private MethodSpec.Builder generateIntTypes(MethodSpec.Builder builder, String packageName) {
    for (int bitSize = 8; bitSize <= Type.MAX_BIT_LENGTH; bitSize += 8) {
        builder = addStatement(builder, packageName, Uint.TYPE_NAME + bitSize, Uint.class.getSimpleName() + bitSize);
        builder = addStatement(builder, packageName, Int.TYPE_NAME + bitSize, Int.class.getSimpleName() + bitSize);

Example 2 with Int

use of org.bcos.web3j.abi.datatypes.Int in project web3sdk by FISCO-BCOS.

the class TypeDecoder method decodeNumeric.

static <T extends NumericType> T decodeNumeric(String input, Class<T> type) {
    try {
        byte[] inputByteArray = Numeric.hexStringToByteArray(input);
        int typeLengthAsBytes = getTypeLengthInBytes(type);
        byte[] resultByteArray = new byte[typeLengthAsBytes + 1];
        if (Int.class.isAssignableFrom(type) || Fixed.class.isAssignableFrom(type)) {

    } catch (NoSuchMethodException | SecurityException | InstantiationException | IllegalAccessException | IllegalArgumentException | InvocationTargetException e) {
        throw new UnsupportedOperationException("Unable to create instance of " + type.getName(), e);
