    • getMaxProtection

      public int getMaxProtection()
      Returns a octal model value reflecting the segment's maximum protection value allowed. For example: 7 -> 0x111 -> rwx 5 -> 0x101 -> rx
      Returns:
      the maximum protections of a segment

    • getInitProtection

      public int getInitProtection()
      Returns a octal model value reflecting the segment's initial protection value. For example: 7 -> 0x111 -> rwx 5 -> 0x101 -> rx
      Returns:
      the initial protections of a segment

    • isRead

      public boolean isRead()
      Returns true if the initial protections include READ.
      Returns:
      true if the initial protections include READ

    • isWrite

      public boolean isWrite()
      Returns true if the initial protections include WRITE.
      Returns:
      true if the initial protections include WRITE

    • isExecute

      public boolean isExecute()
      Returns true if the initial protections include EXECUTE.
      Returns:
      true if the initial protections include EXECUTE

    • getNumberOfSections

      public int getNumberOfSections()

    • getFlags

      public int getFlags()

    • isAppleProtected

      public boolean isAppleProtected()

    • contains

      public boolean contains(long addr)
      Returns true if the segment contains the given address
      Parameters:
      addr - The address to check
      Returns:
      True if the segment contains the given address; otherwise, false

    • toDataType

      public DataType toDataType() throws DuplicateNameException, IOException
      Description copied from interface: StructConverter
      Returns a structure datatype representing the contents of the implementor of this interface.

      For example, given: 

       class A {
     int foo;
     double bar;
 }

      The return value should be a structure data type with two data type components; an INT and a DOUBLE. The structure should contain field names and, if possible, field comments.

      Returns:
      returns a structure datatype representing the implementor of this interface
      Throws:
      DuplicateNameException - when a datatype of the same name already exists
      IOException - if an IO-related error occurs

      Gets the name of this load command
      Specified by:
      getCommandName in class LoadCommand
      Returns:
      The name of this load command

    • markupRawBinary

      public void markupRawBinary(MachHeader header, FlatProgramAPI api, Address baseAddress, ProgramModule parentModule, TaskMonitor monitor, MessageLog log)
      Description copied from class: LoadCommand
      Marks-up this LoadCommand with data structures and comments. Assumes the program was imported as a Raw Binary.
      Overrides:
