Field Detail

literalToken

public final short literalToken
Token value.


literalError

public short literalError
Error value.


flag_dw

public boolean flag_dw
Double Word storage. Valid for integer and floating-point.


literalBoolean

public boolean literalBoolean
Boolean value.


literalChar

public char literalChar
Character value. Separated from literalInteger because char is an unsigned integer type.


literalString

public java.lang.String literalString
String value.


literalInteger

public long literalInteger
Sign-extended value for ints and longs. Note that the JLS treats byte and short constants as int constants.


literalFloat

public double literalFloat
Floating-point value. The f2d widening primitive conversion is exact, so we can safely store 1-word floats in 2 words.

Method Detail

scanConstant

public static LexerLiteral scanConstant(FastLexer lexer)
Provide one that accepts a JavaLexer because the LexerToken invocations will be optimized.


scanConstant

public static LexerLiteral scanConstant(LexerToken lexerToken,
                                        ReadTextBuffer textBuffer)

copyConstant

public static LexerLiteral copyConstant(LexerLiteral source)

getConstantValue

public java.lang.Object getConstantValue()

digit2int

public static int digit2int(char ch,
                            int base)
