Example 4 with InvalidRequestException

use of org.apache.cassandra.exceptions.InvalidRequestException in project cassandra by apache.

the class QueryOptions method getJsonColumnValue.

/**
     * Returns the term corresponding to column {@code columnName} in the JSON value of bind index {@code bindIndex}.
     *
     * This is functionally equivalent to:
     *   {@code Json.parseJson(UTF8Type.instance.getSerializer().deserialize(getValues().get(bindIndex)), expectedReceivers).get(columnName)}
     * but this cache the result of parsing the JSON so that while this might be called for multiple columns on the same {@code bindIndex}
     * value, the underlying JSON value is only parsed/processed once.
     *
     * Note: this is a bit more involved in CQL specifics than this class generally is but we as we need to cache this per-query and in an object
     * that is available when we bind values, this is the easier place to have this.
     *
     * @param bindIndex the index of the bind value that should be interpreted as a JSON value.
     * @param columnName the name of the column we want the value of.
     * @param expectedReceivers the columns expected in the JSON value at index {@code bindIndex}. This is only used when parsing the
     * json initially and no check is done afterwards. So in practice, any call of this method on the same QueryOptions object and with the same
     * {@code bindIndx} values should use the same value for this parameter, but this isn't validated in any way.
     *
     * @return the value correspong to column {@code columnName} in the (JSON) bind value at index {@code bindIndex}. This may return null if the
     * JSON value has no value for this column.
     */

    if (jsonValuesCache == null)
