org.apache.hivemind.methodmatch.MethodMatcher
- public class MethodMatcher
- extends java.lang.Object
A utility class used for matching a org.apache.hivemind.service.MethodSignature against a
method pattern (this is primarily used by interceptor factories). A method pattern consists of a name pattern and an optional
parameters pattern.
The name pattern matches against the method name, and can be one of the following:
- A single name - which requires an exact match. Example:
perform
- A name suffix, indicated with a leading '*'. Example:
*form
- A name prefix, indicated with a trailing '*'. Example:
per*
- A name substring, indicated with leading and trailing '*'s. Example:
*erfo*.
- A match any, indicated with a single '*'. Example:
*
The parameters pattern follows the name pattern and is optional. It is used to check the number
of parameters, or their types. When the parameters pattern is omitted, then the number and types
of parameters are not considred when matching methods.
The parameters pattern, when present, is contained within open and closed parenthis after the
method pattern. Inside the parenthesis may be a number, indicating the exact number of method
parameters to match against. Alternately, a comma-seperated list of Java types is used, which
matches against a method that takes the exact set of parameters. Examples:
perform()-- method with no parameters
perform(2)-- method with two parameters
perform(java.util.List, int)- method taking a List and an int parameter

- Constructor that takes a default value returned when no stored method pattern matches the
input to

put
public void put(java.lang.String methodPattern,
java.lang.Object patternValue)
- Stores a pattern and an associated value. Values can later be accessed via
get(MethodSignature) 55 .
get
public java.lang.Object get(org.apache.hivemind.service.MethodSignature sig)
- Returns a pattern value prevoiusly stored via
put(String, Object) 55 . Iterates over
the patterns stored, in the order in which they were stored, until a match is found.
