All Implemented Interfaces:

Substitution

public class ParameterizedGenericMethodBinding
extends ParameterizedMethodBinding
implements Substitution

Binding denoting a generic method after type parameter substitutions got performed. On parameterized type bindings, all methods got substituted, regardless whether their signature did involve generics or not, so as to get the proper declaringClass for these methods.

Constructor Summary

ParameterizedGenericMethodBinding(MethodBinding originalMethod, RawTypeBinding rawType, LookupEnvironment environment)
Create raw generic method for raw type (double substitution from type vars with raw type arguments, and erasure of method variables) Only invoked for non-static generic methods of raw type

ParameterizedGenericMethodBinding(MethodBinding originalMethod, TypeBinding[] typeArguments, LookupEnvironment environment)
Create method of parameterized type, substituting original parameters with type arguments.

Method Summary

static MethodBinding	computeCompatibleMethod(MethodBinding originalMethod, TypeBinding[] arguments, Scope scope, InvocationSite invocationSite) Perform inference of generic method type parameters and/or expected type
char[]	computeUniqueKey(boolean isLeaf)
LookupEnvironment	environment() Returns the lookup environment
boolean	hasSubstitutedParameters() Returns true if some parameters got substituted.
boolean	hasSubstitutedReturnType() Returns true if the return type got substituted.
boolean	isRawSubstitution() Returns true for raw substitution
TypeBinding	substitute(TypeVariableBinding originalVariable) Returns the type substitute for a given type variable, or itself if no substitution got performed.
MethodBinding	tiebreakMethod() Returns the method to use during tiebreak (usually the method itself).

ParameterizedGenericMethodBinding

public ParameterizedGenericMethodBinding(MethodBinding originalMethod,
                                         TypeBinding[] typeArguments,
                                         LookupEnvironment environment)

Create method of parameterized type, substituting original parameters with type arguments.

Method Detail

computeCompatibleMethod

public static MethodBinding computeCompatibleMethod(MethodBinding originalMethod,
                                                    TypeBinding[] arguments,

                                                    InvocationSite invocationSite)

Perform inference of generic method type parameters and/or expected type

computeUniqueKey

public char[] computeUniqueKey(boolean isLeaf)

Overrides:

computeUniqueKey in class MethodBinding

environment

public LookupEnvironment environment()

Description copied from interface: Substitution

Returns the lookup environment

Specified by:

environment in interface Substitution

See Also:

Substitution.environment()

hasSubstitutedParameters

public boolean hasSubstitutedParameters()

Returns true if some parameters got substituted. NOTE: generic method invocation delegates to its declaring method (could be a parameterized one)

Overrides:

hasSubstitutedParameters in class ParameterizedMethodBinding

hasSubstitutedReturnType

public boolean hasSubstitutedReturnType()

Returns true if the return type got substituted. NOTE: generic method invocation delegates to its declaring method (could be a parameterized one)

Overrides:

hasSubstitutedReturnType in class ParameterizedMethodBinding

isRawSubstitution

public boolean isRawSubstitution()

Description copied from interface: Substitution

Returns true for raw substitution

Specified by:

isRawSubstitution in interface Substitution

See Also:

Substitution.isRawSubstitution()

substitute

public TypeBinding substitute(TypeVariableBinding originalVariable)

Description copied from interface: Substitution

Returns the type substitute for a given type variable, or itself if no substitution got performed.

Specified by:

substitute in interface Substitution

See Also:

Substitution.substitute(org.eclipse.jdt.internal.compiler.lookup.TypeVariableBinding)

tiebreakMethod

public MethodBinding tiebreakMethod()

Description copied from class: MethodBinding

Returns the method to use during tiebreak (usually the method itself). For generic method invocations, tiebreak needs to use generic method with erasure substitutes.

Overrides:

tiebreakMethod in class MethodBinding

See Also:

MethodBinding.tiebreakMethod()
