1.156.3 Symbol class: symbol table

hasInterned: aString ifTrue: aBlock
If aString has not been interned yet, answer false. Else, pass the interned version to aBlock and answer true. Note that this works because String>>#hash calculates the same hash value used by the VM when interning strings into the SymbolTable. Changing one of the hashing methods without changing the other will break this method.


isSymbolString: aString
Answer whether aString has already been interned. Note that this works because String>>#hash calculates the same hash value used by the VM when interning strings into the SymbolTable. Changing one of the hashing methods without changing the other will break this method.

calculates

rebuildTable
Rebuild the SymbolTable, thereby garbage-collecting unreferenced Symbols. While this process is done, preemption is disabled because it is not acceptable to leave the SymbolTable in a partially updated state. Note that this works because String>>#hash calculates the same hash value used by the VM when interning strings into the SymbolTable. Changing one of the hashing methods without changing the other will break this method.
