CATEGORY nulls
NullIfCloseTo
Returns null if the input value is within range of the specified value.
- double -> NullIfCloseTo(double: compareto, double: sigma) -> java.lang.Double
NullIfEmpty
Yields a null if the input String is empty. Throws an error if the input String is null.
- java.lang.String -> NullIfEmpty() -> java.lang.String
NullIfEq
Yeilds a null if the input value is equal to the specified value.
- double -> NullIfEq(double: compareto) -> java.lang.Double
- long -> NullIfEq(long: compareto) -> java.lang.Long
NullIfGe
Yields a null if the input value is greater tha or equal to the specified value.
- double -> NullIfGe(double: compareto) -> java.lang.Double
- long -> NullIfGe(long: compareto) -> java.lang.Long
NullIfGt
Yields a null if the input value is greater than the specified value.
- double -> NullIfGt(double: compareto) -> java.lang.Double
- long -> NullIfGt(long: compareto) -> java.lang.Long
NullIfLe
Yields a null if the input value is less than or equal to the specified value.
- double -> NullIfLe(double: compareto) -> java.lang.Double
- long -> NullIfLe(long: compareto) -> java.lang.Long
NullIfLt
Yields a null if the input value is equal to the specified value.
- double -> NullIfLt(double: compareto) -> java.lang.Double
- long -> NullIfLt(long: compareto) -> java.lang.Long
NullIfNullOrEmpty
Yield a null value if the input String is either null or empty.
- java.lang.String -> NullIfNullOrEmpty() -> java.lang.String
NullIfWithin
Yields a null if the input value is within the specified range, inclusive.
- double -> NullIfWithin(double: min, double: max) -> java.lang.Double
NullOrLoad
Reads a long variable from the input, hashes and scales it to the unit interval 0.0d - 1.0d, then uses the result to determine whether to return null object or a loaded value.
- long -> NullOrLoad(double: ratio, java.lang.String: varname) -> java.lang.Object
NullOrPass
Reads a long variable from the thread local variable map, hashes and scales it to the unit interval 0.0d - 1.0d, then uses the result to determine whether to return a null object or the input value.
- java.lang.Object -> NullOrPass(double: ratio, java.lang.String: varname) -> java.lang.Object
Unset
Always yields the VALUE.unset value, which signals to any consumers that the value provided should be considered undefined for any operation. This is distinct from functions which return a null, which is considered an actual value to be acted upon. It is deemed an error for any downstream user of this library to do anything with VALUE.unset besides explicitly acting like it wasn't provided. That is the point of VALUE.unset. The purpose of having such a value in this library is to provide a value type to help bridge between functional flows and imperative run-times. Without such a value, it would be difficult to simulate value streams in which some of the time values are set and other times they are not.
- long -> Unset() -> java.lang.Object
UnsetIfCloseTo
Yield VALUE.unset if the input value is close to the specified value by the sigma threshold. Otherwise, pass the input value along.
- double -> UnsetIfCloseTo(double: compareto, double: sigma) -> java.lang.Object
UnsetIfEmpty
Yield VALUE.unset if the input String is empty. Throws an error if the input value is null. Otherwise, passes the original value along.
- java.lang.String -> UnsetIfEmpty() -> java.lang.Object
UnsetIfEq
Yield UNSET.vale if the input value is equal to the specified value. Otherwise, pass the input value along.
- double -> UnsetIfEq(double: compareto) -> java.lang.Double
- long -> UnsetIfEq(long: compareto) -> java.lang.Object
UnsetIfGe
Yield VALUE.unset if the input value is greater than or equal to the specified value. Otherwise, pass the input value along.
- double -> UnsetIfGe(double: compareto) -> java.lang.Object
- long -> UnsetIfGe(long: compareto) -> java.lang.Object
UnsetIfGt
Yield UNSET.value if the input value is greater than the specified value. Otherwise, pass the input value along.
- double -> UnsetIfGt(double: compareto) -> java.lang.Object
- long -> UnsetIfGt(long: compareto) -> java.lang.Object
UnsetIfLe
Yield VALUE.unset if the input value is less than or equal to the specified value. Otherwise, pass the value along.
- double -> UnsetIfLe(double: compareto) -> java.lang.Object
- long -> UnsetIfLe(long: compareto) -> java.lang.Object
UnsetIfLt
Yield VALUE.unset if the provided value is less than the specified value, otherwise, pass the original value;
- double -> UnsetIfLt(double: compareto) -> java.lang.Object
- long -> UnsetIfLt(long: compareto) -> java.lang.Object
UnsetIfNullOrEmpty
Yields UNSET.value if the input value is null or empty. Otherwise, passes the original value along.
- java.lang.String -> UnsetIfNullOrEmpty() -> java.lang.Object
UnsetIfStringEq
Yields UNSET.value if the input value is equal to the specified value. Throws an error if the input value is null. Otherwise, passes the original value along.
- java.lang.String -> UnsetIfStringEq(java.lang.String: compareto) -> java.lang.Object
UnsetIfStringNe
Yields UNSET.value if the input String is not equal to the specified String value. Throws an error if the input value is null. Otherwise, passes the original value along.
- java.lang.String -> UnsetIfStringNe(java.lang.String: compareto) -> java.lang.Object
UnsetIfWithin
Yields UNSET.value if the input value is within the specified range, inclusive. Otherwise, passes the original value along.
- double -> UnsetIfWithin(double: min, double: max) -> java.lang.Object
UnsetOrLoad
Reads a long variable from the input, hashes and scales it to the unit interval 0.0d - 1.0d, then uses the result to determine whether to return UNSET.value or a loaded value.
- long -> UnsetOrLoad(double: ratio, java.lang.String: varname) -> java.lang.Object
UnsetOrPass
Reads a long variable from the thread local variable map, hashes and scales it to the unit interval 0.0d - 1.0d, then uses the result to determine whether to return UNSET.value or the input value.
- java.lang.Object -> UnsetOrPass(double: ratio, java.lang.String: varname) -> java.lang.Object
