Function: javaHashAllObjects()

javaHashAllObjects(...items): Uint8Array

Java hashAllObjects for MMRData hashing Used for MMRData.CreateMMRDataLeafNode and CreateMMRDataParentNode

From Crypto.java hashAllObjects: Serializes each Streamable object and hashes the concatenation.

For MMRData, the serialization is:

  • MiniNumber: [scale][len][data] (see serializeMiniNumber)
  • MiniData: [4-byte len][data] for writeDataStream
  • Hash: [4-byte len][data] for writeHashToStream (same as MiniData)

CRITICAL: Java writeHashToStream uses writeInt (4-byte prefix), identical to writeDataStream. See MiniData.java lines 282-289.

Parameters​

items​

...Uint8Array<ArrayBufferLike>[]

Pre-serialized items to concatenate and hash

Returns​

Uint8Array

32-byte SHA3-256 hash
