buildLHSFieldValue

public abstract void buildLHSFieldValue(StringBuilder buf,
                                        int constraintType,
                                        String fieldType,
                                        String fieldValue)

Concatenate a String to the provided buffer suitable for the fieldValue and fieldType. Strings and Dates are escaped with double-quotes, whilst Numerics, Booleans, (Java 1.5+) enums and all other fieldTypes are not escaped at all. Guvnor-type enums are really a pick list of Strings and in these cases the underlying fieldType is a String.

Parameters:

buf -

constraintType -

fieldType -

fieldValue -

buildRHSFieldValue

public abstract void buildRHSFieldValue(StringBuilder buf,
                                        String fieldType,
                                        String fieldValue)

Concatenate a String to the provided buffer suitable for the fieldType and fieldValue. Strings are escaped with double-quotes, Dates are wrapped with a call to a pre-constructed SimpleDateFormatter, whilst Numerics, Booleans, (Java 1.5+) enums and all other fieldTypes are not escaped at all. Guvnor-type enums are really a pick list of Strings and in these cases the underlying fieldType is a String.

Parameters:

buf -

fieldType -

fieldValue -
