Detailed Description

Stores either a single double or nothing.

Instances created here own their C++ objects, see CppObject.

Constructor & Destructor Documentation

std_optional_double() [1/4]

meshlib.std_optional_double.std_optional_double	(	java.lang.foreign.MemorySegment	ptr,
		boolean	owned,
		java.lang.Object	owner )

Wraps a pointer from the C bindings. If owned, the object is destroyed when the wrapper dies. owner is kept alive as long as this wrapper is. Not for normal use.

std_optional_double() [2/4]

meshlib.std_optional_double.std_optional_double

(

)

Constructs an empty (default-constructed) instance.

Calls MR_std_optional_double_DefaultConstruct().

std_optional_double() [3/4]

meshlib.std_optional_double.std_optional_double

(

meshlib.std_optional_double

other

)

Constructs a copy of another instance. The source remains alive. The reference to the parameter other might be preserved in the constructed object.

Calls MR_std_optional_double_ConstructFromAnother().

std_optional_double() [4/4]

meshlib.std_optional_double.std_optional_double

(

java.lang.Double

other

)

Constructs a new instance.

Calls MR_std_optional_double_ConstructFrom().

Member Function Documentation

assignFrom()

void meshlib.std_optional_double.assignFrom

(

java.lang.Double

other

)

Assigns the contents.

Calls MR_std_optional_double_AssignFrom().

assignFromAnother()

void meshlib.std_optional_double.assignFromAnother

(

meshlib.std_optional_double

other

)

Assigns the contents from another instance. Both objects remain alive after the call. The reference to the parameter other might be preserved in this object.

Calls MR_std_optional_double_AssignFromAnother().

has_value()

boolean meshlib.std_optional_double.has_value

(

)

Returns true if this instance stores an object, as opposed to being empty.

Calls MR_std_optional_double_has_value().

value()

java.lang.Double meshlib.std_optional_double.value

(

)

The stored element or null if none, read-only. The reference to this object might be preserved as the return value.

Calls MR_std_optional_double_value().

value_mut()

java.lang.foreign.MemorySegment meshlib.std_optional_double.value_mut

(

)

The stored element or null if none, mutable. The reference to this object might be preserved as the return value.

Calls MR_std_optional_double_value_mut(). Some types are raw C types, see the C bindings for the details.
