getFindersFor

public List<org.springframework.roo.model.JavaSymbolName> getFindersFor(org.springframework.roo.addon.beaninfo.BeanInfoMetadata beanInfoMetadata,
                                                                        String plural,

Description copied from interface: DynamicFinderServices

This method provides a convenient generator for all possible combinations of finder method signatures.

Specified by:

getFindersFor in interface DynamicFinderServices

Parameters:

beanInfoMetadata - the metadata for the BeanInfoMetadata for which the finder signatures combinations are generated. (required)

plural - the pluralised form of the entity name, which is used for finder method names (required)

maxDepth - the depth of combinations used for finder signatures combinations (a depth of 2 will combine a maximum of two attributes from the BeanInfoMetadata (required)

Returns:

all possible finder method signatures for the given depth.

getJpaQueryFor

public String getJpaQueryFor(org.springframework.roo.model.JavaSymbolName finderName,
                             String plural,
                             org.springframework.roo.addon.beaninfo.BeanInfoMetadata beanInfoMetadata)

Description copied from interface: DynamicFinderServices

This method generates a named JPA query String to be used in JPA entity manager queries.

Specified by:

getJpaQueryFor in interface DynamicFinderServices

Parameters:

finderName - the finder method signature to use. Must be a valid signature. (required)

beanInfoMetadata - the metadata for the BeanInfoMetadata for which the finder signatures combinations were generated. (required)

Returns:

the String to be used in a JPA named query

getParameterNames

public List<org.springframework.roo.model.JavaSymbolName> getParameterNames(org.springframework.roo.model.JavaSymbolName finderName,
                                                                            String plural,

Description copied from interface: DynamicFinderServices

This method should be used in combination with #getJpaQueryFor(JavaSymbolName, BeanInfoMetadata) in order to find out about the parameter names used in the named JPA query.

Specified by:

getParameterNames in interface DynamicFinderServices

Parameters:

finderName - the finder method signature to use. Must be a valid signature. (required)

beanInfoMetadata - the metadata for the BeanInfoMetadata for which the finder signatures combinations were generated. (required)

Returns:

the JavaSymbolName array representing the parameter names for the finder method signature presented

getParameterTypes
