Constructor Detail

HotSpotSignature

                        String signature)

HotSpotSignature

public HotSpotSignature(HotSpotJVMCIRuntimeProvider runtime,
                        ResolvedJavaType returnType,
                        ResolvedJavaType... parameterTypes)

Method Detail

parseSignature

private static int parseSignature(String signature,
                                  int start)

getParameterCount

public int getParameterCount(boolean withReceiver)

Description copied from interface: Signature

Returns the number of parameters in this signature, adding 1 for a receiver if requested.

Specified by:

getParameterCount in interface Signature

Parameters:

withReceiver - true if 1 is to be added to the result for a receiver

Returns:

the number of parameters; + 1 iff receiver == true

getParameterKind

public Kind getParameterKind(int index)

Description copied from interface: Signature

Gets the parameter kind at the specified position. This is the same as calling Signature.getParameterType(int, jdk.internal.jvmci.meta.ResolvedJavaType). getKind.

Specified by:

getParameterKind in interface Signature

Parameters:

index - the index into the parameters, with 0 indicating the first parameter

Returns:

the kind of the parameter at the specified position

checkValidCache

private static boolean checkValidCache(ResolvedJavaType type,
                                       ResolvedJavaType accessingClass)

getUnresolvedOrPrimitiveType

private static JavaType getUnresolvedOrPrimitiveType(HotSpotJVMCIRuntimeProvider runtime,
                                                     String name)

getParameterType

public JavaType getParameterType(int index,
                                 ResolvedJavaType accessingClass)

Description copied from interface: Signature

Gets the parameter type at the specified position.

Specified by:

getParameterType in interface Signature

Parameters:

index - the index into the parameters, with 0 indicating the first parameter

accessingClass - the context of the type lookup. If non-null, its class loader is used for resolving the type. If null, then the type returned is either unresolved or a resolved type whose resolution is context free (e.g., a primitive type or a type in a java.* package).

Returns:

the index'th parameter type

toMethodDescriptor

public String toMethodDescriptor()

Description copied from interface: Signature

Gets the method descriptor corresponding to this signature. For example:

 (ILjava/lang/String;D)V
 

Specified by:

toMethodDescriptor in interface Signature

Returns:

the signature as a string

getReturnKind

public Kind getReturnKind()

Description copied from interface: Signature

Gets the return kind of this signature. This is the same as calling Signature.getReturnType(jdk.internal.jvmci.meta.ResolvedJavaType). getKind.

Specified by:

getReturnKind in interface Signature

getReturnType

public JavaType getReturnType(ResolvedJavaType accessingClass)

Description copied from interface: Signature

Gets the return type of this signature.

Specified by:

getReturnType in interface Signature

Parameters:

accessingClass - the context of the type lookup. If non-null, its class loader is used for resolving the type. If null, then the type returned is either unresolved or a resolved type whose resolution is context free (e.g., a primitive type or a type in a java.* package).

Returns:

the return type

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
