public class CobolDatatypeFactory
extends DatatypeFactory

Concrete implementation of DatatypeFactory with COBOL Field related factory methods.

Instances of this class or its subclasses will automatically construct instances of com.ibm.jzos.fields.daa classes if the com.ibm.jzos.fields.daa package is available at runtime. See DatatypeFactory for more information.

Construct and return a BinaryAsIntField, advancing the current offset by its byte length.

Note that the field behaves as if TRUNC(BIN) was set in COBOL.

Overrides:

getBinaryAsIntField in class DatatypeFactory

Parameters:

precision - the number of decimal digits of precision

signed - true if the value is signed

Returns:

BinaryAsIntField

getBinaryAsBigDecimalField

public BinaryAsBigDecimalField getBinaryAsBigDecimalField(int precision,
                                                          int scale,
                                                          boolean signed)

Construct and return a BinaryAsBigDecimalField, advancing the current offset by its byte length.

Note that the field behaves as if TRUNC(BIN) was set in COBOL.

Overrides:

getBinaryAsBigDecimalField in class DatatypeFactory

Parameters:

precision - the number of decimal digits of precision

scale - the number of implied decimal digits in the fractional part of the field

signed - true if the value is signed

Returns:

BinaryAsBigDecimalField

getBinaryAsBigIntegerField

public BinaryAsBigIntegerField getBinaryAsBigIntegerField(int precision,
                                                          int scale,
                                                          boolean signed)

Construct and return a BinaryAsBigIntegerField, advancing the current offset by its byte length.

Note that the field behaves as if TRUNC(BIN) was set in COBOL.

Overrides:

getBinaryAsBigIntegerField in class DatatypeFactory

Parameters:

precision - the number of decimal digits of precision
