Record Class XrExtent3DfKHR.Ptr

java.lang.Object
java.lang.Record
club.doki7.openxr.datatype.XrExtent3DfKHR.Ptr
All Implemented Interfaces:
IPointer, IXrExtent3DfKHR, Iterable<XrExtent3DfKHR>
Enclosing class:
XrExtent3DfKHR
@ValueBasedCandidate @UnsafeConstructor public static record XrExtent3DfKHR.Ptr(@NotNull MemorySegment segment) extends Record implements IXrExtent3DfKHR, Iterable<XrExtent3DfKHR>

Represents a pointer to / an array of XrExtent3DfKHR structure(s) in native memory.

Technically speaking, this type has no difference with XrExtent3DfKHR. This type is introduced mainly for user to distinguish between a pointer to a single structure and a pointer to (potentially) an array of structure(s). APIs should use interface IXrExtent3DfKHR to handle both types uniformly. See package level documentation for more details.

Contracts

The property segment() should always be not-null (segment != NULL && !segment.equals(MemorySegment.NULL)), and properly aligned to XrExtent3DfKHR.LAYOUT.byteAlignment() bytes. To represent null pointer, you may use a Java null instead. See the documentation of IPointer.segment() for more details.

The constructor of this class is marked as UnsafeConstructor, because it does not perform any runtime check. The constructor can be useful for automatic code generators.

  • Constructor Details

    • Ptr

      public Ptr(@NotNull @NotNull MemorySegment segment)
      Creates an instance of a Ptr record class.
      Parameters:
      segment - the value for the segment record component

  • Method Details

    • size

      public long size()

    • at

      @NotNull public @NotNull XrExtent3DfKHR at(long index)

      Returns (a pointer to) the structure at the given index.

      Note that unlike read series functions (IntPtr.read() for example), modification on returned structure will be reflected on the original structure array. So this function is called at to explicitly indicate that the returned structure is a view of the original structure.

    • at

      public XrExtent3DfKHR.Ptr at(long index, @NotNull @NotNull Consumer<@NotNull XrExtent3DfKHR> consumer)

    • write

      public void write(long index, @NotNull @NotNull XrExtent3DfKHR value)

    • reinterpret

      @Unsafe @NotNull public @NotNull XrExtent3DfKHR.Ptr reinterpret(long newSize)

      Assume the XrExtent3DfKHR.Ptr is capable of holding at least newSize structures, create a new view XrExtent3DfKHR.Ptr that uses the same backing storage as this XrExtent3DfKHR.Ptr, but with the new size. Since there is actually no way to really check whether the new size is valid, while buffer overflow is undefined behavior, this method is marked as Unsafe.

      This method could be useful when handling data returned from some C API, where the size of the data is not known in advance.

      If the size of the underlying segment is actually known in advance and correctly set, and you want to create a shrunk view, you may use slice(long) (with validation) instead.

    • offset

      @NotNull public @NotNull XrExtent3DfKHR.Ptr offset(long offset)

    • slice

      @NotNull public @NotNull XrExtent3DfKHR.Ptr slice(long start, long end)
      Note that this function uses the List.subList(int, int) semantics (left inclusive, right exclusive interval), not MemorySegment.asSlice(long, long) semantics (offset + newSize). Be careful with the difference

    • slice

      public XrExtent3DfKHR.Ptr slice(long end)

    • toArray

      public XrExtent3DfKHR[] toArray()

    • iterator

      @NotNull public @NotNull Iterator<XrExtent3DfKHR> iterator()
      Specified by:
      iterator in interface Iterable<XrExtent3DfKHR>

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • segment

      @NotNull public @NotNull MemorySegment segment()
      Returns the value of the segment record component.
      Specified by:
      segment in interface IPointer
      Returns:
      the value of the segment record component
