isIdentifierKeyword

public static boolean isIdentifierKeyword(CharSequence text)

Determines whether the given text matches one of the Ion identifier keywords null, true, or false.

This does not check for non-identifier keywords such as null.int.

Parameters:

text - the symbol to check.

Returns:

true if the text is an identifier keyword.

symbolNeedsQuoting

public static boolean symbolNeedsQuoting(CharSequence symbol,
 boolean quoteOperators)

Determines whether the text of a symbol requires (single) quotes.

Parameters:

symbol - must be a non-empty string.

quoteOperators - indicates whether the caller wants operators to be quoted; if true then operator symbols like != will return true. has looser quoting requirements than other containers.

Returns:

true if the given symbol requires quoting.

Throws:

NullPointerException - if symbol is null.

printSymbol
