hasVaryingPersistedLengthInstances

public boolean hasVaryingPersistedLengthInstances()

Description copied from interface: PersistenceTypeDefinition

Provides information if one particular instance can have variing binary length from one store to another.

Examples for variable length instances:

• variable size collection instances
• variable size pesudo collection instances like java.util.StringBuilder
• instances of custom defined types similar to collections

Examples for fixed length instances:

• arrays
• all immutable type instances (like java.lang.String )
• all fixed length types (see PersistenceTypeDefinition.hasVaryingPersistedLengthInstances()
