public class RecordIndexUniquenessViolation
extends RecordCoreException

An exception thrown when there is an attempt to store a duplicate value in a unique index.

Method Detail

getIndex

@Nonnull
public Index getIndex()

Get the index associated with this uniqueness violation.

Returns:

the index associated with this uniqueness violation

getIndexEntry

@Nullable
public IndexEntry getIndexEntry()

Get the index value of this uniqueness violation. This is the value the index took for some record that conflicted with the value for a different record.

Returns:

the index key of this uniqueness violation

getPrimaryKey

@Nullable
public Tuple getPrimaryKey()

Get the primary key of this uniqueness violation. This is the record that was added that triggered the uniqueness violation

Returns:

the primary key of this uniqueness violation

getExistingKey

@Nullable
public Tuple getExistingKey()

Get the existing key of this uniqueness violation. This is the primary key of the record that was already within the database at the time the second record was added.

Returns:

the existing key of this uniqueness violation
