Package org.firebirdsql.ds

Class FBSimpleDataSource

java.lang.Object

org.firebirdsql.ds.RootCommonDataSource

org.firebirdsql.ds.AbstractConnectionPropertiesDataSource

org.firebirdsql.ds.FBSimpleDataSource

All Implemented Interfaces:

java.io.Serializable, java.sql.Wrapper, javax.naming.Referenceable, javax.sql.CommonDataSource, javax.sql.DataSource, AttachmentProperties, BaseProperties, DatabaseConnectionProperties, FirebirdConnectionProperties

public class FBSimpleDataSource
extends AbstractConnectionPropertiesDataSource
implements javax.sql.DataSource, java.io.Serializable, javax.naming.Referenceable

This is a simple implementation of DataSource interface. Connections are physically opened in DataSource.getConnection() method and physically closed in Connection.close() method.

If you need a standalone connection pool, consider using a connection pool implementation like HikariCP, c3p0 or DBCP.

Constructor Detail

FBSimpleDataSource

public FBSimpleDataSource()

Creates an instance using the default GDS type (PURE_JAVA).

FBSimpleDataSource

public FBSimpleDataSource(GDSType type)

Creates an instance using the specified GDS type.

Parameters:

type - GDS type

Method Detail

getBlobBufferLength

@Deprecated
public java.lang.Integer getBlobBufferLength()

Deprecated.

Use AbstractConnectionPropertiesDataSource.getBlobBufferSize(); will be removed in Jaybird 6

Get buffer length for the BLOB fields.

Returns:

length of BLOB buffer.

setBlobBufferLength

@Deprecated
public void setBlobBufferLength(java.lang.Integer length)

Deprecated.

Use AbstractConnectionPropertiesDataSource.setBlobBufferSize(int); will be removed in Jaybird 6

Set BLOB buffer length. This value influences the performance when working with BLOB fields.

Parameters:

length - new length of the BLOB buffer.

getTransactionParameters

public TransactionParameterBuffer getTransactionParameters(int isolation)

Description copied from interface: FirebirdConnectionProperties

Get the transaction parameter buffer corresponding to the current connection request information.

Specified by:

getTransactionParameters in interface FirebirdConnectionProperties

Parameters:

isolation - transaction isolation level for which TPB should be returned.

Returns:

instance of TransactionParameterBuffer.

setTransactionParameters

public void setTransactionParameters(int isolation,
                                     TransactionParameterBuffer tpb)

Description copied from interface: FirebirdConnectionProperties

Set transaction parameters for the specified transaction isolation level. The specified TPB is used as a default mapping for the specified isolation level.

Specified by:

setTransactionParameters in interface FirebirdConnectionProperties

Parameters:

isolation - transaction isolation level.

tpb - instance of TransactionParameterBuffer containing transaction parameters.

setNonStandardProperty

public void setNonStandardProperty(java.lang.String propertyMapping)

Description copied from interface: FirebirdConnectionProperties

Set the property that does not have corresponding setter method.

Specified by:

setNonStandardProperty in interface FirebirdConnectionProperties

Parameters:

propertyMapping - parameter value in the propertyName[=propertyValue] form, this allows setting non-standard parameters using configuration files.

getProperty

public java.lang.String getProperty(java.lang.String name)

Description copied from interface: BaseProperties

Retrieves a string property value by name.

For properties with an explicit default, this method should return the string presentation of that default, not null. For int or boolean the string equivalent is returned.

Specified by:

getProperty in interface BaseProperties

Parameters:

name - Property name (not null or empty)

Returns:

Value of the property, or null when not set or not a known property

setProperty

public void setProperty(java.lang.String name,
                        java.lang.String value)

Description copied from interface: BaseProperties

Sets a property by name.

This method can be used to set all defined properties, but also properties not known by Jaybird. When setting int or boolean properties, the appropriate conversions are applied. Using null will reset to the default value. For boolean properties, an empty string is taken to mean true.

Specified by:

setProperty in interface BaseProperties

Parameters:

name - Property name (not null or empty)

value - Property value (use null to apply default)

getIntProperty

public java.lang.Integer getIntProperty(java.lang.String name)

Description copied from interface: BaseProperties

Retrieves an int property value by name.

For properties with an explicit default, this method should return the integer presentation of that default. For implementation simplicity, it is allowed to convert any string property to int instead of checking if something is actually an int property

Specified by:

getIntProperty in interface BaseProperties

Parameters:

name - Property name (not null or empty)

Returns:

Integer with value of the property, or null when not set

setIntProperty

public void setIntProperty(java.lang.String name,
                           java.lang.Integer value)

Description copied from interface: BaseProperties

Sets an int property by name.

For implementation simplicity, it is allowed to also set string properties. The value set will be the string equivalent.

Specified by:

setIntProperty in interface BaseProperties

Parameters:

name - Property name (not null or empty)

value - Property value (use null to apply default)

getBooleanProperty

public java.lang.Boolean getBooleanProperty(java.lang.String name)

Description copied from interface: BaseProperties

Retrieves a boolean property value by name.

For properties with an explicit default, this method should return the boolean presentation of that default. For implementation simplicity, it is allowed to convert any string property to boolean instead of checking if something is actually an int property

Specified by:

getBooleanProperty in interface BaseProperties

Parameters:

name - Property name (not null or empty)

Returns:

Integer with value of the property, or null when not set

setBooleanProperty

public void setBooleanProperty(java.lang.String name,
                               java.lang.Boolean value)

Description copied from interface: BaseProperties

Sets a boolean property by name.

For implementation simplicity, it is allowed to also set string properties. The value set will be the string equivalent.

Specified by:

setBooleanProperty in interface BaseProperties

Parameters:

name - Property name (not null or empty)

value - Property value (use null to apply default)

connectionPropertyValues

public java.util.Map<ConnectionProperty,java.lang.Object> connectionPropertyValues()

Description copied from interface: BaseProperties

An unmodifiable view on the connection properties held by this BaseProperties implementation.

Be aware, implementations can have additional properties that are not mapped from ConnectionProperty. Such properties will need to be retrieved in an implementation-specific manner.

Specified by:

connectionPropertyValues in interface BaseProperties

Returns:

An unmodifiable view on the property values held in this properties instance
