    • Method Detail

      • isBigEndian

        boolean isBigEndian()
        Returns:
        true if data stored big-endian byte order
      • getPointerSize

        int getPointerSize()
        Returns:
        the size of a pointer data type in bytes.
      • getPointerShift

        int getPointerShift()
        Shift amount affects interpretation of in-memory pointer values only and will also be reflected within instruction pcode. A value of zero indicates that shifted-pointers are not supported.

      • isSignedChar

        boolean isSignedChar()
        Returns:
        true if the "char" type is signed
      • getCharSize

        int getCharSize()
        Returns:
        the size of a char (char) primitive data type in bytes.
      • getWideCharSize

        int getWideCharSize()
        Returns:
        the size of a wide-char (wchar_t) primitive data type in bytes.
      • getShortSize

        int getShortSize()
        Returns:
        the size of a short primitive data type in bytes.
      • getIntegerSize

        int getIntegerSize()
        Returns:
        the size of a int primitive data type in bytes.
      • getLongSize

        int getLongSize()
        Returns:
        the size of a long primitive data type in bytes.
      • getLongLongSize

        int getLongLongSize()
        Returns:
        the size of a long long primitive data type in bytes.
      • getFloatSize

        int getFloatSize()
        Returns:
        the size of a float primitive data type in bytes.
      • getDoubleSize

        int getDoubleSize()
        Returns:
        the size of a double primitive data type in bytes.
      • getLongDoubleSize

        int getLongDoubleSize()
        Returns:
        the size of a long double primitive data type in bytes.
      • getAbsoluteMaxAlignment

        int getAbsoluteMaxAlignment()
        Gets the maximum alignment value that is allowed by this data organization. When getting an alignment for any data type it will not exceed this value. If NO_MAXIMUM_ALIGNMENT is returned, the data organization isn't specifically limited.
        Returns:
        the absolute maximum alignment or NO_MAXIMUM_ALIGNMENT
      • getMachineAlignment

        int getMachineAlignment()
        Gets the maximum useful alignment for the target machine
        Returns:
        the machine alignment
      • getDefaultAlignment

        int getDefaultAlignment()
        Gets the default alignment to be used for any data type that isn't a structure, union, array, pointer, type definition, and whose size isn't in the size/alignment map.
        Returns:
        the default alignment to be used if no other alignment can be determined for a data type.
      • getDefaultPointerAlignment

        int getDefaultPointerAlignment()
        Gets the default alignment to be used for a pointer that doesn't have size.
        Returns:
        the default alignment for a pointer
      • getSizeAlignment

        int getSizeAlignment​(int size)
                      throws NoValueException
        Gets the alignment that is defined for a data type of the indicated size if one is defined.
        Parameters:
        size - the size of the data type
        Returns:
        the alignment of the data type.
        Throws:
        NoValueException - if there isn't an alignment defined for the indicated size.
      • getBitFieldPacking

        BitFieldPacking getBitFieldPacking()
        Get the composite bitfield packing information associated with this data organization.
        Returns:
        composite bitfield packing information
      • getSizeAlignmentCount

        int getSizeAlignmentCount()
        Gets the number of sizes that have an alignment specified.
        Returns:
        the number of sizes with an alignment mapped to them.
      • getSizes

        int[] getSizes()
        Gets the sizes that have an alignment specified.
        Returns:
        the sizes with alignments mapped to them.
      • getIntegerCTypeApproximation

        java.lang.String getIntegerCTypeApproximation​(int size,
                                                      boolean signed)
        Returns the best fitting integer C-type whose size is less-than-or-equal to the specified size. "long long" will be returned for any size larger than "long long";
        Parameters:
        size - integer size
        signed - if false the unsigned modifier will be prepended.
        Returns:
        the best fitting
      • getAlignment

        int getAlignment​(DataType dataType)
        Determines the alignment value for the indicated data type. (i.e. how the data type gets aligned within other data types.) NOTE: this method should not be used for bitfields which are highly dependent upon packing for a composite. This method will always return 1 for Dynamic and FactoryDataTypes.
        Parameters:
        dataType - the data type
        Returns:
        the datatype alignment
