Method Summary

Modifier and Type	Method and Description
java.lang.Object	copyObject(java.lang.Object o) Get a copy of the Object in the same class, so the return value can be stored independently of the parameter.
java.lang.Object	create(Text value) Create an object with the value.
java.lang.String	getPrimitiveJavaObject(java.lang.Object o) Get the String representation of the data.
Text	getPrimitiveWritableObject(java.lang.Object o) Return the data in an instance of primitive writable Object.
java.lang.Object	set(java.lang.Object o, Text value) Set the object with the value.

Method Detail

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

getPrimitiveWritableObject

public Text 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 StringObjectInspector

Specified by:

getPrimitiveWritableObject in interface PrimitiveObjectInspector

Overrides:

getPrimitiveWritableObject in class AbstractPrimitiveWritableObjectInspector

getPrimitiveJavaObject

public java.lang.String getPrimitiveJavaObject(java.lang.Object o)

Description copied from interface: StringObjectInspector

Get the String representation of the data.

Specified by:

getPrimitiveJavaObject in interface StringObjectInspector

Specified by:

getPrimitiveJavaObject in interface PrimitiveObjectInspector

create

public java.lang.Object create(Text value)

Description copied from interface: SettableStringObjectInspector

Create an object with the value.

Specified by:

create in interface SettableStringObjectInspector

set

public java.lang.Object set(java.lang.Object o,
                            Text value)

Description copied from interface: SettableStringObjectInspector

Set the object with the value. Return the object that has the new value. In most cases the returned value should be the same as o, but in case o is unmodifiable, this will return a new object with new value.

Specified by:

set in interface SettableStringObjectInspector
