Enum DivergenceClass

Object

Enum<DivergenceClass>

gudusoft.gsqlparser.ir.semantic.diff.DivergenceClass

All Implemented Interfaces:

Serializable, Comparable<DivergenceClass>

public enum DivergenceClass
extends Enum<DivergenceClass>

Slice-7 divergence classes; the in-scope subset of the seven classes defined in the unified-roadmap §10.4.

Enum Constant Summary

Enum Constants

Enum Constant and Description
AGGREGATION_MISMATCH Both sides know the output but disagree about its aggregate flag.
BINDING_MISMATCH Same (role, output, baseColumn) but different baseTable.
FILTER_OR_JOIN_SCOPE_MISMATCH Same (output, baseTable, baseColumn) but role differs (FILTER vs JOIN).
IR_EXTRA_DEPENDENCY IR projection has the edge or output, dlineage projection does not.
IR_MISSING_DEPENDENCY Dlineage projection has the edge or output, IR projection does not.
UNSUPPORTED_BY_DLINEAGE Dlineage projection bailed — whole comparison flagged once.
UNSUPPORTED_BY_IR Builder threw — whole comparison flagged once.

Enum Constant Detail

IR_MISSING_DEPENDENCY

public static final DivergenceClass IR_MISSING_DEPENDENCY

Dlineage projection has the edge or output, IR projection does not.

IR_EXTRA_DEPENDENCY

public static final DivergenceClass IR_EXTRA_DEPENDENCY

IR projection has the edge or output, dlineage projection does not.

BINDING_MISMATCH

public static final DivergenceClass BINDING_MISMATCH

Same (role, output, baseColumn) but different baseTable.

FILTER_OR_JOIN_SCOPE_MISMATCH

public static final DivergenceClass FILTER_OR_JOIN_SCOPE_MISMATCH

Same (output, baseTable, baseColumn) but role differs (FILTER vs JOIN).

AGGREGATION_MISMATCH

public static final DivergenceClass AGGREGATION_MISMATCH

Both sides know the output but disagree about its aggregate flag.

UNSUPPORTED_BY_IR

public static final DivergenceClass UNSUPPORTED_BY_IR

Builder threw — whole comparison flagged once.

UNSUPPORTED_BY_DLINEAGE

public static final DivergenceClass UNSUPPORTED_BY_DLINEAGE

Method Detail

values

public static DivergenceClass[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (DivergenceClass c : DivergenceClass.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DivergenceClass valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
