Functions

clear

abstract fun clear()

Delete all items

clearDecrypter

abstract fun clearDecrypter()

If you want to use the same database sequentially with multiple wallets, then you can clear the decrypter. This is really meant for efficient tests not production use.

abstract fun close()

close this database, releasing any resources

delete

abstract fun delete(vararg idems: ByteArray)

open fun delete(vararg idems: Hash256)

forEach

abstract fun forEach(doit: (TransactionHistory) -> Boolean, startingDate: Long = Long.MAX_VALUE, count: Long = Long.MAX_VALUE)

Iterates from newest to oldest

forEachForwards

abstract fun forEachForwards(doit: (TransactionHistory) -> Boolean, startingDate: Long = Long.MAX_VALUE, count: Long = Long.MAX_VALUE)

Iterates from oldest to newest

forEachWithAddress

abstract fun forEachWithAddress(addr: PayAddress, doit: (TransactionHistory) -> Boolean)

Wallet history iterator, of a particular address.

installDecrypter

abstract fun installDecrypter(decrypt: (ByteArray, Int) -> ByteArray)

Provide a decryption function to associate with any SecuredSecrets stored in this database. The decryption function will not be called until the secret is actually needed.

read

abstract fun read(idem: Hash256): TransactionHistory?

Read one item

readAll

abstract fun readAll(): MutableMap<Hash256, TransactionHistory>

Read all items and return a map of each entry

size

abstract fun size(): Long

write

abstract fun write(vararg txh: TransactionHistory?)

writeAll

abstract fun writeAll(fullmap: MutableMap<Hash256, TransactionHistory>)

Insert or overwrite all items in the provided map into the database

writeDirty

abstract fun writeDirty(fullmap: MutableMap<Hash256, TransactionHistory>): Int

Insert or overwrite all changed items in the provided map into the database
