Class MethodDescriptor

java.lang.Object

proguard.classfile.MethodDescriptor

public class MethodDescriptor
extends java.lang.Object

Represents the descriptor that is part of a MethodSignature. A descriptor consists of parameter types and return type of a method, e.g. "()V" for a void method with no parameters, or "(II)B" for a method that takes two integers and returns a boolean. Read more about this topic in §4.3.3 of the JVM specification.

matchesIgnoreNull

public static boolean matchesIgnoreNull(MethodDescriptor descriptor,
                                        MethodDescriptor wildcard)

Analogous to MethodSignature.matchesIgnoreNull(MethodSignature, MethodSignature).

Parameters:

descriptor - The MethodDescriptor to be compared

wildcard - The MethodDescriptor pattern to be matched against

Returns:

true if the two objects match

matchesIgnoreNullAndDollar

public static boolean matchesIgnoreNullAndDollar(MethodDescriptor descriptor,
                                                 MethodDescriptor wildcard)

Analogous to MethodSignature.matchesIgnoreNullAndDollar(MethodSignature, MethodSignature).

Parameters:

descriptor - The MethodDescriptor to be compared

wildcard - The MethodDescriptor pattern to be matched against

Returns:

true if the two objects match

getPrettyReturnType

public java.lang.String getPrettyReturnType()

Get the human readable representation of the return type. E.g. "void" for "V" or "?" for an undefined return type.

Returns:

The human readable representation of returnType

getPrettyArgumentTypes

public java.lang.String getPrettyArgumentTypes()

Get the human readable representation of the argument types. E.g. "String,int" for "(Ljava/lang/String;I)".

Returns:

The human readable representation of argumentTypes
