Constructor Detail

AbstractJdbcPersonAttributeDao

public AbstractJdbcPersonAttributeDao()

AbstractJdbcPersonAttributeDao

public AbstractJdbcPersonAttributeDao(DataSource ds,
                              String queryTemplate)

Parameters:

ds - The DataSource to use for queries

queryTemplate - Template to use for SQL query generation. Use {0} as the placeholder for where the generated portion of the WHERE clause should be inserted.

Method Detail

getQueryTemplate

public String getQueryTemplate()

Returns:

the queryTemplate

getQueryType

public QueryType getQueryType()

Returns:

the queryType

setQueryType

public void setQueryType(QueryType queryType)

Type of logical operator to use when joining WHERE clause components

Parameters:

queryType - the queryType to set

parseAttributeMapFromResults

protected abstract List<IPersonAttributes> parseAttributeMapFromResults(List<R> queryResults,
                                                   String queryUserName)

Takes the List from the query and parses it into the List of IPersonAttributes attributes to be returned.

Parameters:

queryResults - Results from the query.

queryUserName - The username passed in the query map, if no username attribute existed in the query Map null is provided.

Returns:

The results of the query

getRowMapper

protected abstract org.springframework.jdbc.core.simple.ParameterizedRowMapper<R> getRowMapper()

Returns:

The ParameterizedRowMapper to handle the results of the SQL query.

appendAttributeToQuery

protected org.jasig.services.persondir.support.jdbc.PartialWhereClause appendAttributeToQuery(org.jasig.services.persondir.support.jdbc.PartialWhereClause queryBuilder,
                                                                                  String dataAttribute,
                                                                                  List<Object> queryValues)

Description copied from class: AbstractQueryPersonAttributeDao

Append the attribute and value to the queryBuilder.

Specified by:

appendAttributeToQuery in class AbstractQueryPersonAttributeDao<org.jasig.services.persondir.support.jdbc.PartialWhereClause>

Parameters:

queryBuilder - The sub-class specific query builder object

dataAttribute - The full attribute name to append

queryValues - The values for the data attribute

Returns:

An updated queryBuiler

canonicalizeDataAttributeForSql

protected String canonicalizeDataAttributeForSql(String dataAttribute)

Canonicalize the data-layer attribute column with the given name via SQL function. This is as opposed to canonicalizing query attributes or application attributes passed into or mapped out of the data layer. Canonicalization of a data-layer column should only be necessary if the data layer if you require case-insensitive searching on a mixed-case column in a case-sensitive data layer. Careful, though, as this can result in table scanning if the data layer does not support function-based indices.

Parameters:

dataAttribute -

Returns:

getPeopleForQuery

protected List<IPersonAttributes> getPeopleForQuery(org.jasig.services.persondir.support.jdbc.PartialWhereClause queryBuilder,
                                        String queryUserName)

Description copied from class: AbstractQueryPersonAttributeDao

Executes the query for the generated queryBuilder object and returns a list where each entry is a Map of attributes for a single IPersonAttributes.

Specified by:

getPeopleForQuery in class AbstractQueryPersonAttributeDao<org.jasig.services.persondir.support.jdbc.PartialWhereClause>

Parameters:

queryBuilder - The query generated by calls to AbstractQueryPersonAttributeDao.appendAttributeToQuery(Object, String, List)

queryUserName - The username passed in the query map, if no username attribute existed in the query Map null is provided.

Returns:

The list of IPersons found by the query. The user attributes should be using the raw names from the data layer.

getCaseInsensitiveDataAttributes

public Map<String,CaseCanonicalizationMode> getCaseInsensitiveDataAttributes()

setCaseInsensitiveDataAttributes

public void setCaseInsensitiveDataAttributes(Map<String,CaseCanonicalizationMode> caseInsensitiveDataAttributes)

setCaseInsensitiveDataAttributesAsCollection

public void setCaseInsensitiveDataAttributesAsCollection(Collection<String> caseInsensitiveDataAttributes)

setDataAttributeCaseCanonicalizationFunctions

public void setDataAttributeCaseCanonicalizationFunctions(Map<CaseCanonicalizationMode,MessageFormat> dataAttributeCaseCanonicalizationFunctions)

Assign MessageFormats describing how to wrap a JDBC/SQL column reference in a function corresponding to a given CaseCanonicalizationMode. For example, a typical mapping for CaseCanonicalizationMode.LOWER would be "lower({0})". The defaults are just what you'd expect ("lower({0})" and "upper({0})").

Setting null or an empty map has the effect of never wrapping any columns in canonicalizing functions, even if they are referenced by setCaseInsensitiveDataAttributes(java.util.Map).

Parameters:

dataAttributeCaseCanonicalizationFunctions -

getDataAttributeCaseCanonicalizationFunctions

public Map<CaseCanonicalizationMode,MessageFormat> getDataAttributeCaseCanonicalizationFunctions()
