value. This
expression can be implemented using a lambda, or it can be a result of
another operation. It has additional methods for operating on it.Function

default int |
compare(T first,
T second) |
default <V> ToStringNullable<V> |
compose(Function<? super V,? extends T> before)
Returns a composed expression that first applies the
before
function to its input, and then applies this function to the result. |
default ExpressionType |
expressionType()
Returns the expression type of this expression.
|
default long |
hash(T object)
Hash the specified object into a 64-bit hash.
|
default ToString<T> |
map(UnaryOperator<String> mapper)
Returns an expression for the value of this expression mapped using the
specified mapping function.
|
static <T> ToString<T> |
of(Function<T,String> lambda)
Returns a typed
ToString<T> using the provided lambda . |
default ToString<T> |
toLowerCase()
Returns an expression that is equivalent to this expression, except that
results are always in lower-case letters.
|
default ToString<T> |
toUpperCase()
Returns an expression that is equivalent to this expression, except that
results are always in upper-case letters.
