Enum Constant Detail

DROP_LATEST

public static final BufferOverflowStrategy DROP_LATEST

Drop the new element without propagating an error when the buffer is full.

DROP_OLDEST

public static final BufferOverflowStrategy DROP_OLDEST

When the buffer is full, remove the oldest element from it and offer the new element at the end instead. Do not propagate an error.

ERROR

public static final BufferOverflowStrategy ERROR

Propagate an IllegalStateException when the buffer is full.

Method Detail

valueOf

public static BufferOverflowStrategy 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

values

public static BufferOverflowStrategy[] 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 (BufferOverflowStrategy c : BufferOverflowStrategy.values())
    System.out.println(c);

Returns:

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