## org.modeshape.graph.query
Interface QueryResults

All Superinterfaces:
  Serializable

All Known Implementing Classes:
  QueryResults

    @Immutable
    public interface QueryResults

extends Serializable

The resulting output of a query.

Nested Class Summary
`static interface` | `QueryResults.Columns` Definition of the columns that are available in the results, which outline the structure of the `tuples` in the results, and which can be used to access the individual values in each of the tuples.
`static interface` | `QueryResults.Cursor` An interface used to walk through the results.
`static class` | `QueryResults.Statistics`

Field Summary
`static ThreadLocal<DecimalFormat>` | `FORMATTER`

Method Summary
`QueryResults.Columns` | `getColumns()` Get the description of the columns contained in these results.
`QueryResults.Cursor` | `getCursor()` Get a cursor that can be used to walk through the results.
`String` | `getPlan()` Get a description of the query plan, if requested.
`Problems` | `getProblems()` Get the problems encountered during execution.
`int` | `getRowCount()` Get the number of rows in the results.
`QueryResults.Statistics` | `getStatistics()` Get the statistics that describe the time metrics for this query.
`List<Object[]>` | `getTuples()` Get the actual tuples that contain the results.
`boolean` | `hasErrors()` Return true if there is at least one error recorded in the `problems`.
`boolean` | `hasWarnings()` Return true if there is at least one warning recorded in the `problems`.

Field Detail

### FORMATTER

    static final ThreadLocal<DecimalFormat> FORMATTER

Method Detail

### getColumns

    QueryResults.Columns getColumns()

  Get the description of the columns contained in these results. These columns can be used to discover the indexes of the corresponding values from the arrays representing the `tuples`.

  Returns:
    the column descriptions; never null

### getCursor

    QueryResults.Cursor getCursor()

  Get a cursor that can be used to walk through the results.

  Returns:
    the cursor; never null, though possibly empty (meaning `QueryResults.Cursor.hasNext()` may return true)

### getTuples

    List<Object[]> getTuples()

  Get the actual tuples that contain the results. Each element in the list represents a tuple, and each tuple corresponds to the column definitions.

  Returns:
    the list of tuples; never null but possibly empty

### getRowCount

    int getRowCount()

  Get the number of rows in the results.

  Returns:
    the number of rows; never negative

### getPlan

    String getPlan()

  Get a description of the query plan, if requested.

  Returns:
    the query plan, or null if the plan was not requested

### getProblems

    Problems getProblems()

  Get the problems encountered during execution.

  Returns:
    the problems; never null but possibly empty

### hasErrors

    boolean hasErrors()

  Return true if there is at least one error recorded in the `problems`.

  Returns:
    true if there is one or more errors associated with the query, or false otherwise

### hasWarnings

    boolean hasWarnings()

  Return true if there is at least one warning recorded in the `problems`.

  Returns:
    true if there is one or more warnings associated with the query, or false otherwise

### getStatistics

    QueryResults.Statistics getStatistics()

  Get the statistics that describe the time metrics for this query.

  Returns:
    the statistics; never null
