Field Detail

cloneMethod

private static java.lang.reflect.Method cloneMethod

EMPTY_BOOL_ARRAY

public static final boolean[] EMPTY_BOOL_ARRAY

EMPTY_INT_ARRAY

public static final int[] EMPTY_INT_ARRAY

EMPTY_OBJECT_ARRAY

public static final java.lang.Object[] EMPTY_OBJECT_ARRAY

EMPTY_STRING_ARRAY

public static final java.lang.String[] EMPTY_STRING_ARRAY

MISSING

public static java.lang.Object MISSING

An object that can be used to represent a missing value. For example, a Map's get(key) function will return null under either of two circumstances: (1) the key was not found or (2) the key was associated with a null value. Instead of using null as an ambiguous result, MISSING can be returned in the case of the missing key in such circumstances.

Method Detail

all

public static <T> boolean all(java.lang.Iterable<T> items,
                              java.util.function.Predicate<T> test)

Returns true if the test function returns true for all of the items in the iterable.

any

public static <T> boolean any(java.lang.Iterable<T> items,
                              java.util.function.Predicate<T> test)

Returns true if the test function returns true for any of the items in the iterable.

asBool

public static boolean asBool(java.lang.Object obj)

If obj is a boolean, its value is returned. If obj is null, an empty array, or a number, char or byte representing 0, the return value is False. If obj is a string, then it is evaluated as described in AsBool(string) Otherwise the return value is the the result of AsBool(string) applied to obj.ToString()
