Constructor Detail

SignatureKey

public SignatureKey(Method method)

Creates a SignatureKey from the method.

Parameters:

method - The method from which to create the signature

SignatureKey

public SignatureKey(String name,
                    Class<?>... parameterTypes)

Creates a SignatureKey from the given name and parameter types.

Parameters:

name - The method name

parameterTypes - The method parameter types

Method Detail

methodComparator

public static Comparator<Method> methodComparator()

Returns a Comparator that compares two methods on the basis of their signatures.

Returns:

The method comparator

getName

public String getName()

Gets the method name.

Returns:

The method name

getParameterTypes

public Class<?>[] getParameterTypes()

Gets the parameter types to the method.

Returns:

The parameter types

equals

public boolean equals(Object o)

Equality of method signatures is done strictly on method name and parameter types.

Overrides:

equals in class Object

Parameters:

o - The object to compare for equality

Returns:

True if equal

hashCode

public int hashCode()

Returns the hash code.

Overrides:

hashCode in class Object

Returns:

The hash code

compareTo

public int compareTo(SignatureKey other)

Compares two signatures on method name, number of parameters, and finally the parameter types themselves.

Specified by:

compareTo in interface Comparable<SignatureKey>

Parameters:

other - The other signature

Returns:

0 if equal, negative int if this is less than other, positive int if otherwise
