setOriginal

void setOriginal()

Sets current values as original values in primary key columns.

isModified

boolean isModified()

Returns:

true if object was modified since last database operation.

isDeleted

boolean isDeleted()

isDeleted flag is cleared when primary key columns are modified

Returns:

true if delete() method was executed.

clear
