org.dbunit.dataset.datatype.NumberTolerantDataType

public class NumberTolerantDataType
extends NumberDataType

Extended version of the NumberDataType. Extends the AbstractDataType.compare(Object, Object) method in order to respect precision tolerance. This is comparable to the JUnit method assert(double val1, double val2, double toleratedDelta).

2.3.0

Method Details

getToleratedDelta

public ToleratedDeltaMap.Precision getToleratedDelta()

Returns the tolerated delta used for the comparison.

Returns:

the tolerated delta used for the comparison.

compareNonNulls

protected int compareNonNulls(Object value1cast,
 Object value2cast)
                       throws TypeCastException

The only method overwritten from the base implementation to compare numbers allowing a tolerance

Overrides:

compareNonNulls in class AbstractDataType

Parameters:

value1cast - First value resulting from the DataType.typeCast(Object) method call

value2cast - Second value resulting from the DataType.typeCast(Object) method call

Returns:

The result of the Comparable.compareTo(Object) invocation.

Throws:

TypeCastException - if either value cannot be cast to a Comparable.

• AbstractDataType.compareNonNulls(java.lang.Object, java.lang.Object)

isZero

public static final boolean isZero(BigDecimal value)

Checks if the given value is zero.

Parameters:

value - the value to check.

Returns:

true if and only if the given value is zero.
