Interface LayoutRule

All Known Implementing Classes:

AlignmentRules, AndOrConcatRules, CaseModificationRules, CaseRules, ClauseLinebreakRules, IndentRules, JoinRules, ParenAndCommaRules, SetOperatorRules, SpacingRules

public interface LayoutRule

A single layout rule. Rules read the LayoutContext (token stream + upstream analyses + decisions so far) and request layout decisions (requestLinebreaksBefore/requestBlanksBefore/requestIndent).

Rules are registered with a LayoutRulePipeline and applied in registration order. Competing writes to the same token-gap property are resolved by priority() (higher wins; later-applied wins on a tie) via the LayoutConflictResolver.

Implementations must be iterative (no recursion over deep trees) and must not mutate Pp2Token or the wrapped TSourceToken; all output goes through the context's request methods.

Plan reference: §7.3/S23, §7.4/S23.

Method Summary

Modifier and Type	Method and Description
void	apply(LayoutContext context) Apply the rule, requesting layout decisions on the context.
String	name() Short, stable identifier for logging/diagnostics.
int	priority() The rule's precedence.

Method Detail

priority

int priority()

The rule's precedence. Higher-priority rules win conflicts over lower-priority ones regardless of registration order.

name

String name()

Short, stable identifier for logging/diagnostics.

apply

void apply(LayoutContext context)

Apply the rule, requesting layout decisions on the context.
