Enum RendererId

Enum<RendererId>

gudusoft.gsqlparser.pp2.RendererId

All Implemented Interfaces:

Serializable, Comparable<RendererId>

public enum RendererId
extends Enum<RendererId>

Identifies which strategy produced a given output region — in practice, whether pp formatted that part of the input or pp2 had to.

Created here in S3 (not S16) because Pp2FormatResult.Region carries one; S16 simply populates the dispatch values.

• GUARDED_AST — pp formatted this region. The text is FormatterFactory.pp()'s own output, taken unchanged after it passed the TokenEquivalence guard. Reached either by the whole-document fast path or, per region, via GuardedAstDelegate (S13). Any region the input parses cleanly in should land here.
• LEXICAL_ISLAND — pp could not be used here (the region did not parse, pp threw, or pp's output failed the guard), so LexicalIslandRenderer (S31) laid it out from the token stream alone. Layout is plainer than pp's, but no token is lost.
• CONSERVATIVE — last resort: ConservativeTokenRenderer (S14), a single-space token passthrough. Used when the island renderer also declined.
• AST_OVERLAY — AstOverlayRenderer (v3, not in v2). The enum value exists so v3 can light it up without an API change.

A result whose regions are all GUARDED_AST is pp output end to end; the other values pinpoint the byte ranges pp could not reach.

Method Detail

values

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

Returns:

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

valueOf

public static RendererId 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
