Method Detail

### checkLimit

    public static int checkLimit(int limit)

  Checks whether the number of indexes to return is between 1 and the maximum.

  Parameters:
    `limit` - the maximum number of indexes to return in list results
  Returns:
    the checked number of indexes to return
  Throws:
    `java.lang.IllegalArgumentException` - if the number of indexes to return is out of range

### checkOffset

    public static int checkOffset(int offset)

  Checks whether the offset of the first indexes to return is between 0 and the maximum.

  Parameters:
    `offset` - the offset of the first index to return in list results
  Returns:
    the checked offset of the first index to return
  Throws:
    `java.lang.IllegalArgumentException` - if the offset of the first index to return is out of range

### checkIndexNamePrefix

    public static java.lang.String checkIndexNamePrefix(java.lang.String indexNamePrefix)

  Checks whether the given index name prefix is legal. This method uses the same checks as `IndexChecker.checkName(String)`.

  Parameters:
    `indexNamePrefix` - the index name prefix to be checked
  Returns:
    the checked index name prefix
  Throws:
    `java.lang.IllegalArgumentException` - if the index name prefix is illegal.

### checkStartIndexName

    public static java.lang.String checkStartIndexName(java.lang.String startIndexName)

  Checks whether the given start index name is legal. This method uses the same checks as `IndexChecker.checkName(String)`.

  Parameters:
    `startIndexName` - the name of the first index to be returned
  Returns:
    the checked start index name
  Throws:
    `java.lang.IllegalArgumentException` - if the start index name is illegal.

### checkListIndexesParams

    public static ListIndexesParams checkListIndexesParams(ListIndexesParams params)

  Ensures the given protocol buffer parameters are valid. If any of the parameters fail to pass the checks, this method throws `IllegalArgumentException`. If everything is valid the original parameters are returned.

  Parameters:
    `params` - the parameters to be checked for validity
  Returns:
    the checked parameters for listing indexes
  Throws:
    `java.lang.IllegalArgumentException` - if any of the values are incorrect
