Method Detail

copyObject

public Object copyObject(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 org.apache.hadoop.io.Text getPrimitiveWritableObject(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 AbstractPrimitiveLazyObjectInspector<org.apache.hadoop.io.Text>

getPrimitiveJavaObject

public String getPrimitiveJavaObject(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

isEscaped

public boolean isEscaped()

getEscapeChar

public byte getEscapeChar()
