      public AddressSetView getAllInitializedAddressSet()
      Description copied from interface: Memory
      Returns the set of addresses which correspond to all memory blocks that have initialized data. This includes initialized memory blocks that contain data from the program's file header that are not actually in the running in memory image, such as debug sections. Use Memory.getLoadedAndInitializedAddressSet() if you only want the addressed of the loaded in memory blocks.

    • isExternalBlockAddress

      public boolean isExternalBlockAddress(Address addr)
      Description copied from interface: Memory
      Determine if the specified address is contained within the reserved EXTERNAL block (see MemoryBlock.EXTERNAL_BLOCK_NAME). This artificial memory block has certain limitations that may require associated addresses to be properly identified. All data access/referencing has the biggest exposure since the importers generally allocate a fixed and possibly insufficient amount of memory to corresponding data symbols. Any pointer math performed based upon an EXTERNAL block symbol address is likely to produce an unuseable address that may collide with unrelated symbols stored within the memory block (e.g., OffsetReference is one such example).
      Specified by:
      isExternalBlockAddress in interface Memory
      Parameters:
      addr - address
      Returns:
      true if address is contained within EXTERNAL memory block, else false.

      Create an initialized memory block initialized and add it to this Memory. All bytes will be initialized to the specified value (NOTE: use of zero as the initial value is encouraged for reduced storage).

      Overlay Blocks: An overlay memory block may be created in two ways:

      • Specifying a start address within an existing overlay address space (overlay parameter is ignored), or
      • Specifying a start address within a physical memory address space and passing overlay=true. This use case will force the creation of a new unique overlay address space.
      Specified by:
      createInitializedBlock in interface Memory
      Parameters:
      name - block name (See Memory.isValidMemoryBlockName(String) for naming rules)

      size - block length (positive non-zero value required)
      initialValue - initialization value for every byte in the block.
      monitor - progress monitor, may be null.
      overlay - if true, the block will be created as an OVERLAY block. If the start address is a non-overlay memory address a new overlay address space will be created and the block will have a starting address at the same offset within the new overlay space. If the specified start address is an overlay address an overlay block will be created at that overlay address.
      Returns:

    • createFileBytes

      public FileBytes createFileBytes(String filename, long offset, long size, InputStream is, TaskMonitor monitor) throws IOException, CancelledException
      Description copied from interface: Memory
      Stores a sequence of bytes into the program. Typically, this method is used by importers to store the original raw program bytes.
      Specified by:
      createFileBytes in interface Memory
      Parameters:
      filename - the name of the file from where the bytes originated
      offset - the offset into the file for the first byte in the input stream.
      size - the number of bytes to store from the input stream.
      is - the input stream that will supply the bytes to store in the program. Caller is responsible for closing input stream upon return.
      monitor - task monitor
      Returns:
      a FileBytes that was created to access the bytes.
      Throws:
      IOException - if there was an IOException saving the bytes to the program database.
      CancelledException - if the user cancelled this operation. Note: the database will be stable, but the buffers may contain 0s instead of the actual bytes.

    • getAllFileBytes

      public List<FileBytes> getAllFileBytes()
      Description copied from interface: Memory
      Returns a list of all the stored original file bytes objects

    • deleteFileBytes

      public boolean deleteFileBytes(FileBytes fileBytes) throws IOException
      Description copied from interface: Memory
      Deletes a stored sequence of file bytes. The file bytes can only be deleted if there are no memory block references to the file bytes.
      Specified by:

      Parameters:
      fileBytes - the FileBytes for the file bytes to be deleted.
      Returns:
      true if the FileBytes was deleted. If any memory blocks are referenced by this FileBytes or it is invalid then it will not be deleted and false will be returned.
      Throws:
      IOException - if there was an error updating the database.
