Class Row

java.lang.Object

org.nuxeo.ecm.core.storage.sql.RowId

org.nuxeo.ecm.core.storage.sql.Row

All Implemented Interfaces:

Serializable, Cloneable, Comparable<RowId>

public final class Row
extends RowId
implements Serializable, Cloneable

The data of a single row in a table (keys/values form a map), or of multiple rows with the same id (values is an array of Serializable).

The id of the row is distinguished internally from other columns. For fragments corresponding to created data, the initial id is a temporary one, and it will be changed after database insert.

Field Detail

OPAQUE

public static final Serializable OPAQUE

A database value we don't care about reading. When present in a fragment, it won't be written, but any other value will be.

keys

protected String[] keys

The row keys, for single row.

values

public Serializable[] values

The row values.

size

protected int size

The size of the allocated part of values, for single rows.

MAX_STRING

public static final int MAX_STRING

Constructor Detail

Row

public Row(String tableName,
           Serializable id)

Constructs an empty Row for the given table with the given id (may be null).

Row

public Row(String tableName,
           Map<String,Serializable> map)

Constructs a new Row from a map.

Parameters:

map - the initial data to use

Row

public Row(String tableName,
           Serializable id,
           Serializable[] array)

Constructs a new Row from an array of values.

Parameters:

array - the initial data to use

Method Detail

clone

public Row clone()

Overrides:

clone in class Object

isCollection

public boolean isCollection()

put

public void put(String key,
                Serializable value)

Puts a key/value. Does not deal with deltas.

Parameters:

key - the key

value - the value

put

public void put(String key,
                Serializable value,
                Serializable[] oldvalues)

Puts a key/value where the current or new value may be a delta. To resolve a delta, the oldvalues (in-database state) must be consulted.

Parameters:

key - the key

value - the value

oldvalues - the old values

putNew

public void putNew(String key,
                   Serializable value)

Puts a key/value, assuming the key is not already there.

Parameters:

key - the key

value - the value

get

public Serializable get(String key)

Gets a value from a key.

Parameters:

key - the key

Returns:

the value

getKeys

public List<String> getKeys()

Gets the list of keys. The id is not included.

getValues

public List<Serializable> getValues()

Gets the list of values. The id is not included.

toString

public String toString()

Overrides:

toString in class RowId

printValue

public static void printValue(Serializable value,
                              StringBuilder sb)
