Detailed Description

A simple object that the Ledger uses to store entries.

NodeObjects are comprised of a type, a hash, and a blob. They can be uniquely identified by the hash, which is a half-SHA512 of the blob. The blob is a variable length block of serialized data. The type identifies what the blob contains.

Note

No checking is performed to make sure the hash matches the data.

Member Function Documentation

createObject()

std::shared_ptr< NodeObject > ripple::NodeObject::createObject ( NodeObjectType  type, Blob &&  data, uint256 const &  hash  )

static

Create an object from fields.

The caller's variable is modified during this call. The underlying storage for the Blob is taken over by the NodeObject.

Parameters

type	The type of object.
ledgerIndex	The ledger in which this object appears.
data	A buffer containing the payload. The caller's variable is overwritten.
hash	The 256-bit hash of the payload data.
