Method Detail

evaluate

public void evaluate(VectorizedRowBatch batch)
              throws HiveException

Description copied from class: VectorExpression

This is the primary method to implement expression logic.

Specified by:

evaluate in class VectorExpression

Throws:

HiveException

supportsCheckedExecution

public boolean supportsCheckedExecution()

Description copied from class: VectorExpression

A vector expression which implements a checked execution to account for overflow handling should override this method and return true. In such a case Vectorizer will use Checked variation of the vector expression to process data

Overrides:

supportsCheckedExecution in class VectorExpression

Returns:

true if vector expression implements a Checked variation of vector expression

vectorExpressionParameters

getDescriptor

public VectorExpressionDescriptor.Descriptor getDescriptor()

Specified by:
