Class LayoutConflictResolver

Object

gudusoft.gsqlparser.pp2.layout.LayoutConflictResolver

public final class LayoutConflictResolver
extends Object

Decides which of two competing layout writes to the same token-gap property wins, by priority.

Precedence (deterministic)

1. A write with a strictly higher LayoutRule.priority() always wins over a lower-priority write, regardless of registration order.
2. On equal priority, the later-applied write wins. Because LayoutRulePipeline applies rules in registration order, this means a later-registered rule of equal priority overrides an earlier one. This is implemented as accept = incoming >= current.

The resolver is stateless; LayoutContext keeps the per-property winning priority and consults this resolver on each requested write.

Plan reference: §7.3/S23, §7.4/S23.
