Java JsonToken類代碼示例

本文整理匯總了Java中com.fasterxml.jackson.core.JsonToken類的典型用法代碼示例。如果您正苦於以下問題：Java JsonToken類的具體用法？Java JsonToken怎麽用？Java JsonToken使用的例子？那麽, 這裏精選的類代碼示例或許可以為您提供幫助。


JsonToken類屬於com.fasterxml.jackson.core包，在下文中一共展示了JsonToken類的15個代碼示例，這些例子默認根據受歡迎程度排序。您可以為喜歡或者感覺有用的代碼點讚，您的評價將有助於係統推薦出更棒的Java代碼示例。

示例1: parseInt32

import com.fasterxml.jackson.core.JsonToken; //導入依賴的package包/類
/** 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());
  }
