An automatic field is a field which values are automatically generated from the FRAMEWORK (like a sequence in a DATABASE). Automatic field values are generated the first time a SqlPersistentObject is saved on the DATABASE and once created are not updatable. An automatic field can be used as primary key for a SqlPersistentObject because its value is guarantee to be unique. By default a field is not automatic. Parameters:   isAutomatic - setAutomaticType public void setAutomaticType(AutomaticType automaticType)(Code) setDynamic public void setDynamic(boolean b)(Code) Sets this field to be dynamically calculated or not. Parameters:   b - setExternal public void setExternal(boolean isExternallyManaged)(Code) Sets the field to be external (f.e. from a different table) or not. An external field of a persistent object will not be updatable into the DATABASE. By default a field is not external. setName public void setName(String name)(Code) setParamValue public void setParamValue(Object fieldValue, PreparedStatement pstmt, int paramIndex) throws SQLException(Code) setSize public void setSize(String size)(Code) setUseCache public void setUseCache(boolean useCache)(Code) setVisible public void setVisible(boolean visible)(Code) toString public String toString()(Code) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
