DatabaseChangeLog parse(String physicalChangeLogLocation,
                        ChangeLogParameters changeLogParameters,
                        ResourceAccessor resourceAccessor)
                 throws ChangeLogParseException
```
    Parses a Liquibase database changelog and returns the parsed form as an object.
    
    Parameters:
    
    physicalChangeLogLocation - the physical location of the changelog. The exact file formats and locations where can load changelog files from depend on the implementations and capabilities of the implementing parsers.
    
    changeLogParameters - parameters given by the end user that should be applied while parsing the changelog (i.e. replacement of ${placeholders} inside the changelogs with user-defined content)
    
    resourceAccessor - a Java resource accessor
    
    Returns:
    
    the parsed ChangeLog in object form
    
    Throws:
    
    ChangeLogParseException - if an error occurs during parsing of the ChangeLog
  - supports
```
boolean supports(String changeLogFile,
                 ResourceAccessor resourceAccessor)
```
    Checks if the file format is supported by an implementing ChangeLogParser and returns true if that is the case.
    
    Parameters:
    
    changeLogFile - the location of the changelog file
    
    resourceAccessor - the resource accessor
    
    Returns:
    
    true if the file format is supported, false if it is not.
