Constant Field Values

Constructor Detail

InterbasePlatform

public InterbasePlatform()

Creates a new platform instance.

Method Detail

getName

public String getName()

Returns the name of the database that this platform is for.

Returns:

The name

setStatementParameterValue

protected void setStatementParameterValue(PreparedStatement statement,
                              int sqlIndex,
                              int typeCode,
                              Object value)
                                   throws SQLException

This is the core method to set the parameter of a prepared statement to a given value. The primary purpose of this method is to call the appropriate method on the statement, and to give database-specific implementations the ability to change this behavior.

Overrides:

setStatementParameterValue in class PlatformImplBase

Parameters:

statement - The statement

sqlIndex - The parameter index

typeCode - The JDBC type code

value - The value

Throws:

SQLException - If an error occurred while setting the parameter value

extractColumnValue

protected Object extractColumnValue(ResultSet resultSet,
                        String columnName,
                        int columnIdx,
                        int jdbcType)
                             throws SQLException

This is the core method to retrieve a value for a column from a result set. Its primary purpose is to call the appropriate method on the result set, and to provide an extension point where database-specific implementations can change this behavior.

Overrides:

extractColumnValue in class PlatformImplBase

Parameters:

resultSet - The result set to extract the value from

columnName - The name of the column; can be null in which case the columnIdx will be used instead

columnIdx - The index of the column's value in the result set; is only used if columnName is null

jdbcType - The jdbc type to extract

Returns:

The value

Throws:

SQLException - If an error occurred while accessing the result set

getModelComparator

protected ModelComparator getModelComparator()

Returns the model comparator to be used for this platform. This method is intendeded to be redefined by platforms that need to customize the model reader.

Overrides:

getModelComparator in class PlatformImplBase

Returns:

The model comparator

getTableDefinitionChangesPredicate

protected TableDefinitionChangesPredicate getTableDefinitionChangesPredicate()

Returns the predicate that defines which changes are supported by the platform.

Overrides:

getTableDefinitionChangesPredicate in class PlatformImplBase

Returns:

The predicate

processChange

public void processChange(Database currentModel,
                 CreationParameters params,
                 AddColumnChange change)
                   throws IOException

Processes the addition of a column to a table.

Overrides:

processChange in class PlatformImplBase

Parameters:

currentModel - The current database schema

params - The parameters used in the creation of new tables. Note that for existing tables, the parameters won't be applied

change - The change object

Throws:

IOException

processChange

public void processChange(Database currentModel,
                 CreationParameters params,
                 RemoveColumnChange change)
                   throws IOException

Processes the removal of a column from a table.

Parameters:

currentModel - The current database schema

params - The parameters used in the creation of new tables. Note that for existing tables, the parameters won't be applied

change - The change object

Throws:

IOException
