Re: [concern-users] Transient values in subjects

[Manfred D. <mf...@ma...>]

Holger,

Thank you for the quick answer.

I'm using hibernate for the object. Some attributes of the class are
mapped as hibernate properties. Another attribute of this class isn't
mapped to a persistent field. Here is an example of such a class (see
hibernate-xdoclet-tags for persistent fields):

/**
 * Speicherung Dateien
 *
 * @hibernate.class 
 *  table="FILES"
 */
public class LoadFile implements Serializable {
    // Persistente Felder
    private Integer fileId;
    private String fileName;

    // Transiente Felder
    private String transientValue;

    /**
     * Objekt anlegen 
     */
    public LoadFile() {
        super();
    }


    /**
     * @return Returns the fileId.
     * 
     * @hibernate.id
     *          column="FILE_ID"
     *          generator-class="hilo"
     *          unsaved-value="null"
     * @hibernate.generator-param
     *          name="table"
     *          value="SEQUENCE_FILE"
     * @hibernate.generator-param
     *          name="column"
     *          value="IDX"
     */
    public Integer getFileId() {
        return fileId;
    }

    /**
     * @param fileId The fileId to set.
     */
    public void setFileId(Integer fileId) {
        this.fileId = fileId;
    }

    /**
     * @return Returns the fileName.
     * 
     * @hibernate.property
     *          column="FILE_NAME"
     *          length="256"    
     */
    public String getFileName() {
        return fileName;
    }

    /**
     * @param fileName The fileName to set.
     */
    public void setFileName(String fileName) {
        this.fileName = fileName;
    }

    /**
     * @return Returns the transientValue
     */
    public String getTransientValue() {
        return this.transientValue;
    }

    /**
     * @param transientValue The transientValue to set.
     */
    public void setTransientValue(String transientValue) {
        this.transientValue = transientValue;
    }
}

I'm new to con:cern. So may be I didn't understand how to do some things
right.

Manfred
