Method Detail

unsafeReadRecordsInto

Notes:

• This implementation does not guarantee to return valid results if the journal is in use. The caller is responsible to control this state.
• The journal is read from the beginning to end with the oldest entry being first. If only a subset of data is required, the given collection should take care to capture the required data.

Parameters:

target - the target collection to read the records into.

includeInvalid - specified whether broken records are attempted to be included.

Throws:

IOException - In case of reading the first record fails.
