  • Constructor Details

    • PanamaMemoryType

      public PanamaMemoryType(long minimum, Long maximum, boolean is64Bit, boolean isShared)
      Creates a new PanamaMemoryType instance with just the type values.

      This constructor is used when the type information is already known and no native handle is needed for further operations.

      Parameters:
      minimum - the minimum number of memory pages
      maximum - the maximum number of memory pages (null if unlimited)
      is64Bit - true if this is 64-bit addressable memory
      isShared - true if this is shared memory

    • PanamaMemoryType

      public PanamaMemoryType(long minimum, Long maximum, boolean is64Bit, boolean isShared, int pageSizeLog2)
      Creates a new PanamaMemoryType instance with just the type values including page size.
      Parameters:
      minimum - the minimum number of memory pages
      maximum - the maximum number of memory pages (null if unlimited)
      is64Bit - true if this is 64-bit addressable memory
      isShared - true if this is shared memory
      pageSizeLog2 - the log2 of the page size (e.g. 16 for 65536 bytes)

    • PanamaMemoryType

      public PanamaMemoryType(long minimum, Long maximum, boolean is64Bit, boolean isShared, Arena arena, MemorySegment nativeHandle)
      Creates a new PanamaMemoryType instance with native handle and default page size.
      Parameters:
      minimum - the minimum number of memory pages
      maximum - the maximum number of memory pages (null if unlimited)
      is64Bit - true if this is 64-bit addressable memory
      isShared - true if this is shared memory
      arena - the memory arena for resource management
      nativeHandle - the native handle to the memory type

    • PanamaMemoryType

      public PanamaMemoryType(long minimum, Long maximum, boolean is64Bit, boolean isShared, int pageSizeLog2, Arena arena, MemorySegment nativeHandle)
      Creates a new PanamaMemoryType instance with native handle.
      Parameters:
      minimum - the minimum number of memory pages
      maximum - the maximum number of memory pages (null if unlimited)
      is64Bit - true if this is 64-bit addressable memory
      isShared - true if this is shared memory
      pageSizeLog2 - the log2 of the page size (e.g. 16 for 65536 bytes)
      arena - the memory arena for resource management
      nativeHandle - the native handle to the memory type

  • Method Details

    • fromNative

      public static PanamaMemoryType fromNative(MemorySegment nativeHandle, Arena arena)
      Creates a PanamaMemoryType from native memory type information.
      Parameters:
      nativeHandle - the native handle to the memory type
      arena - the memory arena for resource management
      Returns:
      the PanamaMemoryType instance
      Throws:
      IllegalArgumentException - if nativeHandle is invalid
