Constructor Detail

ParameterSignature

public ParameterSignature()

Create an empty parameter list signature.

ParameterSignature

public ParameterSignature(Method method)

Create a parameter list signature corresponding to the declared parameter list of a Method.

Parameters:

method - The method whose signature will be represented.

ParameterSignature

public ParameterSignature(Constructor<?> constructor)

Create a parameter list signature corresponding to the declared parameter list of a Constructor.

Parameters:

constructor - The constructor whose signature will be represented.

ParameterSignature

public ParameterSignature(Class<?>... parameterTypes)

Create a parameter list signature from an array (or variable argument list) of Class values.

Parameters:

parameterTypes - The sequence of Class objects representing the types of the parameters in this signature.

ParameterSignature

public ParameterSignature(Object... parameters)

Create a parameter list signature from an array (or variable argument list) of actuals.

Parameters:

parameters - A sequence of actual parameters from which the types are deduced. Any nulls in the list are treated to be of type Object.

Method Detail

accepts

public boolean accepts(ReflectionSupport.ParameterSignature typesOfActuals)

Determine if the given set of actual argument types would be accepted by a method with this parameter signature.

Parameters:

typesOfActuals - The types of the actual arguments to check against.

Returns:

True If the specified actual types would be accepted by a method with this parameter signature.

acceptanceCategory

public ReflectionSupport.ParameterAcceptanceCategory acceptanceCategory(ReflectionSupport.ParameterSignature typesOfActuals)

Determine if the given set of actual argument types would be accepted by a method with this parameter signature.

Parameters:

typesOfActuals - The types of the actual arguments to check against.

Returns:

True If the specified actual types would be accepted by a method with this parameter signature.

accepts

public boolean accepts(Object... actuals)

Determine if the given set of actual parameter values would be accepted by a method with this parameter signature.

Parameters:

actuals - The types of the actual arguments to check against.

Returns:

True If the specified actuals would be accepted by a method with this parameter signature.

isSubSignatureOf

public boolean isSubSignatureOf(ReflectionSupport.ParameterSignature other)

Determine if this signature is a subsignature of the other one, as defined by Section 8.4.2 of the JLS. Since generic parameters are represented as their erasures in this representation, the subsignature check boils down to an equality check.

Parameters:

other - The parameter signature to check against.

Returns:

True If this signature is a subsignature of the other.

isMoreSpecificThan

public boolean isMoreSpecificThan(ReflectionSupport.ParameterSignature other)

Determine if this parameter signature is more specific than the given parameter signature.

Parameters:

other - The other parameter signature to check against.

Returns:

True If this parameter signature is more specific than the other.

asArray

public Class<?>[] asArray()

Retrieve a plain array containing the parameter types in this signature.

Returns:

An array of Class values representing the parameter types in this parameter signature object.

toString

public String toString()

Overrides:

toString in class AbstractCollection<Class<?>>
