The metadata for the value class, if the type is persistent.

Specified by:

getTypeMetaData in interface ValueMetaData

getDeclaredType

public Class getDeclaredType()

Description copied from interface: ValueMetaData

Return the declared class of the value. This can differ from the return value of ValueMetaData.getType() if the user indicates a different type or the value has an externalizer.

isEmbedded

public boolean isEmbedded()

Description copied from interface: ValueMetaData

This attribute is a hint to the implementation to store this value in the same structure as the class, rather than as a separate datastore structure.

Description copied from interface: ValueMetaData

This attribute is a hint to the implementation to store this value in the same structure as the class, rather than as a separate datastore structure.
