Method Detail

modifiersToString

public static String modifiersToString(int modifiers,
                                       boolean isMethod)

Convert modifiers into a string representation, e.g. "public static final".

Parameters:

modifiers - The field, method or class modifiers.

isMethod - True if this is a method, false if this is a field or class.

Returns:

The modifiers, as a string.

modifiersToString

public static void modifiersToString(int modifiers,
                                     boolean isMethod,
                                     StringBuilder buf)

Convert modifiers into a string representation, e.g. "public static final".

Parameters:

modifiers - The field or method modifiers.

isMethod - True if this is a method, false if this is a field or class.

buf - The buffer to write the result into.

getIdentifierToken

public static boolean getIdentifierToken(Parser parser,
                                         char separator,
                                         char separatorReplace)
                                  throws Parser.ParseException

Parse a Java identifier with the given separator ('.' or '/'). Potentially replaces the separator with a different character. Appends the identifier to the token buffer in the parser.

Parameters:

parser - The parser.

separator - The separator character.

separatorReplace - The character to replace the separator with.

Returns:

true if at least one identifier character was parsed.

Throws:

Parser.ParseException - If the parser ran out of input.

getIdentifierToken

public static boolean getIdentifierToken(Parser parser)
                                  throws Parser.ParseException

Parse a Java identifier part (between separators and other non-alphanumeric characters). Appends the identifier to the token buffer in the parser.

Parameters:

parser - The parser.

Returns:

true if at least one identifier character was parsed.

Throws:

Parser.ParseException - If the parser ran out of input.
