Class AcDbDxfFiler

True if the next pair starts a new object (group code 0) or EOF. Does not consume the pair.

True if no more pairs are available.

True if the next pair is XDATA start (1001) or similar extended data.

DXF dialect capabilities for the target write version. When version is unset (ad-hoc writers / unit tests), treat as latest.

Advance past subclass marker (100, name) if present. Returns true when positioned at the named subclass data.

Peek the next pair without consuming it.

Current read position in the underlying pair stream. Useful for byte-based parse progress while streaming a DXF.

Push the last-read (or provided) pair back so the next read returns it. Multiple pushbacks form a LIFO stack (nested readers can push without overwriting a prior push).

Apply color group codes (62 ACI / 420 true color) onto color when the current pair matches. Returns true if a color code was consumed.

Read one DXF item into a typed value (ObjectARX readItem). Returns undefined at EOF and sets filerStatus to EndOfFile.

Read a 2D point starting at code (x), then code+10 (y). Tolerates missing Y (defaults to 0) when the next code is not code+10.

Read a 3D point starting at code (x), then code+10 / code+20. Missing Y/Z default to 0 when those group codes are absent.

Skip pairs until the next object boundary (code 0) without consuming it.

Finalize binary DXF bytes (includes magic prefix).

Lineweight (group 370). Omitted for DXF targets before AutoCAD 2000.

Write MTEXT (or embedded-MTEXT) contents using AutoCAD's group 3 / group 1 250-character chunking rules.

Create a read-mode filer from an existing pair reader.

Create a read-mode filer from DXF bytes (ASCII or binary).

Create a read-mode filer from an already-decoded ASCII DXF string.
