ContextTrampoline.Propagation[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ContextTrampoline.Propagation c : ContextTrampoline.Propagation.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ContextTrampoline.Propagation valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
