Class FunctionEncoder

java.lang.Object

org.tron.trident.abi.FunctionEncoder

Direct Known Subclasses:

DefaultFunctionEncoder

public abstract class FunctionEncoder
extends java.lang.Object

Delegates to DefaultFunctionEncoder unless a FunctionEncoderProvider SPI is found, in which case the first implementation found will be used.

Method Detail

encode

public static java.lang.String encode(Function function)

encode

public static java.lang.String encode(java.lang.String methodId,
                                      java.util.List<Type> parameters)

Encode function when we know function method Id / Selector.

encodeConstructor

public static java.lang.String encodeConstructor(java.util.List<Type> parameters)

encodeConstructorPacked

public static java.lang.String encodeConstructorPacked(java.util.List<Type> parameters)

makeFunction

public static Function makeFunction(java.lang.String fnname,
                                    java.util.List<java.lang.String> solidityInputTypes,
                                    java.util.List<java.lang.Object> arguments,
                                    java.util.List<java.lang.String> solidityOutputTypes)
                             throws java.lang.ClassNotFoundException,
                                    java.lang.NoSuchMethodException,
                                    java.lang.InstantiationException,
                                    java.lang.IllegalAccessException,
                                    java.lang.reflect.InvocationTargetException

Throws:

java.lang.ClassNotFoundException

java.lang.NoSuchMethodException

java.lang.InstantiationException

java.lang.IllegalAccessException

java.lang.reflect.InvocationTargetException

encodeFunction

protected abstract java.lang.String encodeFunction(Function function)

encodeParameters

protected abstract java.lang.String encodeParameters(java.util.List<Type> parameters)

encodeWithSelector

protected java.lang.String encodeWithSelector(java.lang.String methodId,
                                              java.util.List<Type> parameters)

Encodes parameters prefixed with the given selector. Not part of the original subclass contract: implementations predating it inherit this throwing default, so the pre-existing entry points keep working and only the newer encode(String, List) fails, with a clear message.

Parameters:

methodId - Callback selector / Abi method Id (Hex format)

encodePackedParameters

protected java.lang.String encodePackedParameters(java.util.List<Type> parameters)

Encodes parameters using tight packing (abi.encodePacked). Not part of the original subclass contract; see encodeWithSelector(String, List).

buildMethodSignature

protected static java.lang.String buildMethodSignature(java.lang.String methodName,
                                                       java.util.List<Type> parameters)

buildMethodId

protected static java.lang.String buildMethodId(java.lang.String methodSignature)
