- 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)
```
    Compares this transformation's meta-data to the specified transformation's meta-data. This method simply calls compare(this, o)
    
    Specified by:
    
    compareTo in interface Comparable<TransMeta>
    
    Parameters:
    
    o - the o
    
    Returns:

    See Also:

  - equals
```
public boolean equals(Object obj)
```
    Checks whether this transformation's meta-data object is equal to the specified object. If the specified object is not an instance of TransMeta, false is returned. Otherwise the method returns whether a call to compare() indicates equality (i.e. compare(this, (TransMeta)obj)==0).
    
    Specified by:
    
    equals in interface Comparator<TransMeta>
    
    Overrides:
    
    equals in class Object

    a clone of the transformation meta-data object
    
    See Also:
    
    Object.clone()
  - realClone
```
public Object realClone(boolean doClear)
```
    Perform a real clone of the transformation meta-data object, including cloning all lists and copying all values. If the doClear parameter is true, the clone will be cleared of ALL values before the copy. If false, only the copied fields will be cleared.
    
    Parameters:
    
    doClear - Whether to clear all of the clone's data before copying from the source object
    
    Returns:
    
    a real clone of the calling object
