 gnu.mapping.Procedure
gnu.mapping.ProcedureN
gnu.mapping.MethodProc
All known Subclasses: gnu.expr.PrimProcedure, gnu.expr.GenericProc, gnu.mapping.CpsProcedure,
| MethodProc | | abstract public class MethodProc extends ProcedureN (Code) | | Similar to a CLOS method.
Can check if arguments "match" before committing to calling method.
|
| Field Summary | |
| final public static int | NO_MATCH
Return code from match: Unspecified failure. | | final public static int | NO_MATCH_AMBIGUOUS
Return code from match: Ambigious which method to select. | | final public static int | NO_MATCH_BAD_TYPE
Return code from match: Invalid argument type.
In that case the lower half is the 0-origin index of the first
argument that does not match. | | final public static int | NO_MATCH_TOO_FEW_ARGS
Return code from match: Too few actual arguments.
The lower half is the minimum number of arguments (if not 0xffff). | | final public static int | NO_MATCH_TOO_MANY_ARGS
Return code from match: Too many actual arguments.
The lower half is the maximum number of arguments (if not 0xffff). | | protected Object | argTypes
The parameter types.
Usually either an Type[] or a String encoding. | | final static Type[] | unknownArgTypes
|
| NO_MATCH | | final public static int NO_MATCH(Code) | | Return code from match: Unspecified failure.
|
| NO_MATCH_AMBIGUOUS | | final public static int NO_MATCH_AMBIGUOUS(Code) | | Return code from match: Ambigious which method to select.
|
| NO_MATCH_BAD_TYPE | | final public static int NO_MATCH_BAD_TYPE(Code) | | Return code from match: Invalid argument type.
In that case the lower half is the 0-origin index of the first
argument that does not match.
|
| NO_MATCH_TOO_FEW_ARGS | | final public static int NO_MATCH_TOO_FEW_ARGS(Code) | | Return code from match: Too few actual arguments.
The lower half is the minimum number of arguments (if not 0xffff).
|
| NO_MATCH_TOO_MANY_ARGS | | final public static int NO_MATCH_TOO_MANY_ARGS(Code) | | Return code from match: Too many actual arguments.
The lower half is the maximum number of arguments (if not 0xffff).
|
| argTypes | | protected Object argTypes(Code) | | The parameter types.
Usually either an Type[] or a String encoding.
|
| unknownArgTypes | | final static Type[] unknownArgTypes(Code) | | |
| getParameterType | | public Type getParameterType(int index)(Code) | | |
| isApplicable | | public int isApplicable(Type[] argTypes)(Code) | | Test if method is applicable to an invocation with given arguments.
Returns -1 if no; 1 if yes; 0 if need to check at run-time.
|
| match | | abstract public int match(CallContext ctx, Object[] args)(Code) | | Match the incoming arguments.
Parameters:
ctx - where to save the matched result on success
Parameters:
args - the incoming argument list non-negative if the match succeeded, else negative |
| mostSpecific | | public static int mostSpecific(MethodProc[] procs, int length)(Code) | | Return the index of the most specific method.
|
| numParameters | | public int numParameters()(Code) | | Return number of parameters, including optional and rest arguments.
|
| resolveParameterTypes | | protected void resolveParameterTypes()(Code) | | Figure out or decode the parameter types, setting argTypes.
