InterfacesInterfacePreview Feature描述Unnamed Patterns and VariablesA tree node for a binding pattern that matches a pattern with a variable of any name and a type of the match candidate; an unnamed pattern.String TemplatesA tree node for a string template expression.Foreign Function & Memory APIA value layout used to model the address of some region of memory.Foreign Function & Memory APIAn arena controls the lifecycle of native memory segments, providing both flexible allocation and timely deallocation.Foreign Function & Memory APIA function descriptor models the signature of a foreign function.Foreign Function & Memory APIA compound layout that is an aggregation of multiple, heterogeneous member layouts.Foreign Function & Memory APIA linker provides access to foreign functions from Java code, and access to Java code from foreign functions.Foreign Function & Memory APIA linker option is used to provide additional parameters to a linkage request.Foreign Function & Memory APIA memory layout describes the contents of a memory segment.Foreign Function & Memory APIAn element in a layout path.Foreign Function & Memory APIA memory segment provides access to a contiguous region of memory.Foreign Function & Memory APIA scope models the lifetime of all the memory segments associated with it.Foreign Function & Memory APIA padding layout.Foreign Function & Memory APIAn object that may be used to allocate memory segmentsPREVIEW.Foreign Function & Memory APIA compound layout that denotes a homogeneous repetition of a given element layout.Foreign Function & Memory APIA group layout whose member layouts are laid out one after the other.Foreign Function & Memory APIA symbol lookup retrieves the address of a symbol in one or more libraries.Foreign Function & Memory APIA group layout whose member layouts are laid out at the same starting offset.Foreign Function & Memory APIA layout that models values of basic data types.Foreign Function & Memory APIA value layout whose carrier is
boolean.class.Foreign Function & Memory APIA value layout whose carrier isbyte.class.Foreign Function & Memory APIA value layout whose carrier ischar.class.Foreign Function & Memory APIA value layout whose carrier isdouble.class.Foreign Function & Memory APIA value layout whose carrier isfloat.class.Foreign Function & Memory APIA value layout whose carrier isint.class.Foreign Function & Memory APIA value layout whose carrier islong.class.Foreign Function & Memory APIA value layout whose carrier isshort.class.String TemplatesStringTemplatePREVIEW is the run-time representation of a string template or text block template in a template expression.String TemplatesThis interface describes the methods provided by a generalized string template processor.String TemplatesBuilt-in policies using this additional interface have the flexibility to specialize the composition of the templated string by returning a customizedMethodHandlefromlinkagePREVIEW.Structured ConcurrencyRepresents a subtask forked withStructuredTaskScope.fork(Callable)PREVIEW.
