Enum Constant Detail

DROP_OLDEST

public static final QDAgent.BufferOverflowStrategy DROP_OLDEST

Drop oldest records when buffer overflows.

DROP_NEWEST

public static final QDAgent.BufferOverflowStrategy DROP_NEWEST

Drop newest records when buffer overflows.

BLOCK

public static final QDAgent.BufferOverflowStrategy BLOCK

Block data processing when buffer overflows until buffer space is available. The QDDistributor.processData(DataIterator) method will block until buffer space in this agent becomes available. This block can be interrupted, in which case data processing aborts leaving the interrupt flag set.

Method Detail

values

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

Returns:

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

valueOf

public static QDAgent.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
