- Enclosing class:
- CachedMethod
public static class CachedMethod.ArrayMapCachedMethod
- extends CachedMethod
A class representing the invocation of a scalar method on
an array of elements.
Method Summary |
Type |
getReturnType()
Override the base class to return an array type with the
element type being the return type of the underlying scalar
method. |
Token |
invoke(java.lang.Object[] argValues)
Invoke the method represented by this CachedMethod. |
boolean |
isValid()
Override the base class to correctly implement the
isValid() method. |

CachedMethod.ArrayMapCachedMethod
public CachedMethod.ArrayMapCachedMethod(java.lang.String methodName,
Type[] argumentTypes,
int type,
CachedMethod cachedMethod,
boolean[] reducedArgs)
throws IllegalActionException
- Constructs a CachedMethod$ArrayMapCachedMethod object.
- Parameters:
methodName
- The name of the method.argumentTypes
- The types of the arguments.type
- An integer specifying the typecachedMethod
- The method to be invokedreducedArgs
- An array of booleans where if an
element of the array is true and the corresponding argument
is an ArrayToken, then invoke() handles those arguments
specially.
- Throws:
IllegalActionException
- Not thrown in this derived
class, but the superclass throws it if the return type of
the cached method cannot be determined.
invoke
public Token invoke(java.lang.Object[] argValues)
throws IllegalActionException
- Invoke the method represented by this CachedMethod. This
implements any conversions necessary to turn token arguments
into other arguments, and to convert the result back into
a token.
- Overrides:
invoke
in class CachedMethod
- Parameters:
argValues
- An array of token objects that will be used
as the arguments. Note that each element must be an
ArrayToken and each ArrayToken must have the same length
as the other ArrayTokens.
- Returns:
- The token result of the method invocation.
- Throws:
IllegalActionException
- If the invoked method
throws it.
isValid
public boolean isValid()
- Override the base class to correctly implement the
isValid() method.
- Overrides:
isValid
in class CachedMethod
- Returns:
- True if a method was found.
getReturnType
public Type getReturnType()
throws IllegalActionException
- Override the base class to return an array type with the
element type being the return type of the underlying scalar
method.
- Overrides:
getReturnType
in class CachedMethod
- Returns:
- An ArrayType with an appropriate element type.
- Throws:
IllegalActionException
- If a method or function with
the correct argument types was not found.
methodDescription
public java.lang.String methodDescription()
- Return an appropriate description of the method being invoked.
- Overrides:
methodDescription
in class CachedMethod
- Returns:
- A description of the method being invoked.
