IpcLimits class final
Resource limits applied while decoding untrusted IPC input.
Defaults are conservative; trusted callers handling larger data should pass raised limits explicitly.
Constructors
- IpcLimits({int maxDepth = 64, int maxFields = 10000, int maxRows = 1 << 20, int maxValues = 4 << 20, int maxBuffers = 1 << 16, int maxMessageBytes = 64 << 20, int maxDictionaries = 1024, int maxBatches = 1 << 20})
-
Creates limits; every bound is inclusive.

Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- maxBatches → int
-
Maximum number of record batches.
final
- maxBuffers → int
-
Maximum number of field nodes or buffers in one message.
final
- maxDepth → int
-
Maximum type nesting depth.
final
- maxDictionaries → int
-
Maximum number of dictionary batches.
final
- maxFields → int
-
Maximum number of fields (including nested children) in a schema.
final
- maxMessageBytes → int
-
Maximum size of a message's metadata, body, decompressed body or file
footer.
final
- maxRows → int
-
Maximum length of any single array node (and of a delta-merged
dictionary).
final
- maxValues → int
-
Maximum total of all field node lengths decoded by one reader. Bounds
work even for layouts (such as Null or run-end encoded) whose wire size
is independent of their logical length.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
