  • Method Details

    • addRelocation

      public void addRelocation(int type, int offset)
      Adds a relocation to this base relocation block.
      Parameters:
      type - the relocation type
      offset - the relocation offset

    • getVirtualAddress

      public int getVirtualAddress()
      Returns the base address of the relocations in this block.
      Returns:
      the base address of the relocations in this block

    • getSizeOfBlock

      public int getSizeOfBlock()
      Returns the size (in bytes) of this relocation block.
      Returns:
      the size (in bytes) of this relocation block

    • getCount

      public int getCount()
      Returns the number of relocation in this block.
      Returns:
      the number of relocation in this block

    • getOffset

      public int getOffset(int index)
      Returns the lower 12 bits of the offset.
      Parameters:
      index - the ith relocation
      Returns:
      int the offset of the relocation

    • getType

      public int getType(int index)
      Returns the upper 4 bits of the offset.
      Parameters:
      index - the ith relocation
      Returns:
      int the type of the relocation ,

    • toDataType

      public DataType toDataType() throws DuplicateNameException
      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.

      Specified by:
      toDataType in interface StructConverter
      Returns:
      returns a structure datatype representing the implementor of this interface
      Throws:
      DuplicateNameException - when a datatype of the same name already exists
      See Also:

    • toBytes

      public byte[] toBytes(DataConverter dc)
      Description copied from interface: ByteArrayConverter
      Returns a byte array representing this implementor of this interface.
      Specified by:
      toBytes in interface ByteArrayConverter
      Parameters:
      dc - the data converter to use
      Returns:
      a byte array representing this object
