Class PreparedStylesheet

    java.lang.Object
      net.sf.saxon.expr.instruct.Executable
          net.sf.saxon.PreparedStylesheet

All Implemented Interfaces:
  Serializable, Templates

    public class PreparedStylesheet

extends Executable
implements Templates, Serializable

This PreparedStylesheet class represents a Stylesheet that has been prepared for execution (or "compiled").

Note that the PreparedStylesheet object does not contain a reference to the source stylesheet tree (rooted at an XSLStyleSheet object). This allows the source tree to be garbage-collected when it is no longer required.

  Serialized Form

  Since:
    8.9

### getOutputProperties

    public Properties getOutputProperties()

  Get the properties for xsl:output. JAXP method. The object returned will be a clone of the internal values, and thus it can be mutated without mutating the Templates object, and then handed in to the process method.

  In Saxon, the properties object is a new, empty, Properties object that is backed by the live properties to supply default values for missing properties. This means that the property values must be read using the getProperty() method. Calling the get() method on the underlying Hashtable will return null.

  In Saxon 8.x, this method gets the output properties for the unnamed output format in the stylesheet.

  Specified by:
    `getOutputProperties` in interface `Templates`
  Returns:
    A Properties object reflecting the output properties defined for the default (unnamed) output format in the stylesheet. It may be mutated and supplied to the setOutputProperties() method of the Transformer, without affecting other transformations that use the same stylesheet.
  See Also:
    `Transformer.setOutputProperties(java.util.Properties)`

### reportError

    public void reportError(TransformerException err)
                     throws TransformerException

  Report a compile time error. This calls the errorListener to output details of the error, and increments an error count.

  Parameters:
    `err` - the exception containing details of the error
  Throws:
    `TransformerException` - if the ErrorListener decides that the error should be reported

### getErrorCount

    public int getErrorCount()

  Get the number of errors reported so far

  Returns:
    the number of errors reported

### reportWarning

    public void reportWarning(TransformerException err)

  Report a compile time warning. This calls the errorListener to output details of the warning.

  Parameters:
    `err` - an exception holding details of the warning condition to be reported

### getCachedStylesheet

    public PreparedStylesheet getCachedStylesheet(String href,
                                                  String baseURI)
