Enum WriteObjectFlags

java.lang.Object

java.lang.Enum<WriteObjectFlags>

org.apache.hadoop.fs.s3a.impl.write.WriteObjectFlags

All Implemented Interfaces:

Serializable, Comparable<WriteObjectFlags>

public enum WriteObjectFlags
extends Enum<WriteObjectFlags>

Flags to use when creating/writing objects. The configuration key is used in two places:

1. Parsing builder options
2. hasCapability() probes of the output stream.

Method Detail

values

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

Returns:

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

valueOf

public static WriteObjectFlags 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

isEnabled

public boolean isEnabled(org.apache.hadoop.conf.Configuration options)

does the configuration contain this option as a boolean?

Parameters:

options - options to scan

Returns:

true if this is defined as a boolean

hasKey

public boolean hasKey(String k)

Does the key of this option match the parameter?

Parameters:

k - key

Returns:

true if there is a match.
