Detailed Description

Instances of this class hold and perform operations on the BinX XML Schema type <integer-32>. The class provides manipulations such as:

• Serializing an integer value to a file stream
• Parsing and storing a single integer value from a string

The BinX primitive data type 32-bit signed integer is treated in accordance with the XSD definition of this data type. Hence, an instance of this class must have a value from -(2**31) to (2**31 - 1).
Since: BinX version 1.0.

Constructor & Destructor Documentation

BxInteger32::BxInteger32 (   )

Default constructor. Constructs and initialises an instance of the class BxInteger32. Default attribute values are assigned as follows: sizeInBits_ = 32; sizeInBytes_ = 4; sizeInAll_ = 4;

BxInteger32::BxInteger32 (  const BxInteger32 &  copy  )

Construct a BxInteger32 instance by copying a specified BxInteger32 instance. Constructs and initialises an instance of the class BxInteger32. Parameters: copy  A reference to the BxInteger32 instance to copy.

BxInteger32::BxInteger32 (  const bx_int32  i  )

Construct a BxInteger32 instance and assign it a specified 32-bit signed integer value. Constructs and initialises an instance of the class BxInteger32. Parameters: i  A 32-bit integer value to initialise the new BxInteger32 object.

bool BxInteger32::equals (  const BxDataObject &  dataObj  )  const [virtual]

Compares the value of a specified data object with the value of this object. In this method, two objects are considered to be equal if they are of the same BinX object type and if they store the same data value. Also, only primitive BinX data types implement this method. Note: Byte order differences are not compensated for in this test. Hence, two signed 32-bit integers that are equal in value, but represented in different byte orders would be found to be unequal. Parameters: dataObj  A reference to another data object to be compared with this object. Returns: true If the data type and value of the two objects are equal, false If the objects differ in type or value. Reimplemented from BxDataObject.

BxInteger32 & BxInteger32::operator= (  const bx_int32  i  )

Overloaded operator = assigns a 32-bit signed integer from a specified source to a BxInteger32 destination object. Parameters: i  A 32-bit signed integer value to be assigned to a BxInteger32 object. Returns: A reference to this BxInteger32 object after the assignment has been performed.

bool BxInteger32::parseValue (  const char *  strVal  )  [virtual]

Extract a 32-bit signed integer value from a specified string and assign the value to this object. The data contained in the input string is assumed to be in ASCII representation, and to contain an integer represented in decimal or hexadecimal (i.e., base 10 or base 16). A hexademinal string must begin with the characters 0x. The input string must not contain commas, periods, or other symbols. The input string must be null-terminated. All bytes of the input string are used in the conversion process. The input bytes are converted to integer representation, in conformance with the definiton of a BxInteger32 object value. The converted value is stored as the value of this object. Only primitive BinX data types implement this method. Parameters: strVal  A pointer to an ASCII string containing an integer value. Returns: true If value conversion was successful, false If the input string is NULL. Reimplemented from BxDataObject.

char * BxInteger32::toString (  bool  xml  )  [virtual]

Return a string containing the DataBinX XML element (or printable value only ) for the value of this BxInteger32 object. The DataBinx representation of a BxInteger32 object value consists of: The BinX XML tags, <integer-32> and </integer-32> The binary data value of this object, converted to a printable representation Example Return Result: <integer-32>-74982</integer-32> This method allocates memory to hold the returned string. The caller is responsible for releasing the memory when the string is no longer needed. If the BinX XML tags are not required, then the input boolean flag can be used to request that only the converted binary data value be included in the result string. Only BinX primitive data types implement this method. Parameters: xml  A boolean indicating whether to include BinX XML tags or not. Returns: A string buffer containing the DataBinX representation of the value of this object, if the input flag is true, A string buffer containing the printable representation of the value of this object, if the input flag is false. Reimplemented from BxDataObject.
