Method Detail

greaterThan

public static <T extends java.lang.Number> <any> greaterThan(double val)

Creates a predicate comparing a given number with val. A number of null passed to the predicate will always return false.

greaterThanOrEqual

public static <T extends java.lang.Number> <any> greaterThanOrEqual(double val)

Creates a predicate comparing a given number with val. A number of null passed to the predicate will always return false.

lessThan

public static <T extends java.lang.Number> <any> lessThan(double val)

Creates a predicate comparing a given number with val. A number of null passed to the predicate will always return false.

lessThanOrEqual

public static <T extends java.lang.Number> <any> lessThanOrEqual(double val)

Creates a predicate comparing a given number with val. A number of null passed to the predicate will always return false.

equalsApproximately

public static <T extends java.lang.Number> <any> equalsApproximately(java.lang.Number val,
                                                                     double delta)

Creates a predicate comparing a given number with val. A number of null passed to the predicate will always return false.

equalsApproximately

public static <T extends java.lang.Number> <any> equalsApproximately(java.lang.Number val)
