Method Detail

matchesSafely

public boolean matchesSafely(java.math.BigDecimal item)

Description copied from class: TypeSafeMatcher

Subclasses should implement this. The item will already have been checked for the specific type and will never be null.

Specified by:

matchesSafely in class TypeSafeMatcher<java.math.BigDecimal>

describeMismatchSafely

public void describeMismatchSafely(java.math.BigDecimal item,
                                   Description mismatchDescription)

Description copied from class: TypeSafeMatcher

Subclasses should override this. The item will already have been checked for the specific type and will never be null.

Overrides:

describeMismatchSafely in class TypeSafeMatcher<java.math.BigDecimal>

describeTo

public void describeTo(Description description)

Description copied from interface: SelfDescribing

Generates a description of the object. The description may be part of a a description of a larger object of which this is just a component, so it should be worded appropriately.

Parameters:

description - The description to be built or appended to.

closeTo

public static Matcher<java.math.BigDecimal> closeTo(java.math.BigDecimal operand,
                                                    java.math.BigDecimal error)

Creates a matcher of BigDecimals that matches when an examined BigDecimal is equal to the specified operand, within a range of +/- error. The comparison for equality is done by BigDecimals BigDecimal.compareTo(java.math.BigDecimal) method. For example:

assertThat(new BigDecimal("1.03"), is(closeTo(new BigDecimal("1.0"), new BigDecimal("0.03"))))

Parameters:

operand - the expected value of matching BigDecimals

error - the delta (+/-) within which matches will be allowed
