Uses of ValueLayout.OfAddressPREVIEW in java.lang.foreign
Modifier and TypeFieldDescriptionstatic final ValueLayout.OfAddressPREVIEW
ValueLayout.ADDRESS
A value layout constant whose size is the same as that of a machine address (size_t
), bit alignment set tosizeof(size_t) * 8
, byte order set toByteOrder.nativeOrder()
.static final ValueLayout.OfAddressPREVIEW
ValueLayout.ADDRESS_UNALIGNED
An unaligned value layout constant whose size is the same as that of a machine address (size_t
), and byte order set toByteOrder.nativeOrder()
.Modifier and TypeMethodDescriptionValueLayout.OfAddress.asUnbounded()
Returns an unbounded address layout with the same carrier, alignment constraint, name and order as this address layout, but with the specified pointee layout.ValueLayout.OfAddress.withBitAlignment
(long bitAlignment) Returns a memory layout of the same type with the same size and name as this layout, but with the specified alignment constraint (in bits).Returns a memory layout of the same type with the same size and alignment constraint as this layout, but with the specified name.Returns a value layout with the same carrier, alignment constraint and name as this value layout, but with the specified byte order.Modifier and TypeMethodDescriptionVaList.Builder.addVarg
