Method Details

createProjection

public Class<?> createProjection(Class<?> repositoryDomain)

Specified by:

createProjection in interface com.broadleafcommerce.common.extension.projection.ProjectionFactory

createProjection

public Class<?> createProjection(Class<?> repositoryDomain,
 String projectionName)

Specified by:

createProjection in interface com.broadleafcommerce.common.extension.projection.ProjectionFactory

getExistingProjectionType

public Class<?> getExistingProjectionType(Class<?> repositoryDomain)

Specified by:

getExistingProjectionType in interface com.broadleafcommerce.common.extension.projection.ProjectionFactory

getProjectionType

public static Class<?> getProjectionType(Class<?> repositoryDomain)

Provides basic detection of projection type based on if the entity class implements BusinessTypeAware.

Parameters:

repositoryDomain - The entity class to check for explicit projection declaration

Returns:

If implementing BusinessTypeAware, return the discovered projection. Otherwise, null.

getExistingProjectionType

@Nullable
protected Class<?> getExistingProjectionType(Class<?> repositoryDomain,
 boolean onlyIfDerived)

Try to ascertain if a known projection type already exists for the specified domain class. This could be a projection type noted on a superclass. Will return null if no projection type was able to be ascertained for the domain class, or any of its ancestors.

Parameters:

repositoryDomain - The domain class to inspect for determination of a referenced projection class

onlyIfDerived - Only attempt to determine the project type if it is explicitly declared in the repositoryDomain class (not a super class). Otherwise, return null.

Returns:

The identified projection class, or null if not found

shouldProject

protected boolean shouldProject(Class<?> type)

Whether or not the type for a field warrants a projection class. Primitive types, and standard types handled by Jackson can simply be copied to the containing projection class as field members without any special handling.

Parameters:

type - The field type in the domain class

Returns:

Whether or not the field type warrants a projection of its own

shouldIgnore

protected boolean shouldIgnore(Field field)

Whether or not the field from the domain class should be ignored and not copied into the projection.

Parameters:

field - The field to assess for inclusion

Returns:

Whether or not the field should be ignored
