Method: ContentData::ContentData#to_file_old

Defined in:
lib/content_data/content_data.rb

#to_file_old(filename) ⇒ Object

Deprecated.

DEPRECATED: Old deprecated from/to file methods still needed for migration purposes Write content data to file. Write is using chunks (for both content chunks and instances chunks) Chunk is used to maximize GC affect. The temporary memory of each chunk is GCed. Without the chunks used in a dipper stack level, GC keeps the temporary objects as part of the stack context.
