Constructor Detail

ReadTable

public ReadTable()

Method Detail

initialize

public void initialize()

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 -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 ''

setBracketMode

public void setBracketMode()

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

putReaderCtor

public void putReaderCtor(java.lang.String key,
                          Procedure proc)

Add a mapping for a SRFI-10 constructor tag.

putReaderCtorFld

public void putReaderCtorFld(java.lang.String key,
                             java.lang.String cname,
                             java.lang.String fname)

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

getReaderCtor

public java.lang.Object getReaderCtor(java.lang.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 java.lang.Object makeSymbol(java.lang.String name)
