  - ### Method Detail

    - #### setBinary

          public void setBinary(boolean b)

      Set binary mode for this Content ResourceComparator. If this attribute is set to false, Resource content will be compared ignoring platform line-ending conventions. Default is `true`.
      Parameters:
        `b` - whether to compare content in binary mode.

    - #### isBinary

          public boolean isBinary()

      Learn whether this Content ResourceComparator is operating in binary mode.
      Returns:
        boolean binary flag.

    - #### resourceCompare

          protected int resourceCompare(Resource foo,
                                        Resource bar)

      Compare two Resources by content.
      Specified by:
        `resourceCompare` in class `ResourceComparator`
      Parameters:
        `foo` - the first Resource.
        `bar` - the second Resource.
      Returns:
        a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.
      Throws:
        `BuildException` - if I/O errors occur.
