Constructor Detail DatabaseSchema public DatabaseSchema(String vdbName)(Code) Creates a new DatabaseSchema instance. Parameters:   vdbName - the virtual database name this schema represents DatabaseSchema public DatabaseSchema(String vdbName, int nbOfTables)(Code) Creates a new DatabaseSchema instance with a specified number of tables. Parameters:   vdbName - the virtual database name this schema represents Parameters:   nbOfTables - an int value DatabaseSchema public DatabaseSchema(DatabaseSchema schema)(Code) Creates a new DatabaseSchema instance from an existing database schema (the schema is cloned). Parameters:   schema - the existing database schema Method Detail addProcedure public synchronized void addProcedure(DatabaseProcedure procedure)(Code) Adds a DatabaseProcedure describing a procedure of the database. Parameters:   procedure - the procedure to add addTable public synchronized void addTable(DatabaseTable table)(Code) Adds a DatabaseTable describing a table of the database. Parameters:   table - the table to add allTablesAreUnlockedOrLockedByTransaction public boolean allTablesAreUnlockedOrLockedByTransaction(AbstractRequest request)(Code) Returns true if all tables are not locked by anyone. Parameters:   request - request trying to execute (to indicate if it is inautocommit mode and the transaction id) true if all tables are unlocked. equals public boolean equals(Object other)(Code) Two DatabaseSchema are considered equal if they have the same tables and the same procedures. Parameters:   other - the object to compare with true if the schemas are equals getLock public TransactionLogicalLock getLock()(Code) Returns the lock for this table. a TransactionLogicalLock instance getProcedure public DatabaseProcedure getProcedure(String procedureKey)(Code) Returns the DatabaseProcedure object matching the given procedure name or null if not found. Parameters:   procedureKey - the procedure key to look for a DatabaseProcedure value or null getProcedure public DatabaseProcedure getProcedure(DatabaseProcedure procedure)(Code) Returns the DatabaseProcedure object matching the given procedure or null if not found. Parameters:   procedure - the procedure to look for a DatabaseProcedure value or null getProcedures public HashMap getProcedures()(Code) Returns an HashMap of DatabaseProcedure objects describing the database. The key entry is given by DatabaseProcedure.getKey(). an HashMap of DatabaseProcedure getTable public DatabaseTable getTable(String tableName)(Code) Returns the DatabaseTable object matching the given table name or null if not found. Parameters:   tableName - the table name to look for a DatabaseTable value or null getTable public DatabaseTable getTable(String tableName, boolean isCaseSensitive)(Code) Returns the DatabaseTable object matching the given table name or null if not found. An extra boolean indicates if table name matching is case sensitive or not. Parameters:   tableName - the table name to look for Parameters:   isCaseSensitive - true if name matching must be case sensitive a DatabaseTable value or null getTables public synchronized HashMap getTables()(Code) Returns an HashMap of DatabaseTable objects describing the database. The key is the table name. an HashMap of DatabaseTable getVirtualDatabaseName final public String getVirtualDatabaseName()(Code) Returns the virtual database name value. Returns the virtual database name. getXml public String getXml()(Code) Get xml information about this schema. xml formatted information on this database schema. hasATableLockedByTransaction public boolean hasATableLockedByTransaction(long transactionId)(Code) Returns true if the given transaction locks (or wait for a lock) on any of the table of this schema. Parameters:   transactionId - the transaction identifier true if the transaction locks or wait for a lock on at least onetable hasProcedure public boolean hasProcedure(String procedureName, int nbOfParameters)(Code) Returns true if the given ProcedureName is found in this schema. Parameters:   procedureName - the name of the procedure you are looking for Parameters:   nbOfParameters - number of parameters of the stored procecdure true if the procedure has been found hasTable public boolean hasTable(String tableName)(Code) Returns true if the given TableName is found in this schema. Parameters:   tableName - the name of the table you are looking for true if the table has been found isCompatibleSubset public boolean isCompatibleSubset(DatabaseSchema other)(Code) Checks if this DatabaseSchema is a compatible subset of a given schema. It means that all tables in this schema must be present with the same definition in the other schema. Parameters:   other - the object to compare with true if the two schemas are compatible isCompatibleWith public boolean isCompatibleWith(DatabaseSchema other)(Code) Checks if this DatabaseSchema is compatible with the given schema. It means that all tables in this schema that are common with the other schema must be identical.

Parameters:   request - request trying to execute (to indicate if it is inautocommit mode and the transaction id) list of locks acquired (excluding locks already acquired beforethis method was called) mergeSchema public void mergeSchema(DatabaseSchema databaseSchema) throws SQLException(Code) Merges the given schema with the current one. All missing tables or columns are added if no conflict is detected. An exception is thrown if the given schema definition conflicts with the current one. Parameters:   databaseSchema - the schema to merge throws:   SQLException - if the schemas conflict releaseLocksOnAllTables public void releaseLocksOnAllTables(long transactionId)(Code) Release locks held by the given transaction on all tables. Parameters:   transactionId - the transaction identifier removeProcedure public synchronized boolean removeProcedure(DatabaseProcedure procedure)(Code) removes a DatabaseProcedure describing a procedure of the database. Parameters:   procedure - to remove true if the procedure was successfully removed removeTable public synchronized boolean removeTable(DatabaseTable table)(Code) Removes a DatabaseTable describing a table of the database. Parameters:   table - the table to remove true if the table was successfully removed removeTableFromDependingTables public synchronized void removeTableFromDependingTables(DatabaseTable table)(Code) Removes a DatabaseTable from the depending tables list of all tables in the schema. Parameters:   table - the table to remove setLocks public void setLocks(DatabaseSchema oldSchema)(Code) When the database schema is reloaded, the locks held by active transactions must be retained. Parameters:   oldSchema - the previous version of the schema. updateSchema public void updateSchema(DatabaseSchema databaseSchema)(Code) Updates the given schema with the current one. All missing tables or columns are added and if the given schema definition conflicts with the current one, the current schema definition is overriden with the one that is provided.
