Detailed Description

This special kind of record marks the top node of an instance subtree.

This subtree lives outside of the normal hierarchy, and is MultiGen's way of supporting instancing--each instance subtree has a unique index, which may be referenced in a FltInstanceRef object to make the instance appear in various places in the hierarchy.

Member Function Documentation

bool FltInstanceDefinition::build_record ( FltRecordWriter writer) const [protected, virtual]

Fills up the current record on the FltRecordWriter with data for this record, but does not advance the writer.

Returns true on success, false if there is some error.

Reimplemented from FltBead.

Definition at line 64 of file fltInstanceDefinition.cxx.

bool FltInstanceDefinition::extract_record ( FltRecordReader reader) [protected, virtual]

Fills in the information in this bead based on the information given in the indicated datagram, whose opcode has already been read.

Returns true on success, false if the datagram is invalid.

Reimplemented from FltBead.

static void FltInstanceDefinition::init_type ( ) [inline, static]

This function is declared non-inline to work around a compiler bug in g++ 2.96.

Making it inline seems to cause problems in the optimizer.

Reimplemented from FltBead.
