javax.jcr.query.Row

Row
public interface Row (Code)
A row in the query result table.




Method Summary
public  NodegetNode()
     Returns the Node corresponding to this Row.

A RepositoryException is thrown if this Row contains values from more than one node.

public  NodegetNode(String selectorName)
     Returns the Node corresponding to this Row and the specified selector.
public  StringgetPath()
     Equivalent to Row.getNode().getPath().
public  StringgetPath(String selectorName)
     Equivalent to Row.getNode(selectorName).getPath().
public  doublegetScore()
     Returns the full text search score for this row associated with the default selector.
public  doublegetScore(String selectorName)
     Returns the full text search score for this row associated with the specified selector.
public  ValuegetValue(String columnName)
     Returns the value of the indicated column in this Row.
public  Value[]getValues()
     Returns an array of all the values in the same order as the column names returned by QueryResult.getColumnNames .



Method Detail
getNode
public Node getNode() throws RepositoryException(Code)
Returns the Node corresponding to this Row.

A RepositoryException is thrown if this Row contains values from more than one node. This will be the case when more than one selector is included among the columns specified for the query. a Node
throws:
  RepositoryException - if this query has more than one selector(and therefore, this Row corresponds to more than oneNode) or if another error occurs.
since:
   JCR 2.0




getNode
public Node getNode(String selectorName) throws RepositoryException(Code)
Returns the Node corresponding to this Row and the specified selector.
Parameters:
  selectorName - a String a Node
throws:
  RepositoryException - if selectorName is not the aliasof a selector in this query or if another error occurs.
since:
   JCR 2.0



getPath
public String getPath() throws RepositoryException(Code)
Equivalent to Row.getNode().getPath(). However, some implementations may be able gain efficiency by not resolving the actual Node. a String
throws:
  RepositoryException - if this query has more than one selector(and therefore, this Row corresponds to more than oneNode) or if another error occurs.
since:
   JCR 2.0



getPath
public String getPath(String selectorName) throws RepositoryException(Code)
Equivalent to Row.getNode(selectorName).getPath(). However, some implementations may be able gain efficiency by not resolving the actual Node.
Parameters:
  selectorName - a String a String
throws:
  RepositoryException - if selectorName is not the aliasof a selector in this query or if another error occurs.
since:
   JCR 2.0



getScore
public double getScore() throws RepositoryException(Code)
Returns the full text search score for this row associated with the default selector. This corresponds to the score of a particular node.

If no FullTextSearchScore AQM object is associated with the default selector this method will still return a value. However, in that case the returned value may not be meaningful or may simply reflect the minimum possible relevance level (for example, in some systems this might be a score of 0).

Note, in JCR-SQL2 a FullTextSearchScore AQM object is represented by a SCORE() function. In JCR-JQOM it is represented by a Java object of type javax.jcr.query.qom.FullTextSearchScore. a double
throws:
  RepositoryException - if this query has more than one selector(and therefore, this Row corresponds to more than oneNode) or if another error occurs.
since:
   JCR 2.0




getScore
public double getScore(String selectorName) throws RepositoryException(Code)
Returns the full text search score for this row associated with the specified selector. This corresponds to the score of a particular node.

If no FullTextSearchScore AQM object is associated with the selector selectorName this method will still return a value. However, in that case the returned value may not be meaningful or may simply reflect the minimum possible relevance level (for example, in some systems this might be a score of 0).

Note, in JCR-SQL2 a FullTextSearchScore AQM object is represented by a SCORE() function. In JCR-JQOM it is represented by a Java object of type javax.jcr.query.qom.FullTextSearchScore.
Parameters:
  selectorName - a String a String
throws:
  RepositoryException - if selectorName is not the aliasof a selector in this query or if another error occurs.
since:
   JCR 2.0




getValue
public Value getValue(String columnName) throws ItemNotFoundException, RepositoryException(Code)
Returns the value of the indicated column in this Row.

If columnName is not among the column names of the query result table, an ItemNotFoundException is thrown.

  columnName - name of query result table column a Value
throws:
  ItemNotFoundException - if columnName s not among thecolumn names of the query result table.
throws:
  RepositoryException - if anopther error occurs.
