Examples of JDOMetaData

com.sun.jdo.api.persistence.enhancer.meta.JDOMetaData
Provides the JDO meta information neccessary for byte-code enhancement.
Please note: This interface deals with fully qualified names in the JVM notation, that is, with '/' as package separator character (instead of '.').
The following convention is used to specify the format of a given name: Something called ...
- name represents a non-qualified name (e.g. JDOPersistenceCapableName = "PersistenceCapable")
- type represents a Java-qualified class name (e.g. JDOPersistenceCapablePath = 'com.sun.jdo.spi.persistence.support.sqlstore.PersistenceCapable")
- path represents a JVM-qualified name (e.g. JDOPersistenceCapablePath = 'com/sun/jdo/spi/persistence/support/sqlstore/PersistenceCapable")
- sig (for signature) represents a JVM-qualified type-signature name (e.g. JDOPersistenceCapableSig = "Lcom/sun/jdo/spi/persistence/support/sqlstore/PersistenceCapable;")
