module JavaLong: sig .. end
Support for long type and Long class.
Instance creation
val min_value : java_long
The smallest value for long values.
val max_value : java_long
The largest value for long values.
val make : java_long -> t
Operations
val byte_value : t -> java_byte
Returns the wrapped value, as a byte.
val double_value : t -> java_double
Returns the wrapped value, as a double.
val float_value : t -> java_float
Returns the wrapped value, as a float.
val int_value : t -> java_int
Returns the wrapped value, as an int.
val long_value : t -> java_long
Returns the wrapped value, as a long.
val short_value : t -> java_short
Returns the wrapped value, as a short.
val compare : java_long -> java_long -> java_int
Compares the passed values.
val compare_to : t -> t -> java_int
Compares the passed values.
val value_of : java_long -> t
Converts the passed bare long into a long wrapper; see
valueOf(...).
val parse_long : ?radix:java_int -> JavaString.t -> java_long
Converts the passed string into a long wrapper, using the passed
radix (defaulting to
10l); see
parseLong(...).
Raises Java_exception if the string is invalid
val decode : JavaString.t -> t
Converts the passed string into a long wrapper; see
decode(...).
Raises Java_exception if the string is invalid
val value_of_string : ?radix:java_int -> JavaString.t -> t
Converts the passed string into a long wrapper, using the passed
radix (defaulting to
10l); see
valueOf(...).
Raises Java_exception if the string is invalid
Null value
val null : t
The null value.
val is_null : t -> bool
is_null obj returns true iff obj is equal to null.
val is_not_null : t -> bool
is_not_null obj returns false iff obj is equal to null.
Miscellaneous
val wrap : t -> t option
wrap obj wraps the reference
obj into an option type:
Some x if obj is not null;
None if obj is null.
val unwrap : t option -> t
unwrap obj unwraps the option
obj into a bare reference:
Some x is mapped to x;
None is mapped to null.
