Method Detail

getEntityAliases

protected final EntityAliases[] getEntityAliases()

Description copied from class: Loader

Get the result set descriptor

Specified by:

getEntityAliases in class Loader

getCollectionAliases

protected final CollectionAliases[] getCollectionAliases()

Specified by:

getCollectionAliases in class Loader

getSuffixes

protected abstract java.lang.String[] getSuffixes()

getCollectionSuffixes

protected abstract java.lang.String[] getCollectionSuffixes()

postInstantiate

protected void postInstantiate()

Description copied from class: Loader

Overrides:

postInstantiate in class Loader

generateSuffixes

public static java.lang.String[] generateSuffixes(int length)

Utility method that generates 0_, 1_ suffixes. Subclasses don't necessarily need to use this algorithm, but it is intended that they will in most cases.

Parameters:

length - The number of suffixes to generate

Returns:

The array of generated suffixes (with length=length).
