                    java.lang.Class<R> returnType)
Method Detail

getFunctor

public Generator<R> getFunctor()
Description copied from interface: FunctorRef
Returns the functor to which this refers.

Specified by:
getFunctor in interface FunctorRef<R,Generator<R>>

getReturnType

public java.lang.Class<R> getReturnType()
Description copied from interface: FunctorRef
returns the type of objects that the current functor returns.

Specified by:
getReturnType in interface FunctorRef<R,Generator<R>>

getNumberArgs

public int getNumberArgs()
Description copied from interface: FunctorRef
returns the number of arguments that the current functor requires. Currently, the implementations tend to be hard coded.

Specified by:
getNumberArgs in interface FunctorRef<R,Generator<R>>

getArgType

public java.lang.Class<?> getArgType(int i)
Description copied from interface: FunctorRef
returns the type of the i'th argument to the current functor.

Specified by:
getArgType in interface FunctorRef<R,Generator<R>>

getArgName

public java.lang.String getArgName(int i)
Description copied from interface: FunctorRef
returns the name of the i'th argument to the current functor, as described in the expression being parsed.

Specified by:
getArgName in interface FunctorRef<R,Generator<R>>

isConstant

public boolean isConstant()
Description copied from interface: FunctorRef
Returns TRUE if the underlying functor is a constant generator

Specified by:
isConstant in interface FunctorRef<R,Generator<R>>

isIdentity

public boolean isIdentity()
Description copied from interface: FunctorRef
Returns TRUE if the underlying functor is a unary identity

Specified by:
isIdentity in interface FunctorRef<R,Generator<R>>

toString

public java.lang.String toString()
Overrides:
toString in class java.lang.Object
