MISSING
public static final BackpressureStrategy MISSING
TheonNext
events are written without any buffering or dropping. Downstream has to deal with any overflow.Useful when one applies one of the custom-parameter onBackpressureXXX operators.
-
ERROR
public static final BackpressureStrategy ERROR
Signals aMissingBackpressureException
in case the downstream can't keep up.
-
BUFFER
public static final BackpressureStrategy BUFFER
Buffers allonNext
values until the downstream consumes it.
-
DROP
public static final BackpressureStrategy DROP
Drops the most recentonNext
value if the downstream can't keep up.
-
LATEST
public static final BackpressureStrategy LATEST
Keeps only the latestonNext
value, overwriting any previous value if the downstream can't keep up.

values
public static BackpressureStrategy[] 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 (BackpressureStrategy c : BackpressureStrategy.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static BackpressureStrategy valueOf(java.lang.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:
java.lang.IllegalArgumentException
- if this enum type has no constant with the specified namejava.lang.NullPointerException
- if the argument is null
