    • getNameOffset

      public int getNameOffset()
      The offset from the start of the section name table to the name of this section. A value of -1 indicates an unnamed section.
      Returns:
      the offset from the start of the section name table

    • getName

      public String getName()
      Returns the name of this section.
      Returns:
      the name of this section

    • getData

      public InputStream getData() throws IOException
      Returns an input stream to underlying bytes of this section.
      Returns:
      an input stream to underlying bytes of this section
      Throws:
      IOException - if an i/o error occurs.

    • getUnpackedData

      public byte[] getUnpackedData(TaskMonitor monitor) throws IOException

      Parameters:
      monitor - the task monitor
      Returns:
      the unpacked data
      Throws:
      IOException - if an i/o error occurs or the section is not packed.

      Returns the preferred address of this section.
      Returns:
      the preferred address of this section

    • getTotalLength

      public int getTotalLength()

    • getUnpackedLength

      public int getUnpackedLength()
      Returns the size in bytes of the "initialized" part of the contents.
      Returns:
      the size in bytes of the "initialized" part of the contents

    • getContainerLength

      public int getContainerLength()
      Returns the size in bytes of the raw data in the container.
      Returns:
      the size in bytes of the raw data in the container

    • getContainerOffset

      public byte getReservedA()
      Reserved!
      Returns:
      Reserved!

    • isRead

      public boolean isRead()
      Returns true if this section has read permissions.
      Returns:
      true if this section has read permissions

    • isWrite

      public boolean isWrite()
      Returns true if this section has write permissions.
      Returns:
      true if this section has write permissions

    • isExecute

      public boolean isExecute()
      Returns true if this section has execute permissions.
      Returns:
      true if this section has execute permissions

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • 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.

      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
      IOException - if an IO-related error occurs
