Detailed Description

arbitrary 2x2 matrix Generated from class MR::Matrix2b.

Has the same layout as the C++ struct, the fields are accessed in place in native memory.

Constructor & Destructor Documentation

Matrix2b() [1/3]

meshlib.Matrix2b.Matrix2b	(	java.lang.foreign.MemorySegment	segment,
		java.lang.Object	owner )

Wraps a segment holding the struct. owner is kept alive as long as this wrapper is. Not for normal use.

Matrix2b() [2/3]

meshlib.Matrix2b.Matrix2b

(

)

Constructs an empty (default-constructed) instance.

Calls MR_Matrix2b_DefaultConstruct().

Matrix2b() [3/3]

meshlib.Matrix2b.Matrix2b	(	meshlib.Vector2b	x,
		meshlib.Vector2b	y )

initializes matrix from its 2 rows Generated from constructor MR::Matrix2b::Matrix2b. The reference to the parameter x might be preserved in the constructed object. The reference to the parameter y might be preserved in the constructed object.

Calls MR_Matrix2b_Construct().
