    • Method Detail

      • readName

        protected void readName​(BinaryReader reader)
                 throws java.io.IOException
        Throws:
        java.io.IOException

      • getName

        public java.lang.String getName()
        Returns the section name. The section name will never be more than eight characters.
        Returns:
        the section name

      • getPhysicalAddress

        public int getPhysicalAddress()
        Returns the physical address offset. This is the address at which the section should be loaded into memory and reflects a addressable word offset. For linked executables, this is the absolute address within the program space. For unlinked objects, this address is relative to the object's address space (i.e. the first section is always at offset zero).
        Returns:
        the physical address

      • move

        public void move​(int offset)
        Adds offset to the physical address; this must be performed before relocations in order to achieve the proper result.
        Parameters:
        offset - the offset to add to the physical address

      • getPhysicalAddress

        public Address getPhysicalAddress​(Language language)
        Returns the physical address. This is the address at which the section should be loaded into memory. For linked executables, this is the absolute address within the program space. For unlinked objects, this address is relative to the object's address space (i.e. the first section is always at offset zero).
        Returns:
        the physical address

      • getVirtualAddress

        public int getVirtualAddress()
        Returns the virtual address. This value is always the same as s_paddr.

        the virtual address

      • isExplicitlyByteAligned

        public boolean isExplicitlyByteAligned()
        Returns true if this section is byte oriented and aligned and should assume an addressable unit size of 1.

      • getSize

        public int getSize​(Language language)
        Returns the number of bytes of data stored in the file for this section. NOTE: This value does not strictly indicate size in bytes. For word-oriented machines, this value is represents size in words.
        Returns:
        the number of bytes of data stored in the file for this section

      • getPointerToRawData

        Returns the number of line number entries for this section.
        Returns:
        the number of line number entries for this section

      • getFlags

        public int getFlags()
        Returns the flags for this section.
        Returns:
        the flags for this section

      • getReserved

        public short getReserved()

      • getPage

        public short getPage()

      • getRawDataStream

        public java.io.InputStream getRawDataStream​(ByteProvider provider,
                                            Language language)
                                     throws java.io.IOException
        Returns an input stream that will supply the bytes for this section.
        Returns:
        the input stream
        Throws:
        java.io.IOException - if an I/O error occurs

      • toDataType

        public DataType toDataType()
                    throws DuplicateNameException,
                           java.io.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
        java.io.IOException

      • getAddress

        public static Address getAddress​(Language language,

                                 CoffSectionHeader section)
        Convert address offset to an Address object. The default data space (defined by pspec) will be used if section is null or corresponds to a data section. The language default space (defined by slaspec) will be used for all non-data sections. If pspec does not specify a default data space, the default language space is used.
        Parameters:
        language -
        offset - address offset (byte offset assumed if section is null or is not explicitly byte aligned, otherwise word offset assumed).
        section - section which contains the specified offset or null (data space assumed)
        Returns:
        address object

      • getAddress

                                 AddressSpace space)
        Convert address offset to an Address in the specified space (defined by pspec). If pspec does not specify a default data space, the default language space is used.
        Parameters:
        language -
        offset - address offset (word offset assumed).
        space - address space
        Returns:
