Overview

Attribute values dimension

Handles comparison of attribute values. Supports :strict, :strip, :compact, :normalize, and :ignore behaviors.

Behaviors:

  • :strict - Exact attribute value comparison

  • :strip - Compare with leading/trailing whitespace removed

  • :compact - Compare with internal whitespace collapsed

  • :normalize - Compare with whitespace stripped and collapsed

  • :ignore - Skip attribute value comparison

#compare(data1, data2, behavior) ⇒ Boolean

Compare with custom behavior

Supports the extended behaviors for attribute values.

Parameters:

  • data1 (Object) —

    First data

  • data2 (Object) —

    Second data

  • behavior (Symbol) —

    Comparison behavior

Returns:

  • (Boolean) —

    true if data matches according to behavior

#compare_compact(attrs1, attrs2) ⇒ Boolean

Compact comparison

Compare with internal whitespace collapsed.

Parameters:

  • attrs1 (Hash) —

    First attributes hash

  • attrs2 (Hash) —

    Second attributes hash

Returns:

  all_keys.all? do |key|
    compact_whitespace(attrs1[key].to_s) == compact_whitespace(attrs2[key].to_s)
  end
end

#compare_normalize(attrs1, attrs2) ⇒ Boolean

Normalized comparison

Compare with whitespace stripped and collapsed.

Parameters:

  • attrs1 (Hash) —

    First attributes hash

  • attrs2 (Hash) —

    Second attributes hash

Returns:

  • (Boolean) —

    true if normalized values are equal

end

#compare_strict(attrs1, attrs2) ⇒ Boolean

Strict attribute value comparison

Parameters:

  • attrs1 (Hash) —

    First attributes hash

  • attrs2 (Hash) —

Compare with leading/trailing whitespace removed.

Parameters:
