Class EqualityUtils

java.lang.Object
  cz.cuni.mff.ksi.jinfer.base.utils.EqualityUtils

public final class EqualityUtils
extends Object

Utility class to test equalities in XML representation.

See the integer flags used to specified which features to ignore while comparing. Example usage:

EqualityUtils.sameElements(e1, e2, EqualityUtils.IGNORE_METADATA | EqualityUtils.IGNORE_NAME)

to ignore metadata and names of provided elements.

static int	IGNORE_METADATA While comparing, ignore AbstractNamedNode.getMetadata().
static int	IGNORE_NAME While comparing, ignore AbstractNamedNode.getName().
static int	IGNORE_SUBNODES While comparing, ignore Element.getSubnodes().

Method Summary

static boolean	sameElements(Element e1, Element e2, int ignore) Compares two elements, ignoring specified features.
static boolean	sameIntervals(RegexpInterval i1, RegexpInterval i2) Compare two intervals if they have equal minimum and maximum.

Method Detail

sameElements

public static boolean sameElements(Element e1,
                                   Element e2,
                                   int ignore)

Compares two elements, ignoring specified features.

Parameters:

e1 - Element 1 to compare.

e2 - Element 2 to compare.

ignore - Bitmap of flags to compare. Combine multiple flags with a bitwise OR (pipe character "|").

Returns:

True if provided elements are same, ignoring specified features.

sameSimpleData

public static boolean sameSimpleData(SimpleData sd1,
                                     SimpleData sd2,
                                     int ignore)

Compares two simple data, ignoring specified features.

Parameters:

sd1 - Simple data 1 to compare.

sd2 - Simple data 2 to compare.

ignore - Bitmap of flags to compare. Combine multiple flags with a bitwise OR (pipe character "|").

Returns:

True if provided simple data are same, ignoring specified features.

sameIntervals

public static boolean sameIntervals(RegexpInterval i1,
                                    RegexpInterval i2)

Compare two intervals if they have equal minimum and maximum. Intervals must not be null. If both intervals are unbounded and they have the same minimum, they are considered equal.

Parameters:

i1 - First interval to be compared.

i2 - Second interval to be compared.

Returns:

True if minimums and maximums of both intervals match, false otherwise.
