- Method Detail
  - compare
```
public int compare(TransMeta t1,
                   TransMeta t2)
```
    Compares two transformation on name, filename, repository directory, etc. The comparison algorithm is as follows:
    1. The first transformation's filename is checked first; if it has none, the transformation comes from a repository. If the second transformation does not come from a repository, -1 is returned.
    2. If the transformations are both from a repository, the transformations' names are compared. If the first transformation has no name and the second one does, a -1 is returned. If the opposite is true, a 1 is returned.
    3. If they both have names they are compared as strings. If the result is non-zero it is returned. Otherwise the repository directories are compared using the same technique of checking empty values and then performing a string comparison, returning any non-zero result.
    4. If the names and directories are equal, the object revision strings are compared using the same technique of checking empty values and then performing a string comparison, this time ultimately returning the result of the string compare.
    5. If the first transformation does not come from a repository and the second one does, a 1 is returned. Otherwise the transformation names and filenames are subsequently compared using the same technique of checking empty values and then performing a string comparison, ultimately returning the result of the filename string comparison.
    Specified by:
    
    compare in interface Comparator<TransMeta>
    
    Parameters:
    
    t1 - the first transformation to compare
    
    t2 - the second transformation to compare
    
    Returns:
    
    0 if the two transformations are equal, 1 or -1 depending on the values (see description above)
  - compareTo
```
public int compareTo(TransMeta o)
```
