Constructor Detail

FbImmutableConnectionProperties

public FbImmutableConnectionProperties(IConnectionProperties src)

Copy constructor for FbConnectionProperties.

All properties defined in IConnectionProperties are copied from src to the new instance.

Parameters:

src - Source to copy from

Method Detail

getDatabaseName

public java.lang.String getDatabaseName()

Specified by:

getDatabaseName in interface IConnectionProperties

Returns:

Name or alias of the database

setDatabaseName

public void setDatabaseName(java.lang.String databaseName)

Specified by:

setDatabaseName in interface IConnectionProperties

Parameters:

databaseName - Name or alias of the database

getAttachObjectName

public java.lang.String getAttachObjectName()

Specified by:

getAttachObjectName in interface IAttachProperties<IConnectionProperties>

Returns:

The name of the object to attach to (either a database or service name).

getConnectionDialect

public short getConnectionDialect()

Description copied from interface: IConnectionProperties

Get the dialect of the client connection

NOTE: Implementer should take care to return IConnectionProperties.DEFAULT_DIALECT if the value hasn't been set yet.

Specified by:

getConnectionDialect in interface IConnectionProperties

Returns:

SQL dialect of the client.

setConnectionDialect

public void setConnectionDialect(short connectionDialect)

Description copied from interface: IConnectionProperties

Set the dialect of the client connection

NOTE: Implementer should take care to use IConnectionProperties.DEFAULT_DIALECT if the value hasn't been set yet.

Specified by:

setConnectionDialect in interface IConnectionProperties

Parameters:

connectionDialect - SQL dialect of the client.

getPageCacheSize

public int getPageCacheSize()

Description copied from interface: IConnectionProperties

Get the page cache size.

A value of 0 indicates that the value is not set, and that the server default is used.

This option is only relevant for Firebird implementations with per connection cache (eg Classic)

NOTE: Implementer should take care to return IConnectionProperties.DEFAULT_BUFFERS_NUMBER if the value hasn't been set yet.

Specified by:

getPageCacheSize in interface IConnectionProperties

Returns:

number of cache buffers that should be allocated for this connection, should be specified for ClassicServer instances, SuperServer has a server-wide configuration parameter.

setPageCacheSize

public void setPageCacheSize(int pageCacheSize)

Description copied from interface: IConnectionProperties

Set the page cache size.

A value of 0 indicates that the value is not set, and that the server default is used.

This option is only relevant for Firebird implementations with per connection cache (eg Classic)

NOTE: Implementer should take care to use IConnectionProperties.DEFAULT_BUFFERS_NUMBER if the value hasn't been set yet.

Specified by:

setPageCacheSize in interface IConnectionProperties

Parameters:

pageCacheSize - number of cache buffers that should be allocated for this connection, should be specified for ClassicServer instances, SuperServer has a server-wide configuration parameter.

setResultSetDefaultHoldable

public void setResultSetDefaultHoldable(boolean holdable)

Description copied from interface: IConnectionProperties

Set if ResultSet should be ResultSet.HOLD_CURSORS_OVER_COMMIT by default.

Specified by:

setResultSetDefaultHoldable in interface IConnectionProperties

Parameters:

holdable - true ResultSets are holdable, false (default) ResultSets are ResultSet.CLOSE_CURSORS_AT_COMMIT

isResultSetDefaultHoldable

public boolean isResultSetDefaultHoldable()

Description copied from interface: IConnectionProperties

Get whether ResultSets are holdable by default.

Specified by:

isResultSetDefaultHoldable in interface IConnectionProperties

Returns:

true ResultSets by default are ResultSet.HOLD_CURSORS_OVER_COMMIT, false (default), ResultSets are ResultSet.CLOSE_CURSORS_AT_COMMIT

setColumnLabelForName

public void setColumnLabelForName(boolean columnLabelForName)

Description copied from interface: IConnectionProperties

Set if ResultSetMetaData.getColumnName(int) returns the columnLabel instead of the columnName.

The default behaviour (with columnLabelForName=false is JDBC-compliant. The behavior for value true is to provide compatibility with tools with a wrong expectation.

Specified by:

setColumnLabelForName in interface IConnectionProperties

Parameters:

columnLabelForName - false JDBC compliant behavior (columnName is returned), true compatibility option (columnLabel is returned)

isColumnLabelForName

public boolean isColumnLabelForName()

Description copied from interface: IConnectionProperties

Gets the current setting of columnLabelForName

Specified by:

isColumnLabelForName in interface IConnectionProperties

Returns:

false JDBC compliant behavior (columnName is returned), true compatibility option (columnLabel is returned)

See Also:

IConnectionProperties.setColumnLabelForName(boolean)

getExtraDatabaseParameters

public DatabaseParameterBuffer getExtraDatabaseParameters()

Description copied from interface: IConnectionProperties

Gets the extra database parameters. This can be used to pass extra database parameters that are not directly supported.

An immutable instance of IConnectionProperties must return a copy.

Specified by:

getExtraDatabaseParameters in interface IConnectionProperties

Returns:

DatabaseParameterBuffer instance.

asImmutable

public IConnectionProperties asImmutable()

Specified by:

asImmutable in interface IAttachProperties<IConnectionProperties>

Specified by:

asImmutable in interface IConnectionProperties

Returns:

An immutable version of this instance as an implementation of IConnectionProperties

asNewMutable

public IConnectionProperties asNewMutable()

Specified by:

asNewMutable in interface IAttachProperties<IConnectionProperties>

Specified by:

asNewMutable in interface IConnectionProperties

Returns:

A new, mutable, instance as an implementation of IConnectionProperties with all properties copied.
