## org.biojava.bio.symbol
Class MergeLocation

      org.biojava.bio.symbol.AbstractLocation
          org.biojava.bio.symbol.AbstractRangeLocation
              org.biojava.bio.symbol.RangeLocation
                  org.biojava.bio.symbol.MergeLocation

All Implemented Interfaces:
  Serializable, Location

    public class MergeLocation

extends RangeLocation

Produced by LocationTools as a result of union operations. It's a `RangeLocation` and can be used as such but it also retains knowledge of which individual components made it up. None of the methods of RangeLocation are overridden only new methods have been added to get the subcomponents.

For example a union operation between the following locations [1,20],[27,45],[30-70] will produce a `CompoundLocation` like this: {[1,20],[27,70]}, the last two locations have been merged into a `MergeLocation` which contains the two subcomponents.

Method Detail

### getComponentList

    public List getComponentList(boolean recurse)

  Gets the component locations that make up this one

  Parameters:
    `recurse` - if true the method lists the component locations of all nested `MergedLocation`s.
  Returns:
    a `List` of `Location`s.

### componentLocationIterator

    public ListIterator componentLocationIterator()

  Returns:
    A `ListIterator` over the component locations. The iterator does not recurse nested MergeLocations.

### mergeLocations

    public static MergeLocation mergeLocations(List componentLocations)
                                        throws BioException

  Static Factory method for getting an instance of a `MergeLocation`

  Parameters:
    `componentLocations` - the `Locations to Merge`
  Returns:
    the merged location
  Throws:
    `BioException` - if the list contains objects that are not `Locations` or if the locations don't represent a contiguous block. Use `LocationTools.union()` if you want to merge discontinuous blocks.

### mergeLocations

    public static MergeLocation mergeLocations(Location locA,
                                               Location locB)
                                        throws BioException

  Throws:
    `BioException`
