Detailed Description

Context Manager.

The Context manager is reponsible for changing and restoring the context of tokens.

Constructor & Destructor Documentation

def core.tokenizer.ContextManager.__init__	(		self,
			tokenizer
	)

Stores the contexts that have already been created.

This is needed incase multiple tokens need to be sent to the same context (e.g. function call) Stores the old context and the destination for restoring contexts.

Member Function Documentation

def core.tokenizer.ContextManager.bindMany	(		self,
			token,
			inst,
			dest,
			retInst,
			binds,
			restores
	)

Send a token to a different context.

Create this context first if it does not exist yet. Further tokens from the same source (instruction, context) pair will be sent to the same context.

Parameters

token	The token to change and send.
inst	The instruction that wants to change the token.
dest	The new destination of the token.
retInst	The instance to send the token to when restoring the context.
binds	The amount of tokens that will be bound to the context.
restores	The amount of tokens the context will produce before being deleted.

def core.tokenizer.ContextManager.bind	(		self,
			destInst,
			destPort,
			context,
			restores
	)

Bind a new context to a given context and destination.

When a token with the new context encounters a context restore operation, it will be bound to the old context, and new instruction.

Parameters

destination	The instruction to bind to the context.
port	The port to bind to the context. None if the port should not change.
context	The context to restore.
restores	The amount of tokens the context will produce.

def core.tokenizer.ContextManager.restore	(		self,
			token
	)

Restore a token.

In order to do this, we simply change the destination and context of the token to those found in the restoremap.
