Method Detail

candidates

protected java.util.List<MatchMetrics> candidates(java.lang.String name,
                                                  int num,
                                                  int access,
                                                  boolean isStatic,
                                                  boolean internal,
                                                  boolean first,
                                                  java.util.Set<SignatureKey> exist)

Get the list of all possible methods that could match in this class AND its parent classes. The actual types are not checked but the method name, access mode, static/instance and number of parameters must all match.

Specified by:

candidates in class FuzzyMethodLookup

Parameters:

name - Method name.

num - Number of parameters.

access - Access mode (KW_PUBLIC, KW_PROTECTD or KW_PRIVATE).

isStatic - If true, only static methods will be looked up. Otherwise any method can be returned.

internal - true if the lookup is internal to the current class definition.

first - true if the first match should be immediately returned as the result.

exist - The set of existing methods already represented in the list.

Returns:

List of possible methods that match. This may be an empty list if no match exists.

isImplemented

protected boolean isImplemented(java.lang.String caller,
                                java.lang.String callee)

Detect if the callee class is an instance of an implemented interface of the caller class.

Specified by:

isImplemented in class FuzzyMethodLookup

Parameters:

caller - The caller type.

callee - The callee type.

Returns:

true if the given class is an implemented interface in this class.

isInheritedFrom

protected boolean isInheritedFrom(java.lang.String caller,
                                  java.lang.String callee,
                                  java.lang.Runnable incrementer)

Detect if the callee class is an instance of a parent class or an implemented interface of a parent class, of the caller.

Specified by:

isInheritedFrom in class FuzzyMethodLookup

Parameters:

caller - The caller type.

callee - The callee type to check.

incrementer - Code to be executed to increment the inheritance level.

Returns:

true if the given class is a parent class or an implemented interface of a parent class.

isSetParam

protected boolean isSetParam(java.lang.String method)

Reports if the class name is Progress.Lang.ParameterList and the method name is setParameter().

Specified by:

isSetParam in class FuzzyMethodLookup

Parameters:

method - The method name.

Returns:

true if this is a setParameter call.

getClassName

protected java.lang.String getClassName()

Get the class name where this method lookup starts from.

Specified by:

getClassName in class FuzzyMethodLookup

Returns:

See above.

parseObjectSpec

private ClassDefinition parseObjectSpec(java.lang.String spec)

Parse the given object spec (in the form "object" or "jobject") and return the class definition associated with _CLS_.

Parameters:

spec - The specification to parse.

Returns:

The class definition or null if the spec was malformed or if there is no such definition.
