Method Detail

convertMethodToFunction

TypeI convertMethodToFunction()

Creates a new function type B based on the original function type A. Takes the receiver type (this type) of A and makes it the first argument of B; B has no receiver type. Used by the DevirtualizePrototypeMethods pass.

hasInstanceType

boolean hasInstanceType()

Returns whether this type represents a constructor.

getInstanceType

ObjectTypeI getInstanceType()

Returns a type representing an instance of this constructor, or null if this is not a constructor.

getReturnType

TypeI getReturnType()

getReferenceName

String getReferenceName()

For a constructor function, returns the name of the instances. For other functions, returns null.

getSource

Node getSource()

Gets the AST Node where this function was defined.

getSubTypes

Iterable<FunctionTypeI> getSubTypes()

Returns an iterable of direct types that are subtypes of this type. This is only valid for constructors and interfaces, and will not be null. This allows a downward traversal of the subtype graph.

getTypeOfThis

TypeI getTypeOfThis()

Gets the type of this in this function.

hasProperties

boolean hasProperties()

setSource

void setSource(Node n)

acceptsArguments

boolean acceptsArguments(List<? extends TypeI> argumentTypes)

Checks if a call to this function with the given list of arguments is valid.

getAncestorInterfaces

Collection<ObjectTypeI> getAncestorInterfaces()

getPrototypeProperty

ObjectTypeI getPrototypeProperty()

getParameterTypes

Iterable<TypeI> getParameterTypes()

getMinArity

int getMinArity()

Returns the number of required arguments.

getMaxArity

int getMaxArity()

Returns the maximum number of allowed arguments, or Integer.MAX_VALUE if variadic.

getTypeParameters

Collection<String> getTypeParameters()

Returns the names of all type parameters.
