Constructor Details

ReadTable

public ReadTable()

Method Details

setInitialColonIsKeyword

public void setInitialColonIsKeyword(boolean whenInitial)

Set whether ":IDENTIFIER" should be treated as a keyword.

setFinalColonIsKeyword

public void setFinalColonIsKeyword(boolean whenFinal)

Set whether "IDENTIFIER:" should be treated as a keyword.

initialize

public void initialize(boolean sharpIsTerminating)

createInitial

public static ReadTable createInitial()

Create a new ReadTable and initialize it appropriately for Common Lisp.

setBracketMode

public void setBracketMode(int mode)

Specify how '[' and ']' (and '<') are handled. The value -2 means [a b c] is ($bracket-list$ a b c) and f[a b] is ($bracket-apply$ f a b). The value -1 means that '[' and ']' are plain token constituents. The value 0 means that '[' and ']' are equivalent to '(' and ')'. The value 1 means that '[' and ']' are equivalent to '(' and ')', except within a token starting with '<', in which case they are constituents. This is so '[' is non-terminating when reading say '<char[]>'

setBracketMode

public void setBracketMode()

Specify how '[' and ']' are handled. Unless overridden, uses defaultBracketMode.

putReaderCtor

public void putReaderCtor(String key,
 Procedure proc)

Add a mapping for a SRFI-10 constructor tag.

putReaderCtor

public void putReaderCtor(String key,
 Type type)

Add a mapping for a SRFI-10 constructor tag.

putReaderCtorFld

public void putReaderCtorFld(String key,
 String cname,
 String fname)

Map a SRFI-10 constructor tag to Procedure-valued lazy field

getReaderCtor

public Object getReaderCtor(String key)

Resolve a SRFI-10 constructor tags to a functions.

getCurrent

public static ReadTable getCurrent()

setCurrent

public static void setCurrent(ReadTable rt)

lookup

public ReadTableEntry lookup(int ch)

makeSymbol

protected Object makeSymbol(String name)
