Method Detail

convertAttributeKeys

public Map<String,String> convertAttributeKeys(Map<String,String> attributesByName,
                                               String namespace)

Description copied from interface: KrmsAttributeDefinitionService

This method converts a collection of name/value attribute pairs to id/value attribute pairs.

At the api layer, attributes are represented as name/value pairs. However, in the database, the names of the attribute and the values are stored separately. The attribute definitions contain the attribute names. All defined attributes(for the various krms entity types) are stored together in a single table. The attribute values themselves are stored in separate tables for each entity type, and then reference the attribute definitions by the attribute definition id.

This method converts the name/value pairs to id/value pairs so they can be searched from a single table. This simplifies the queries for attributes.

Specified by:

convertAttributeKeys in interface KrmsAttributeDefinitionService

Parameters:

attributesByName - - a Map containing the name/value pairs for the set of attributes.

namespace - - the namespace code of the set of attributes

Returns:

a Map containing the id/value pairs for the set of attributes.

getKrmsAttributeId

public String getKrmsAttributeId(String attributeName,
                                 String namespace)

Description copied from interface: KrmsAttributeDefinitionService

This method gets the attribute definition ID for a given attribute

Specified by:

getKrmsAttributeId in interface KrmsAttributeDefinitionService

Parameters:

attributeName - - the name of the attribute

namespace - - the namespace code of the attribute

Returns:

- the attribute definition id

getKrmsAttributeBo

public org.kuali.rice.krms.impl.repository.KrmsAttributeDefinitionBo getKrmsAttributeBo(String attributeName,
                                                                                        String namespace)

Description copied from interface: KrmsAttributeDefinitionService

This method gets a KrmsAttributeDefinitionBo object for a given attribute.

Specified by:

getKrmsAttributeBo in interface KrmsAttributeDefinitionService

Parameters:

attributeName - - the name of the attribute

namespace - - the namespace code of the attribute

Returns:

- the attribute definition id

createAttributeDefinition

public KrmsAttributeDefinition createAttributeDefinition(KrmsAttributeDefinition attributeDefinition)

Description copied from interface: KrmsAttributeDefinitionService

This will create a KrmsAttributeDefinition exactly like the parameter passed in.

Specified by:

createAttributeDefinition in interface KrmsAttributeDefinitionService

Parameters:

attributeDefinition - - KrmsAttributeDefinition

updateAttributeDefinition

public void updateAttributeDefinition(KrmsAttributeDefinition attributeDefinition)

Description copied from interface: KrmsAttributeDefinitionService

This will update a KrmsAttributeDefinition.

Specified by:

getAttributeDefinitionById

public KrmsAttributeDefinition getAttributeDefinitionById(String id)

Description copied from interface: KrmsAttributeDefinitionService

Lookup a KrmsAttributeDefinition based on the given id.

Specified by:

getAttributeDefinitionById in interface KrmsAttributeDefinitionService

Parameters:

Returns:

a KrmsAttributeDefinition object with the given id. A null reference is returned if an invalid or non-existant id is supplied.

getAttributeDefinitionByNameAndNamespace

public KrmsAttributeDefinition getAttributeDefinitionByNameAndNamespace(String name,
                                                                        String namespace)

Description copied from interface: KrmsAttributeDefinitionService
