public abstract class VectorExpression
extends Object
implements Serializable

Base class for vector expressions.

A vector expression is a vectorized execution tree that evaluates the same result as a (row-mode) ExprNodeDesc tree describes.

A vector expression has 0, 1, or more parameters and an optional output column. These are normally passed to the vector expression object' constructor. A few special case classes accept extra parameters via set* method.

A ExprNodeColumnDesc vectorizes to the IdentityExpression class where the input column number parameter is the same as the output column number.

A ExprNodeGenericFuncDesc's generic function can vectorize to many different vectorized objects depending on the parameter expression kinds (column, constant, etc) and data types. Each vectorized class implements the getDecription which indicates the particular expression kind and data type specialization that class is designed for. The Description is used by the VectorizationContext class in matching the right vectorized class.

The constructor parameters need to be in the same order as the generic function because the VectorizationContext class automates parameter generation and object construction.

Type information is remembered for the input parameters and the output type.

A vector expression has optional children vector expressions when 1 or more parameters need to be calculated into vector scratch columns. Columns and constants do not need children expressions.

HOW TO to extend VectorExpression (some basic steps and hints): 1. Create a subclass, and write a proper getDescriptor() (column/scalar?, number for args?, etc.) 2. Define an explicit parameterless constructor 3. Define a proper parameterized constructor (according to descriptor) 4. In case of UDF, add non-vectorized UDF class to Vectorizer.supported*UDFs 5. Add the new vectorized expression class to VectorizedExpressions annotation of the original UDF 6. If you subclass an expression, do the same steps (2,3,5) for subclasses as well (ctors) 7. If your base expression class is abstract, don't add it to VectorizedExpressions annotation

childExpressions

protected VectorExpression[] childExpressions

Child expressions for parameters -- but only those that need to be computed.

NOTE: Columns and constants are not included in the children. That is: column numbers and scalar values are passed via the constructor and remembered by the individual vector expression classes. They are not represented in the children.

inputTypeInfos

protected TypeInfo[] inputTypeInfos

ALL input parameter type information is here including those for (non-computed) columns and scalar values.

The vectorExpressionParameters() method is used to get the displayable string for the parameters used by EXPLAIN, logging, etc.

inputDataTypePhysicalVariations

protected DataTypePhysicalVariation[] inputDataTypePhysicalVariations

outputColumnNum

public int outputColumnNum

Output column number and type information of the vector expression.

outputTypeInfo

protected TypeInfo outputTypeInfo

outputDataTypePhysicalVariation

protected DataTypePhysicalVariation outputDataTypePhysicalVariation

inputColumnNum

public int[] inputColumnNum

Input column numbers of the vector expression, which should be reused by vector expressions.

Constructor Detail

VectorExpression

public VectorExpression()

VectorExpression

public VectorExpression(int inputColumnNum,
                        int outputColumnNum)

Constructor for 1 input column and 1 output column.

VectorExpression

public VectorExpression(int inputColumnNum,
                        int inputColumnNum2,
                        int outputColumnNum)

Constructor for 2 input columns and 1 output column.

VectorExpression

public VectorExpression(int inputColumnNum,
                        int inputColumnNum2,
                        int inputColumnNum3,
                        int outputColumnNum)

Constructor for 3 input columns and 1 output column. Currently, VectorExpression is initialized for a maximum of 3 input columns. In case an expression with more than 3 columns wants to reuse logic here, inputColumnNum* fields should be extended.

supportsCheckedExecution

public boolean supportsCheckedExecution()

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

Returns:

true if vector expression implements a Checked variation of vector expression

toString

public String toString()

Overrides:

toString in class Object

displayUtf8Bytes

public static String displayUtf8Bytes(byte[] bytes)

displayArrayOfUtf8ByteArrays

public static String displayArrayOfUtf8ByteArrays(byte[][] arrayOfByteArrays)

shouldConvertDecimal64ToDecimal

public boolean shouldConvertDecimal64ToDecimal()

By default vector expressions do not handle decimal64 types and should be converted into Decimal types if its output cannot handle Decimal64. Decimal64 that only deal with Decimal64 types cannot handle conversions so they should override this method and return false.
