DatabaseTable
public class DatabaseTable implements Serializable(Code)
	A `DatabaseTable` represents a database table ! It is just an array of `TableColumns` objects. Keep it mind that `ArrayList` is not synchronized... author: Emmanuel Cecchet author: Mathieu Peltier author: Sara Bouchenak version: 1.0

Constructor Summary
public	DatabaseTable(String name) Creates a new `DatabaseTable` instance.
public	DatabaseTable(String name, int nbOfColumns) Creates a new `DatabaseTable` instance.
public	DatabaseTable(DatabaseTable dt) Creates a new `DatabaseTable` instance.

Method Summary
public void	addColumn(DatabaseColumn column) Adds a `DatabaseColumn` object to this table.
public synchronized void	addDependingTable(String tableName) Add a depending table to this table.
public boolean	equals(Object other) Two `DatabaseTable` are considered equal if they have the same name and the same columns.
public boolean	equalsIgnoreType(Object other) This function is the same as equals but ignores the column type.
public DatabaseColumn	getColumn(String columnName) Returns the `DatabaseColumn` object matching the given column name or `null` if not found (the case is ignored).
public DatabaseColumn	getColumn(String columnName, boolean isCaseSensitive) Returns the `DatabaseColumn` object matching the given column name or `null` if not found (the case can be enforced).
public ArrayList	getColumns() Returns a list of `DatabaseColumn` objects describing the columns of this table.
public ArrayList	getDependingTables() Returns the dependingTables value.
public TransactionLogicalLock	getLock() Returns the lock for this table.
public String	getName() Gets the name of the table.
public String	getSchema() Returns the schema value.
public ArrayList	getUniqueColumns() Returns a list of `DatabaseColumn` objects representing the unique columns of this table.
public String	getXml() Get xml information about this table.
public void	merge(DatabaseTable table) Merges this table with the given table.
public void	removeColumn(String columnName) Drops a `DatabaseColumn` object from this table.
public void	removeColumn(DatabaseColumn column) Drops a `DatabaseColumn` object from this table.
void	setLock(DatabaseTable oldTable) Retain locks held by a transaction when the schema is reloaded.
public void	setSchema(String schema) Sets the schema value.
public String	toString()
public void	updateColumns(DatabaseTable table) Updates this table with the given table's columns.

Constructor Detail

DatabaseTable
public DatabaseTable(String name)(Code)
	Creates a new `DatabaseTable` instance. Parameters: name - table name

DatabaseTable
public DatabaseTable(String name, int nbOfColumns)(Code)
	Creates a new `DatabaseTable` instance. Parameters: name - table name Parameters: nbOfColumns - number of columns

DatabaseTable
public DatabaseTable(DatabaseTable dt)(Code)
	Creates a new `DatabaseTable` instance. New table shares (only) its name and columns with the table passed as parameter. Parameters: dt - database table

Method Detail

addColumn
public void addColumn(DatabaseColumn column)(Code)
	Adds a `DatabaseColumn` object to this table. Warning! The underlying `ArrayList` is not synchronized. Parameters: column - a `DatabaseColumn` value

addDependingTable
public synchronized void addDependingTable(String tableName)(Code)
	Add a depending table to this table. A depending table is locked when the current table is updated. A depending table is usually a table that has a foreign key referencing the current table. This method takes care of duplicates and a table name is only inserted once. Parameters: tableName - the depending table to add

equals
public boolean equals(Object other)(Code)
	Two `DatabaseTable` are considered equal if they have the same name and the same columns. Parameters: other - the object to compare with `true` if the tables are equal

equalsIgnoreType
public boolean equalsIgnoreType(Object other)(Code)
	This function is the same as equals but ignores the column type. Parameters: other - the object to compare with `true` if the table are equal ignoring the columnstype See Also: DatabaseTable.equals(Object)

getColumn
public DatabaseColumn getColumn(String columnName)(Code)
	Returns the `DatabaseColumn` object matching the given column name or `null` if not found (the case is ignored). Parameters: columnName - column name to look for a `DatabaseColumn` value or `null`

getColumn
public DatabaseColumn getColumn(String columnName, boolean isCaseSensitive)(Code)
	Returns the `DatabaseColumn` object matching the given column name or `null` if not found (the case can be enforced). Parameters: columnName - column name to look for Parameters: isCaseSensitive - true if name matching must be case sensitive a `DatabaseColumn` value or `null`

getColumns
public ArrayList getColumns()(Code)
	Returns a list of `DatabaseColumn` objects describing the columns of this table. Warning! The underlying `ArrayList` is not synchronized. an `ArrayList` of `DatabaseColumn`

getDependingTables
public ArrayList getDependingTables()(Code)
	Returns the dependingTables value. Returns the dependingTables.

getLock
public TransactionLogicalLock getLock()(Code)
	Returns the lock for this table. a `TransactionLogicalLock` instance

getName
public String getName()(Code)
	Gets the name of the table. the table name

getSchema
public String getSchema()(Code)
	Returns the schema value. Returns the schema.

getUniqueColumns
public ArrayList getUniqueColumns()(Code)
	Returns a list of `DatabaseColumn` objects representing the unique columns of this table. Warning! The underlying `ArrayList` is not synchronized. an `ArrayList` of `DatabaseColumn`objects

getXml
public String getXml()(Code)
	Get xml information about this table. xml formatted information on this database table.

merge
public void merge(DatabaseTable table) throws SQLException(Code)
	Merges this table with the given table. Both columns and depending tables are merged. All missing columns are added if no conflict is detected. An exception is thrown if the given table columns conflicts with this one. Parameters: table - the table to merge throws: SQLException - if the schemas conflict

removeColumn
public void removeColumn(String columnName)(Code)
	Drops a `DatabaseColumn` object from this table. Warning! The underlying `ArrayList` is not synchronized. Parameters: columnName - a `String` that maps to a`DatabaseColumn` value

removeColumn
public void removeColumn(DatabaseColumn column)(Code)
	Drops a `DatabaseColumn` object from this table. Warning! The underlying `ArrayList` is not synchronized. Parameters: column - a `DatabaseColumn` value

setLock
void setLock(DatabaseTable oldTable)(Code)
	Retain locks held by a transaction when the schema is reloaded. Parameters: oldTable - the previous version of this table

setSchema
public void setSchema(String schema)(Code)
	Sets the schema value. Parameters: schema - The schema to set.

toString
public String toString()(Code)
	See Also: java.lang.Object.toString

updateColumns
public void updateColumns(DatabaseTable table)(Code)
	Updates this table with the given table's columns. All missing columns are added and if the given table columns conflicts with this one, the current column definition is overriden with the provided one. Note that existing locks (if any) are preserved. Warning! Data structures of the given table are not cloned. Parameters: table - the table to use to update the current one
