Method Detail

getObject

public java.lang.Object getObject()

Returns the primitive object represented by this LazyObject. This is useful because it can make sure we have "null" for null objects.

Specified by:

getObject in class LazyObjectBase

getWritableObject

public T getWritableObject()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

hashCode

public int hashCode()

Specified by:

hashCode in class LazyObject<OI extends ObjectInspector>

logExceptionMessage

public void logExceptionMessage(ByteArrayRef bytes,
                                int start,
                                int length,
                                java.lang.String dataType)
