Method Summary

static java.lang.String	convert(char c) Returns a symbolic name for passed symbol, e.g.
static java.lang.String	makeIdentifier(java.lang.String symbol) Converts the passed character sequence (symbol) to a name that can be used as identifier (but not as Java identifier).
static java.lang.String	makeIdentifier(java.lang.String symbol, boolean startIsSignificant) Converts the passed character sequence (symbol) to a name that can be used as identifier, optionally as Java identifier.
static java.lang.String	makeIdentifier(java.lang.String symbol, java.lang.String enclosingQuoteSubstitute) Converts the passed character sequence (symbol) to a name that can be used as identifier (but not as Java identifier).
static java.lang.String	makeIdentifier(java.lang.String symbol, java.lang.String enclosingQuoteSubstitute, boolean startIsSignificant) Converts the passed character sequence (symbol) to a name that can be used as identifier, optionally as Java identifier.

Method Detail

makeIdentifier

public static java.lang.String makeIdentifier(java.lang.String symbol)

Converts the passed character sequence (symbol) to a name that can be used as identifier (but not as Java identifier). If enclosing quotes are found, they will be substituted by "_".

Parameters:

symbol - character sequence to be converted to identifier

makeIdentifier

public static java.lang.String makeIdentifier(java.lang.String symbol,
                                              boolean startIsSignificant)

Converts the passed character sequence (symbol) to a name that can be used as identifier, optionally as Java identifier. If enclosing quotes are found, they will be substituted by "_".

Parameters:

symbol - character sequence to be converted to identifier

startIsSignificant - when true a Java identifier is produced

makeIdentifier

public static java.lang.String makeIdentifier(java.lang.String symbol,
                                              java.lang.String enclosingQuoteSubstitute)

Converts the passed character sequence (symbol) to a name that can be used as identifier (but not as Java identifier). If enclosing quotes are found, they will be substituted by passed substitute string.

Parameters:

symbol - character sequence to be converted to identifier

enclosingQuoteSubstitute - the string to be used for enclosing quotes

makeIdentifier

public static java.lang.String makeIdentifier(java.lang.String symbol,
                                              java.lang.String enclosingQuoteSubstitute,
                                              boolean startIsSignificant)

Converts the passed character sequence (symbol) to a name that can be used as identifier, optionally as Java identifier. If enclosing quotes are found, they will be substituted by passed substitute string.

Parameters:

symbol - character sequence to be converted to identifier

enclosingQuoteSubstitute - the string to be used for enclosing quotes

startIsSignificant - when true a Java identifier is produced

convert

public static java.lang.String convert(char c)

Returns a symbolic name for passed symbol, e.g. "lparen" for "(".
