Method Detail

dbms

public boolean dbms(java.lang.String dbms)

Description copied from interface: BeanFactory

Determines whether a BeanFactory implementation can generate beans for the given dbms. Returns true if this is a valid dbms name for this service provider, false otherwise.

Parameters:

dbms - the name of the dbms for a service provider, e.g. "mysql"

Returns:

true if this service provider can generate beans for the given dbms

acquireDatasourceConnection

public void acquireDatasourceConnection(java.util.Map<java.lang.String,java.lang.String> connectionDetails)
                                 throws BeanGenerationException

Description copied from interface: BeanFactory

Acquire a connection to the underlying datasource. This map should contain parameters for databse URL, username, and password. Use getDatasourceConnectionParameters().keySet() to get the parameters that must be set. Or do a lookup on these key values to get the default values (e.g. "anonymous" is the default username). This way, those parameters which have been set can be used, whilst null fields will be ignored if possible (for example, in the case where password="" in accessing a public MySql database).

Parameters:

connectionDetails - a map containing parameters for connection to the database.

Throws:

BeanGenerationException - if the connection could not be acquired

terminateDatasourceConnection

public void terminateDatasourceConnection()
                                   throws BeanGenerationException

Description copied from interface: BeanFactory

Close the connection to the underlying datasource. Any open connection will be closed, and it is very important that implementations of this class close all connections correclty to prevent future access problems.

Throws:

BeanGenerationException - if there is a problem closing the connection

getQueryGeneratorClass

protected java.lang.Class getQueryGeneratorClass()

Description copied from class: SQLBeanFactory

Return the class that concrete BeanFactory implementations use to the create a query.

Specified by:

getQueryGeneratorClass in class SQLBeanFactory

Returns:

the corresponding QueryGeneratorClass for BeanFactory concrete implementations

getJavaType

protected java.lang.String getJavaType(java.lang.String sqlType)
                                throws BeanGenerationException

Get the Java Type that matches the given postgres SQL type

Specified by:

getJavaType in class SQLBeanFactory

Parameters:

sqlType - the type to match

Returns:

the corresponding java type

Throws:

BeanGenerationException - if the type submitted could not be matched
