public final class MultiFnWoutHierarchy
extends clojure.lang.AFn
implements MultiFn

An implementation of MultiFn that optimizes for pure Class-based method definition and lookup.

Semantic changes:

1. Only Class and Signature are accepted as dispatch values.
2. Make MultiFn.preferMethod(Object,Object) transitive:
   I believe f.preferMethod(a,b) and f.preferMethod(b,c) should imply f.preferMethod(a,c), but that's not not true in clojure.lang.MultiFn.prefers(x,y).
3. The logic in clojure.lang.MultiFn.prefers(x,y) appears to imply that f.preferMethod(x,ancestorOfY) implies f.preferMethod(x,y). This is not what I would expect.
4. clojure.lang.MultFn.prefers() ignores the multimethod's hierarchy, so behavior is different between multimethods that use global-hierarchy vs local. Changed to explicitly use the local hierarchy in preference evaluation. See CLJ-2234.

Performance changes:.

1. Replace persistent data structures with simple unmodifiable HashMaps, etc., requiring some discipline to use mutable objects as immutable. Eventually, should replace with minimal immutable version.
2. Only classes and signatures as a dispatch values.
3. No hierarchy or default dispatch value.

MultiFnWoutHierarchy

public MultiFnWoutHierarchy(java.lang.String n,
                            clojure.lang.IFn dispatchF)

Method Detail

isLegalDispatchValue

public final boolean isLegalDispatchValue(java.lang.Object x)

Description copied from interface: MultiFn

Is x a legal dispatch value for this MultiFn?

For performance reasons, some implementations of MultiFn may restrict kinds of dispatch values they support.

Note: 'Legal' means it is possible to define methods for x, not that one has already been defined.

Specified by:

isLegalDispatchValue in interface MultiFn

getMethodTable

public final clojure.lang.IPersistentMap getMethodTable()

Description copied from interface: MultiFn

Return the table of defined methods, a map from dispatch values to functions.

Specified by:

getMethodTable in interface MultiFn

Returns:

an instance of clojure.lang.IPersistentMap

getPreferTable

public final clojure.lang.IPersistentMap getPreferTable()

Description copied from interface: MultiFn

Return the table of explicit method preferences, a map from dispatch value to set of dispatch values, with the interpretation a method defined for the key dispatch value is preferred to methods defined for any of the dispatch values in the set.

Specified by:

getPreferTable in interface MultiFn

Returns:

an instance of clojure.lang.IPersistentMap

reset

public final MultiFn reset()

Description copied from interface: MultiFn

Clear the MultiFn, removing all defined methods and preferences, and emptying the cache.

Specified by:

reset in interface MultiFn

Returns:

the modified MultiFn.

addMethod

public final MultiFn addMethod(java.lang.Object x,
                               clojure.lang.IFn method)

Specified by:

addMethod in interface MultiFn

Returns:

the modified MultiFn.

removeMethod

public final MultiFn removeMethod(java.lang.Object x)

Description copied from interface: MultiFn

Removes the defined method for dispatch value x, if there is one. If not, does nothing.

Specified by:

removeMethod in interface MultiFn

Returns:

the modified MultiFn.

preferMethod

public final MultiFn preferMethod(java.lang.Object x,
                                  java.lang.Object y)

public final boolean isA(java.lang.Object child,
                         java.lang.Object parent)

Description copied from interface: MultiFn

Specified by:

isA in interface MultiFn

dominates
