Enum ObjectInspectorFactory.ObjectInspectorOptions

java.lang.Object

java.lang.Enum<ObjectInspectorFactory.ObjectInspectorOptions>

org.apache.hadoop.hive.serde2.objectinspector.ObjectInspectorFactory.ObjectInspectorOptions

All Implemented Interfaces:

Serializable, Comparable<ObjectInspectorFactory.ObjectInspectorOptions>

Enclosing class:

ObjectInspectorFactory

public static enum ObjectInspectorFactory.ObjectInspectorOptions
extends Enum<ObjectInspectorFactory.ObjectInspectorOptions>

ObjectInspectorOptions describes what ObjectInspector to use. JAVA is to use pure JAVA reflection. THRIFT is to use JAVA reflection and filter out __isset fields, PROTOCOL_BUFFERS filters out has*. New ObjectInspectorOptions can be added here when available. We choose to use a single HashMap objectInspectorCache to cache all situations for efficiency and code simplicity. And we don't expect a case that a user need to create 2 or more different types of ObjectInspectors for the same Java type.

Method Detail

values

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

public static ObjectInspectorFactory.ObjectInspectorOptions 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
