class SourceLocationSequence

Declaration

class SourceLocationSequence { /* full declaration omitted */ };

Description

Serialized encoding of a sequence of SourceLocations. Optimized to produce small values when locations with the sequence are similar. Each element can be delta-encoded against the last nonzero element. Sequences should be started by creating a SourceLocationSequence::State, and then passed around as SourceLocationSequence*. Example: // establishes a sequence void EmitTopLevelThing() { SourceLocationSequence::State Seq; EmitContainedThing(Seq); EmitRecursiveThing(Seq); } // optionally part of a sequence void EmitContainedThing(SourceLocationSequence *Seq = nullptr) { Record.push_back(SourceLocationEncoding::encode(SomeLoc, Seq)); } // establishes a sequence if there isn't one already void EmitRecursiveThing(SourceLocationSequence *ParentSeq = nullptr) { SourceLocationSequence::State Seq(ParentSeq); Record.push_back(SourceLocationEncoding::encode(SomeLoc, Seq)); EmitRecursiveThing(Seq); }
