toValue
public java.lang.String toValue(java.lang.String string, INode node)
Description copied from interface:IValueConverter
Creates a value from the given input. The input is conformant to a data type or terminal rule.
The given
string
ornode
may be null but not both of them.- Parameters:
string
- the string that was inferred from the node. Usually the node's text but may be reduced to the parts of the node that are nothidden
.node
- the parsed node including hidden parts.- Returns:
- the new value or
null
.
-
convertFromString
protected java.lang.String convertFromString(java.lang.String literal, INode node) throws ValueConverterWithValueException
Converts a string literal (including leading and trailing single or double quote) to a semantic string value. Recovers from invalid escape sequences and announces the first problem with aValueConverterWithValueException
.- Throws:
ValueConverterWithValueException
- if the given string is syntactically invalid.- Since:
- 2.7
