Detailed Description

The lSystem namespace contains functions to apply L-system rules to sequences of tokens, including matching rules and applying production rules.

Function Documentation

applyCallIds()

void lSystem::applyCallIds	(	std::list< Token > &	outputTokens,
		int &	callCounter )

Applies call IDs to sequences of tokens representing function calls.

Processes the output tokens to assign unique call IDs to sequences representing function calls, ensuring that each unique call sequence has a unique ID.

Parameters

outputTokens	A list of tokens representing the current state of the output.
callCounter	A reference to the counter used for assigning new call IDs.

applyProductionRules()

void lSystem::applyProductionRules	(	std::list< Token > &	outputTokens,
		const std::vector< ProductionRule > &	productionRules )

Applies production rules to the output tokens.

Replaces tokens in the output that match a production rule with the corresponding production, modifying the output sequence accordingly.

Parameters

outputTokens	A list of tokens representing the current state of the output.
productionRules	The vector of production rules to apply to the output.

findEqualCall()

int lSystem::findEqualCall	(	const std::unordered_map< std::vector< Token >, int, TokenVectorHash, TokenVectorEqual > &	callMap,
		const std::vector< Token > &	callTokens )

Finds an existing call ID for a given set of tokens, if one exists.

Checks if a given sequence of tokens has already been assigned a call ID.

Parameters

callMap	A map of token sequences to their corresponding call IDs.
callTokens	The vector of tokens representing the call to check.

Returns

The call ID if found, or -1 if no existing call ID is found.

lSystem()

std::vector< Token > lSystem::lSystem	(	int	iterations,
		const std::vector< ProductionRule > &	productionRules,
		const std::vector< Token > &	inputTokens )

Applies L-system rules to generate a sequence of tokens.

Takes an initial set of tokens, applies the specified production rules for a given number of iterations, and generates a new sequence of tokens based on the rules.

Parameters

iterations	The number of times the production rules should be applied.
productionRules	The production rules to apply, represented as a vector of ProductionRule objects.
inputTokens	The initial vector of Tokens to which the rules are applied.

Returns

A vector of Tokens resulting from applying the production rules to the input.

match()

int lSystem::match	(	std::string	match,
		const std::vector< ProductionRule > &	rules )

Matches a string to a production rule.

Searches for a match between a given string and the rules in the provided vector.

Parameters

match	The string to match against the production rules.
rules	The vector of production rules to search.

Returns

The index of the matching rule, or -1 if no match is found.
