Insertion of entries into the library.

The entry objects themselves are retained, not their citation keys or ids: undoing a removal and redoing it must put back the same objects, because other parts of the UI hold references to them. A move to id-based lookup would break that silently, so it would have to revisit this record.

source is reported to the model listeners. It matters because restoring entries is not the same event as adding them: entries re-inserted by an undo must not be auto-assigned to the group that happens to be selected, which the listener in LibraryTab decides by looking for EntriesEventSource#UNDO.

public ApplyResult apply()

Implements org.jabref.model.undo.BibChange.apply.

Doc from org.jabref.model.undo.BibChange.apply.

Performs this change.

Implementations hold whatever they need to act on — an entry, a string, the database — so that recording a change never requires plumbing a context to the call site.

A change that describes one value refuses when the library no longer holds that value, because a command writing on a background thread can have moved it on since, and writing over it would produce a library no step on the stack describes. A change that describes a collection or a whole subtree applies unconditionally: comparing all of it on every apply costs more than the case is worth, and a partial comparison would only look like a check.

A change describing one modification performs it or throws, and so always returns ApplyResult#SUCCESS. Only ChangeSet can apply part of what it describes, and the return value is how it says so instead of reporting a success it did not deliver.

public BibDatabase database()

Record Component getter of database.

entriesback to summary
public List<BibEntry> entries()

Record Component getter of entries.

equalsback to summary
public boolean equals(Object object)

Implements abstract java.lang.Record.equals.

Doc from java.lang.Record.equals.

Indicates whether some other object is "equal to" this one. In addition to the general contract of Object.equals, record classes must further obey the invariant that when a record instance is "copied" by passing the result of the record component accessor methods to the canonical constructor, as follows:

    R copy = new R(r.c1(), r.c2(), ..., r.cn());
then it must be the case that r.equals(copy).

@Override
hashCodeback to summary
public int hashCode()

Implements abstract java.lang.Record.hashCode.

Doc from java.lang.Record.hashCode.

Returns a hash code value for the record. Obeys the general contract of Object.hashCode. For records, hashing behavior is constrained by the refined contract of Record.equals, so that any two records created from the same components must have the same hash code.

Annotations
@Override
invertedback to summary
public UndoableRemoveEntries inverted()

Implements org.jabref.model.undo.BibChange.inverted.

Doc from org.jabref.model.undo.BibChange.inverted.

The change that reverses this one.

Must be an involution: change.inverted().inverted() equals change.

Annotations
@Override
sourceback to summary
public EntriesEventSource source()

Record Component getter of source.

toStringback to summary
public final String toString()

Implements abstract java.lang.Record.toString.

Doc from java.lang.Record.toString.

Returns a string representation of the record. In accordance with the general contract of Object#toString(), the toString method returns a string that "textually represents" this record. The result should be a concise but informative representation that is easy for a person to read.

In addition to this general contract, record classes must further participate in the invariant that any two records which are equal must produce equal strings. This invariant is necessarily relaxed in the rare case where corresponding equal component values might fail to produce equal strings for themselves.
