public ColumnBuilder
getColumn()

private Set<String>
getColumnNames()

pack-priv short
getColumnNumber(String colName)

Implements abstract io.github.spannm.jackcess.impl.TableMutator.getColumnNumber.

public TableMutator.ColumnState
getColumnState(ColumnBuilder col)

Implements abstract io.github.spannm.jackcess.impl.TableMutator.getColumnState.

public IndexImpl.ForeignKeyReference
getForeignKey(IndexBuilder idx)

Overrides io.github.spannm.jackcess.impl.TableMutator.getForeignKey.

public IndexBuilder
getIndex()

public TableMutator.IndexDataState
getIndexDataState(IndexBuilder idx)

Implements abstract io.github.spannm.jackcess.impl.TableMutator.getIndexDataState.

pack-priv static Set<String>
getIndexNames(TableImpl table, boolean[] foundPk)

private short

Returns:

an id which no column of this table holds
getNextColumnId()

Access assigns each column an id which it never reuses and never renumbers, so a table which has had a column deleted has gaps in its ids and its highest id can be past the last column number.

pack-priv List<Integer>
getNextPages()

pack-priv String
getTableName()

Implements abstract io.github.spannm.jackcess.impl.TableMutator.getTableName.

public int
getTdefPageNumber()

Implements abstract io.github.spannm.jackcess.impl.TableMutator.getTdefPageNumber.

private void
initIndexDataState(byte ignoreIdxFlags, byte ignoreColFlags)

pack-priv boolean
isComplexColumn(String colName)

Implements abstract io.github.spannm.jackcess.impl.TableMutator.isComplexColumn.

Checks whether the named column holds a complex type.

pack-priv void
resetTdefInfo()

private static boolean
sameIndexData(IndexBuilder idx1, IndexData idx2, byte ignoreIdxFlags, byte ignoreColFlags)

private static boolean
sameIndexData(IndexBuilder.Column col1, IndexData.ColumnDescriptor col2, int ignoreColFlags)

pack-priv void
setForeignKey(IndexImpl.ForeignKeyReference newFkReference)

pack-priv void
setOrigTdefLen(int len)

private void

pack-priv boolean
validateUpdatedTdef(ByteBuffer tableBuffer)
