Constructor Detail

NumericFieldDesc

public NumericFieldDesc(java.lang.String fieldName)

Constructor taking a field name.

Parameters:

fieldName - the field name for this descriptor

NumericFieldDesc

public NumericFieldDesc(java.lang.String fieldName,
                int min,
                int max)

Constructor taking a field name and a range.

Parameters:

fieldName - the field name for this descriptor

min - the minimum value

max - the maximum value

Method Detail

isLenient

public boolean isLenient()

Check whether this field descriptor uses lenient parsing

Returns:

true if the parser is lenient, false otherwise.

parse

public java.lang.Integer parse(java.lang.String stringVal)
                        throws java.text.ParseException

Parse the value into the format for this field description. The NumericFieldDescriptor tries parsing using the Integer class, a CardinalNumberFormat, and a MixedNumberFormat.

Overrides:

parse in class IntFieldDesc

Parameters:

stringVal - the value to parse

Returns:

the parsed integer

Throws:

java.text.ParseException - if the string cannot be parsed as an integer

setLenient

public void setLenient(boolean flag)

Set whether this field descriptor enforces strict or lenient parsing. If the lenient flag is not set, then the parsing expects the string arguments to be exact matches for a numeric string. If the flag is set to true, then this parser will match a substring of the argument.

Parameters:

flag -
