convertZoned

protected java.math.BigDecimal convertZoned(byte[] value,
                                            int precision,
                                            int scale,
                                            com.bea.wlxt.mfl.MFLField mflField)
                                     throws BintypeException

Convert a zoned decimal number to a BigDecimal. This will produce a BigDecimal that contains the proper value for the mainframe zoned data given in buf. The zoned decimal paramters relate to COBOL picture strings as follows:

 999v99   5,2,0   Normal case, 5 digits, 2 digits to right of decimal point, no scaling.
 vpp999   5,5,2   5 digits, 3 digits to right of decimal, 2 scale digits.
 999ppv   5,0,2   5 digits, 0 digits to right of decimal, 2 scale digits.
 

Parameters:

buf - The mainframe bytes to be converted.

precision - The number of digits to the right of the decimal point.

scale - The number of assumed zero digits.

write

public void write(BintypeOutputStream byteStream,
                  com.bea.wlxt.mfl.MFLField mflField,
                  java.lang.String value)
           throws BintypeException

Overrides:

write in class Bintype

writeZoned

public void writeZoned(java.io.OutputStream byteStream,
                       java.math.BigDecimal value,
                       int length,
                       int precision,
                       int scale,
                       com.bea.wlxt.mfl.MFLField mflField)
                throws BintypeException

Write a BigDecimal as a mainframe signed zoned decimal number.

writeUnsignedZoned

public void writeUnsignedZoned(java.io.OutputStream byteStream,
                               java.math.BigDecimal value,
                               int length,
                               int precision,
                               int scale,
                               com.bea.wlxt.mfl.MFLField mflField)
                        throws BintypeException

Write a BigDecimal as a mainframe unsigned zoned decimal number.

convertZoned

protected byte[] convertZoned(java.math.BigDecimal value,
                              int length,
                              int precision,
                              int scale,
                              char sign,
                              com.bea.wlxt.mfl.MFLField mflField)
                       throws BintypeException

Convert a BigDecimal to a zoned decimal number. This will produce a byte[] that contains the zoned representation of the given BigDecimal. The zoned decimal paramters relate to COBOL picture strings as follows:

 999v99   5,2,0   Normal case, 5 digits, 2 digits to right of decimal point, no scaling.
 vpp999   5,5,2   5 digits, 3 digits to right of decimal, 2 scale digits.
 999ppv   5,0,2   5 digits, 0 digits to right of decimal, 2 scale digits.
 

Parameters:

value - The value to be written.

length - The size of the returned byte array.

precision - The number of digits to the right of the decimal point.

scale - The number of assumed zero digits.

sign - The sign (+ or -) to place on the result.

Throws:

BintypeException - If value will not fit into the specified zoned number.

isZoned

public boolean isZoned(com.bea.wlxt.mfl.MFLField mflField)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
