Method Detail

pushNodeVariableName

public void pushNodeVariableName(String jjtThis)

popNodeVariableName

public void popNodeVariableName()

toHexString

public String toHexString(int i)

toHexStringL

public String toHexStringL(long l)

toOctalString

public String toOctalString(int i)

lastPart

public String lastPart(String source,
                       int delimiter)

nodeIsInterface

public boolean nodeIsInterface(String nodeName)

addEscapes

public String addEscapes(String input)

bitSetToLongArray

public long[] bitSetToLongArray(BitSet bs,
                                int numLongs)

codePointAsString

public String codePointAsString(int ch)

isBitSet

public boolean isBitSet(long num,
                        int bit)

firstCharAsInt

public int firstCharAsInt(String s)

powerOfTwoInHex

public String powerOfTwoInHex(int i)

getID

public String getID(String name)

getPreprocessorSymbol

public String getPreprocessorSymbol(String key,
                                    String defaultValue)

displayChar

public String displayChar(int ch)

Parameters:

ch - the code point. If it is not ASCII, we just display the integer in hex.

Returns:

a String to use in generated Java code. Rather than display the integer 97, we display 'a', for example.

displayChars

public String displayChars(int[] char_array)

This method is only here to help with debugging NFA state-related logic in templates. Sometimes, you want to see ASCII rather than code points.

Parameters:

char_array - a list of code points.

Returns:

a String to use in generated template code.

public Map<String,Object> tokenSubClassInfo()

translateIdentifier

public String translateIdentifier(String ident)

startProduction
