方法详细资料

decode

public java.util.List<Type> decode(java.lang.String rawInput,
                                   java.util.List<TypeReference<Type>> outputParameters)

Decode ABI encoded return values from smart contract function call.

指定者:

decode 在接口中 FunctionReturnDecoderInterface

参数:

rawInput - ABI encoded input

outputParameters - list of return types as TypeReference

返回:

List of values returned by function, Collections.emptyList() if invalid response

decodeIndexedValue

public <T extends Type> Type decodeIndexedValue(java.lang.String rawInput,
                                                TypeReference<T> typeReference)

Decodes an indexed parameter associated with an event. Indexed parameters are individually encoded, unlike non-indexed parameters which are encoded as per ABI-encoded function parameters and return values.

If any of the following types are indexed, the Keccak-256 hashes of the values are returned instead. These are returned as a bytes32 value.

• Arrays
• Strings
• Bytes

See the Solidity documentation for further information.

指定者:

decodeIndexedValue 在接口中 FunctionReturnDecoderInterface

类型参数:

T - type of TypeReference

参数:

rawInput - ABI encoded input

typeReference - of expected result type

返回:

the decode value

getDataOffset

public static <T extends Type> int getDataOffset(byte[] input,
                                                 int offset,
                                                 TypeReference<?> typeReference)
                                          throws java.lang.ClassNotFoundException

抛出:

java.lang.ClassNotFoundException
