Method Detail

toEscapedString

protected String toEscapedString(String value)

Overrides:

toEscapedString in class AbstractLexerBasedConverter<String>

toValue

public String toValue(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 or node 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 not hidden.

node - the parsed node including hidden parts.

Returns:

the new value or null.

convertFromString

protected String convertFromString(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 a ValueConverterWithValueException.

Throws:

ValueConverterWithValueException - if the given string is syntactically invalid.
