Enum ColumnResolutionStatus

Object

Enum<ColumnResolutionStatus>

gudusoft.gsqlparser.ir.semantic.joinanalysis.ColumnResolutionStatus

All Implemented Interfaces:

Serializable, Comparable<ColumnResolutionStatus>

public enum ColumnResolutionStatus
extends Enum<ColumnResolutionStatus>

Outcome of resolving a ColumnRef to a base relation/final table (GAP 5).

• RESOLVED — the resolver (or a documented fallback) supplied a final-table qualified name.
• UNRESOLVED — resolution was attempted but no final table was produced (resolution==null / NOT_FOUND). The resolved name is null; a table is never fabricated.
• NOT_APPLICABLE — resolution does not apply (e.g. the column reference is itself a literal or a computed expression carried as a complex operand).

Introduced by join-analysis slice 162 (S1); populated in slice 165 (S4).

Method Detail

values

public static ColumnResolutionStatus[] 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 (ColumnResolutionStatus c : ColumnResolutionStatus.values())
    System.out.println(c);

Returns:

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

valueOf

public static ColumnResolutionStatus 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
