All Implemented Interfaces:

Script

public class OverloaderNode

extends MethodNode

Untamed: Wraps a set of JavaMemberNodes with the same message name and arity, and dispatches to the unique one for which the current arguments coerce to its parameter list.

If the current arguments coerce to none or more than one, throw an exception.

make

public static MethodNode make(JavaMemberNode[] nodes)

Enabled:

getDocComment

public String getDocComment()

Enabled:

Specified by:

getDocComment in class MethodNode

getVerb

public String getVerb()

Enabled:

Specified by:

getVerb in class MethodNode

getOptTypedVerb

public String getOptTypedVerb()

Enabled:

Specified by:

getOptTypedVerb in class MethodNode

getArity

public int getArity()

Enabled:

Specified by:

getArity in class MethodNode

addJavaMemberNodesToMap

public void addJavaMemberNodesToMap(FlexMap map)

Enabled: Add all my nodes to the map

Specified by:

addJavaMemberNodesToMap in class MethodNode

shorten

public Script shorten(Object optSelf,
                      String aVerb,
                      Object[] args)

Enabled: Returns the unique matching JavaMemberNode or throw an exception.

Parameters:

optSelf - If present, then a script could shorten using instance-specific data.

aVerb - Must be interned

args - Typically, only its arity is used. But OverloaderNode uses the types of the arguments to select among Java overloads.

Returns:

The Script to use in lieu of this one. Note that it's always correct a Script to just return itself.

execute

                      String aVerb,
                      Object[] args)

Enabled:

                       int priority)
                throws IOException

Enabled:

IOException

toString

public String toString()

Suppressed:

Overrides:
