Field Detail

factory

public static final ISortedColumns.Factory factory
Method Detail

factory

public static ISortedColumns.Factory factory()

getComparator

public AbstractType<?> getComparator()
Specified by:
getComparator in interface IIterableColumns

getFactory

public ISortedColumns.Factory getFactory()
Description copied from interface: ISortedColumns
Returns the factory used for this ISortedColumns implementation.

Specified by:
getFactory in interface ISortedColumns

cloneMe

public ISortedColumns cloneMe()
Description copied from interface: ISortedColumns
Shallow cloning of the column map.

Specified by:
cloneMe in interface ISortedColumns

isInsertReversed

public boolean isInsertReversed()
Description copied from interface: ISortedColumns
Returns if this map only support inserts in reverse order.

Specified by:
isInsertReversed in interface ISortedColumns

addColumn

public void addColumn(IColumn column,
                      Allocator allocator)
Description copied from interface: ISortedColumns
Adds a column to this column map. If a column with the same name is already present in the map, it will be replaced by the newly added column.

Specified by:
addColumn in interface ISortedColumns

addAllColumns

protected void addAllColumns(ISortedColumns cm,
                             Allocator allocator,
                             com.google.common.base.Function<IColumn,IColumn> transformation)
We need to go through each column in the column container and resolve it before adding

Specified by:
addAllColumns in class AbstractThreadUnsafeSortedColumns

replace

public boolean replace(IColumn oldColumn,
                       IColumn newColumn)
Description copied from interface: ISortedColumns
Replace oldColumn if present by newColumn. Returns true if oldColumn was present and thus replaced. oldColumn and newColumn should have the same name.

Specified by:
replace in interface ISortedColumns

getColumn

public IColumn getColumn(java.nio.ByteBuffer name)
Description copied from interface: ISortedColumns
Get a column given its name, returning null if the column is not present.

Specified by:
getColumn in interface ISortedColumns

removeColumn

public void removeColumn(java.nio.ByteBuffer name)
Description copied from interface: ISortedColumns
Remove if present a column by name.

Specified by:
removeColumn in interface ISortedColumns

clear

public void clear()
Description copied from interface: ISortedColumns
Clear this column map, removing all columns.

Specified by:
clear in interface ISortedColumns

size

public int size()
Description copied from interface: ISortedColumns
Returns the number of columns in this map.

Specified by:
size in interface ISortedColumns

getSortedColumns

public java.util.Collection<IColumn> getSortedColumns()
Description copied from interface: ISortedColumns
Returns the columns of this column map as a collection. The columns in the returned collection should be sorted as the columns in this map.

getReverseSortedColumns in interface ISortedColumns

getColumnNames

public java.util.SortedSet<java.nio.ByteBuffer> getColumnNames()
Description copied from interface: ISortedColumns
Returns a set with the names of columns in this column map. The resulting set is sorted and the order is the one of the columns in this column map.

Specified by:
getColumnNames in interface ISortedColumns

Specified by:
iterator in interface java.lang.Iterable<IColumn>

reverseIterator

public java.util.Iterator<IColumn> reverseIterator()
Description copied from interface: ISortedColumns
Returns an iterator that iterates over the columns of this map in reverse order.

Specified by:
reverseIterator in interface ISortedColumns

iterator

Description copied from interface: ISortedColumns
Returns an iterator over the columns of this map starting from the first column whose name is equal or greater than @param start.

Specified by:
iterator in interface ISortedColumns

reverseIterator

public java.util.Iterator<IColumn> reverseIterator(java.nio.ByteBuffer start)
Description copied from interface: ISortedColumns
Returns a reversed iterator over the columns of this map starting from the last column whose name is equal or lesser than @param start.

Specified by:
reverseIterator in interface ISortedColumns
