Package com.marksayson.deletionchecker.checksum

package com.marksayson.deletionchecker.checksum

CRC32C and SHA-256 helpers that hash a region of a buffer in place, without copying it. Used by com.marksayson.deletionchecker.format and com.marksayson.deletionchecker.manifest to verify dataset integrity on load and to compute checksums on write.

Related Packages

Package	Description
com.marksayson.deletionchecker	The public API: DeletionChecker, loaded once at startup from a packed dataset (com.marksayson.deletionchecker.format) and its manifest (com.marksayson.deletionchecker.manifest), then queried with isDeleted and filter for the lifetime of the instance.
com.marksayson.deletionchecker.format	The packed binary file format: one immutable, checksummed file per entity type, both read and written here.
com.marksayson.deletionchecker.manifest	The dataset manifest: a small JSON document, separate from the packed entity-type files, that records a release's format/generator/dataset versions and lists its available entity types.
