Detailed Description

The symtab class is used to represent a symbol table. The indexes are strings, the data may be arbitrary pointers. Access times are O(1).

Constructor & Destructor Documentation

symtab::~symtab ( ) [virtual]

The destructor.

Definition at line 27 of file

The default constructor.

Definition at line 45 of file

symtab::symtab ( const symtab ) [private]

The copy constructor. Do not use.

Member Function Documentation

void symtab::assign ( const rcstring name,
void *  value 

The assign method is used to assign a value to a given variable.

Definition at line 143 of file

void symtab::dump ( const char *  caption) const

The dump method is used to dump the contents of the symbol table. The caption will be used to indicate why the symbol table was dumped.

Definition at line 199 of file

The keys method is used to get a list of the keys in the symbol table. This in turn may be used to iterate across all of the values in the symbol table.

Definition at line 229 of file

symtab& symtab::operator= ( const symtab ) [private]

The assignment operator. Do not use.

void * symtab::query ( const rcstring name) const

The query method is used to reference a variable.

If the variable has been defined, the function returns a non-zero value and the value is returned through the 'value' pointer. If the variable has not been defined, it returns zero, and 'value' is unaltered.

void symtab::remove ( const rcstring name)

Definition at line 172 of file

void symtab::set_reaper ( void(*)(void *)  fp)

The set_reaper method is used to set the reaper function to be used when destroying data. The default is to do nothing.

Definition at line 241 of file

void symtab::split ( void  ) [private]

The split method is used to split symbols in the bucket indicated by the split point. The symbols are split between that bucket and the one after the current end of the table.
