Method Detail

getPrimitiveWritableObject

public DateWritable getPrimitiveWritableObject(java.lang.Object o)

Description copied from interface: PrimitiveObjectInspector

Return the data in an instance of primitive writable Object. If the Object is already a primitive writable Object, just return o.

Specified by:

getPrimitiveWritableObject in interface DateObjectInspector

Specified by:

getPrimitiveWritableObject in interface PrimitiveObjectInspector

Overrides:

getPrimitiveWritableObject in class AbstractPrimitiveWritableObjectInspector

getPrimitiveJavaObject

public java.sql.Date getPrimitiveJavaObject(java.lang.Object o)

Description copied from interface: PrimitiveObjectInspector

Get the Java Primitive object.

Specified by:

getPrimitiveJavaObject in interface DateObjectInspector

Specified by:

getPrimitiveJavaObject in interface PrimitiveObjectInspector

copyObject

public java.lang.Object copyObject(java.lang.Object o)

Description copied from interface: PrimitiveObjectInspector

Get a copy of the Object in the same class, so the return value can be stored independently of the parameter. If the Object is a Primitive Java Object, we just return the parameter since Primitive Java Object is immutable.

Specified by:

copyObject in interface PrimitiveObjectInspector

set

public java.lang.Object set(java.lang.Object o,
                            java.sql.Date d)

Specified by:

set in interface SettableDateObjectInspector

set

public java.lang.Object set(java.lang.Object o,
                            DateWritable d)

Specified by:

set in interface SettableDateObjectInspector

create

public java.lang.Object create(java.sql.Date d)

Specified by:

create in interface SettableDateObjectInspector
