Method Detail

isEmpty

public boolean isEmpty()
                throws ToolsException

Description copied from interface: Sequence

Return true if the sequence is empty.

Specified by:

isEmpty in interface Sequence

Returns:

true if this sequence is empty.

Throws:

ToolsException - If there is any technical error computing the result.

next

public Sequence next()
              throws ToolsException

Description copied from interface: Sequence

Return the next item in the sequence, as a sequence itself (a singleton). Each call to this method increment the current position, so the first call returns the first item in the sequence, then the second call returns the second item, etc. Return null if there is no more item to consume in the sequence.

Specified by:

next in interface Sequence

Returns:

The next item in the sequence (as a singleton sequence).

Throws:

ToolsException - If there is any technical error accessing or building the result.

serialize

public void serialize(java.io.OutputStream out,
                      SerialParameters params)
               throws ToolsException

Description copied from interface: Sequence

Serialize the sequence to the output stream, using the serialization parameters. See JAXP's OutputKeys for the serialization parameters, as well as the recommendation "XSLT and XQuery Serialization".

Specified by:

serialize in interface Sequence

Parameters:

out - The destination of the output.

params - The serialization parameters to use.

Throws:

ToolsException - If there is any error serializing the sequence or writing to out.
