Enum StructuredPathSegmentKind

Object

Enum<StructuredPathSegmentKind>

gudusoft.gsqlparser.common.structured.StructuredPathSegmentKind

All Implemented Interfaces:

Serializable, Comparable<StructuredPathSegmentKind>

public enum StructuredPathSegmentKind
extends Enum<StructuredPathSegmentKind>

The kinds of step in a StructuredColumnPath.

SUBSCRIPT is a [expr] whose container is not known yet: the access-path normalizer (gudusoft.gsqlparser.nodes.structured.NestedAccessNormalizer) refines it to ARRAY_ELEMENT or MAP_VALUE from the declared type, the subscript syntax, or the vendor's rule, and a path that still holds one after refinement reads its base column whole. STAR is the wildcard of customer.*, always the last step.

Method Detail

values

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

Returns:

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

valueOf

public static StructuredPathSegmentKind 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
