`class DependencyNode`

Represents a build graph node for resolving and building a single dependency.

Definitions

`def initialize(chain, dependency, environment, arguments)`

Initialize the dependency node.

Signature

parameter　chain　Build::Dependency::Chain: The dependency chain.
parameter　dependency　Build::Dependency: The dependency to resolve.
parameter　environment　Build::Environment: The root environment.
parameter　arguments　Array: Arguments passed down the build chain.

Implementation

def initialize(chain, dependency, environment, arguments)
	@chain = chain
	@dependency = dependency
	@environment = environment
	@arguments = arguments
	
	# Wait here, for all dependent targets, to be done:
	super(Files::List::NONE, :inherit)
end

`def ==(other)`

Signature

returns　Boolean: Whether this node is equal to another.

Implementation

def == other
	super and
		@chain == other.chain and
		@dependency == other.dependency and
		@environment == other.environment and
		@arguments == other.arguments
end

`def hash`

Signature

returns　Integer: A hash value for this node.

Implementation

def hash
	super ^ @chain.hash ^ @dependency.hash ^ @environment.hash ^ @arguments.hash
end

`def task_class(parent_task)`

Signature

returns　Class: The task class to use for this node.

Implementation

def task_class(parent_task)
	DependencyTask
end

`def name`

Signature

returns　String: The name of the dependency.

Implementation

def name
	@dependency.name
end

`def provisions`

Signature

returns　Array: The provisions resolved for this dependency.

Implementation

def provisions
	@chain.resolved[@dependency]
end

`def public?`

Signature

returns　Boolean: Whether this dependency is public.

Implementation

def public?
	@dependency.public?
end

`def provision_node_for(provision)`

Build a class Build::ProvisionNode for the given provision.

Signature

parameter　provision　Build::Dependency::Provision: The provision to wrap.
returns　Build::ProvisionNode: The corresponding provision node.

Implementation

def provision_node_for(provision)
	ProvisionNode.new(@chain, provision, @environment, @arguments)
end
