createDataSource
public DataSource createDataSource(Map<String,?> params) throws IOException
Description copied from interface:DataSourceFactorySpi
Construct a live data source using the params specifed. The returned DataSource may be pooled.- Parameters:
params
- The full set of information needed to construct a live DataSource.- Returns:
- The created DataSource, this may be null if the required resource was not found or if insufficent parameters were given. Note that canProcess() should have returned false if the problem is to do with insuficent parameters.
- Throws:
IOException
- if there were any problems setting up (creating or connecting) the datasource.
-
canProcess
public boolean canProcess(Map<String,?> params)
Description copied from interface:DataSourceFactorySpi
Test to see if this factory is suitable for processing the data pointed to by the params map.If this data source requires a number of parameters then this mehtod should check that they are all present and that they are all valid.
- Specified by:
canProcess
in interfaceDataSourceFactorySpi
- Overrides:
canProcess
in classAbstractDataSourceFactorySpi
- Parameters:
params
- The full set of information needed to construct a live data source.- Returns:
- booean true if and only if this factory can process the resource indicated by the param set and all the required params are pressent.
-
createNewDataSource
public DataSource createNewDataSource(Map<String,?> params) throws IOException
Description copied from interface:DataSourceFactorySpi
Same asDataSourceFactorySpi.createDataSource(Map)
, but forces the creation of a new DataSource- Throws:
IOException
-
getDescription
public String getDescription()
Description copied from interface:DataSourceFactorySpi
Describe the nature of the data source constructed by this factory.A non localized description of this data store type.
- Returns:
- A human readable description that is suitable for inclusion in a list of available datasources.
-
getParametersInfo
public DataAccessFactory.Param[] getParametersInfo()
Description copied from interface:DataSourceFactorySpi
MetaData about the required Parameters (forDataSourceFactorySpi.createDataSource(Map)
).- Returns:
- Param array describing the Map for createDataStore
-
isAvailable
public boolean isAvailable()
Make sure a JNDI context is available- Returns:
- true if and only if this factory has all the appropriate jars on the classpath to create DataSource.
