Error description
Users want as fast performance as possible. Recent studies have shown possible areas of improvements in data transformation which involve - less overhead in range checks using static values - faster construction of BigDecimals and BigIntegers Improve the performance of Records and DataBindings which are targeting COBOL, C and PL/I applications. These applications may be CICS, IMS or Batch applications. They may also involve Messaging or File based applications that are exchanging COBOL data. BPM release requriement: Z - Improve performance of COBOL, C, PL/1 DataBindings (52992) Code changes ------------------ In the marshall library: Use the six pre-defined BigDecimal and BigInteger constants instead of creating new objects: lowerRange_ = new BigDecimal("0"); changes to lowerRange_ = BigDecimal.ZERO; Applies for all the following values: BigDecimal.ZERO BigDecimal.ONE BigDecimal.TEN BigInteger.ZERO BigInteger.ONE BigInteger.TEN Use the "integer" constructors of the BigDecimal class instead of the String constructor when creating known constant values: BigDecimal two = new BigDecimal("2"); BigDecimal one = new BigDecimal("1"); BigDecimal pointFive = new BigDecimal("0.5"); changes to BigDecimal two = new BigDecimal(2); BigDecimal one = BigDecimal.ONE; BigDecimal pointFive = new BigDecimal(5).movePointLeft (1); Use the BigDecimal integral constructor when creating a BigInteger from an integer value instead of the String constructor: int exponentBase = 16; BigInteger biExponent = new BigInteger(Integer.toString(exponentBase)); changes to int exponentBase = 16; BigInteger biExponent = new BigDecimal(exponentBase).toBigInteger(); Use the "integer" constructors of the BigDecimal class instead of the String constructor when data type is an integer type: result = new BigDecimal(Byte.toString(byteResult)); result = new BigDecimal(Short.toString(shortResult)); result = new BigDecimal(Short.toString(shortResult)); result = new BigDecimal(Integer.toString(intResult)); result = new BigDecimal(Integer.toString(intResult)); result = new BigDecimal(Long.toString(longResult)); changes to result = new BigDecimal(byteResult); result = new BigDecimal(shortResult); result = new BigDecimal(shortResult); result = new BigDecimal(intResult); result = new BigDecimal(intResult); result = new BigDecimal(longResult);
