getDataSourceProperties

public List<DataSourceProperty> getDataSourceProperties(Map<String,Object> parameters)

Description copied from interface: DataSourceService

Create the properties used in the template.

Specified by:

getDataSourceProperties in interface DataSourceService

Overrides:

getDataSourceProperties in class DefaultDataSourceService

Parameters:

parameters - parameters used for this request

Returns:

the list of DataSourceProperty instances to use in the template

checkFetchDatasourceAccess

public void checkFetchDatasourceAccess(Map<String,String> parameter)

Description copied from interface: DataSourceService

This method allows to implement a security access to a DataSource when it is used fetch() method. It can be overridden in specific DataSources to apply a particular security mechanism.

Specified by:

checkFetchDatasourceAccess in interface DataSourceService

Overrides:

checkFetchDatasourceAccess in class BaseDataSourceService

getCount

protected int getCount(Map<String,String> parameters)

Description copied from class: ReadOnlyDataSourceService

Returns the count of objects based on the passed parameters.

Specified by:

getCount in class ReadOnlyDataSourceService

Parameters:

parameters - the parameters passed in from the request

Returns:

the total number of objects

getGroupedCount

protected int getGroupedCount(org.hibernate.query.Query<javax.persistence.Tuple> countQuery)

getData

protected List<Map<String,Object>> getData(Map<String,String> parameters,
                                                 int startRow,
                                                 int endRow)

Description copied from class: ReadOnlyDataSourceService

Read/create the set of data as a list of Maps with key-value pairs.

Specified by:

getData in class ReadOnlyDataSourceService

Parameters:

parameters - the parameters passed in from the request

startRow - the first row to read (maybe -1 to indicate no startrow)

endRow - the last row to read (maybe -1 to indicate no endrow

Returns:

the number of objects read, note that this maybe more than endRow - startRow + 1. The startRow parameter should be strictly followed though.
