Record Class XrFoveationConfigurationHTC.Ptr

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

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

Technically speaking, this type has no difference with XrFoveationConfigurationHTC. 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 IXrFoveationConfigurationHTC 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 XrFoveationConfigurationHTC.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 XrFoveationConfigurationHTC 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 XrFoveationConfigurationHTC.Ptr at(long index, @NotNull @NotNull Consumer<@NotNull XrFoveationConfigurationHTC> consumer)

    • write

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

    • reinterpret

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

      Assume the XrFoveationConfigurationHTC.Ptr is capable of holding at least newSize structures, create a new view XrFoveationConfigurationHTC.Ptr that uses the same backing storage as this XrFoveationConfigurationHTC.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 XrFoveationConfigurationHTC.Ptr offset(long offset)

    • slice

      @NotNull public @NotNull XrFoveationConfigurationHTC.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 XrFoveationConfigurationHTC.Ptr slice(long end)

    • toArray

      public XrFoveationConfigurationHTC[] toArray()

    • iterator

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

    • 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
