示例1: parseInt32

import com.fasterxml.jackson.core.JsonToken; //导入依赖的package包/类
/** Parsers an int32 value out of the input. */
static int parseInt32(JsonParser parser) throws IOException {
  JsonToken token = parser.currentToken();
  if (token == JsonToken.VALUE_NUMBER_INT) {
    // Use optimized code path for integral primitives, the normal case.
    return parser.getIntValue();
  }
  // JSON doesn't distinguish between integer values and floating point values so "1" and
  // "1.000" are treated as equal in JSON. For this reason we accept floating point values for
  // integer fields as well as long as it actually is an integer (i.e., round(value) == value).
  try {
    BigDecimal value =
        new BigDecimal(
            parser.getTextCharacters(), parser.getTextOffset(), parser.getTextLength());
    return value.intValueExact();
  } catch (Exception e) {
    throw new InvalidProtocolBufferException("Not an int32 value: " + parser.getText());
  }
