## net.sf.saxon.lib
Class AugmentedSource

    java.lang.Object
      net.sf.saxon.lib.AugmentedSource

All Implemented Interfaces:
  Source

    public class AugmentedSource

extends Object
implements Source

This class is an extension of the JAXP Source interface. The class can be used wherever a JAXP Source object can be used, and it provides additional information about the way that the Source is to be processed: for example, it indicates whether or not it should be validated against a schema. Other options that can be set include the SAX XMLReader to be used, and the choice of whether a source in the form of an existing tree should be copied or wrapped.

Internally, an AugmentedSource combines an underlying Source object with a `ParseOptions` object holding the selected options. Many Saxon interfaces allow the ParseOptions to be supplied directly, making this class unnecessary; but it is useful when passing a Source to a JAXP interface that does not allow further options to be supplied.

Since:
  8.8

It is not used when the Source is supplied to a Saxon-defined interface.

### setEntityResolver

    public void setEntityResolver(EntityResolver resolver)

  Parameters:
    `resolver` - the EntityResolver to be used
  Since:
    8.9. The method had no useful effect in releases prior to 9.2.

### getEntityResolver

    public EntityResolver getEntityResolver()

  Get the EntityResolver that will be used when parsing

  Returns:
    the EntityResolver, if one has been set using `setEntityResolver(org.xml.sax.EntityResolver)`, otherwise null.
  Since:

    public ErrorListener getErrorListener()

  Get the ErrorListener that will be used when parsing

  Returns:
    the ErrorListener, if one has been set using `setErrorListener(javax.xml.transform.ErrorListener)`, otherwise null.
  Since:
    8.9

### setPleaseCloseAfterUse

    public void setPleaseCloseAfterUse(boolean close)

  Set whether or not the user of this Source is encouraged to close it as soon as reading is finished. Normally the expectation is that any Stream in a StreamSource will be closed by the component that created the Stream. However, in the case of a Source returned by a URIResolver, there is no suitable interface (the URIResolver has no opportunity to close the stream). Also, in some cases such as reading of stylesheet modules, it is possible to close the stream long before control is returned to the caller who supplied it. This tends to make a difference on .NET, where a file often can't be opened if there is a stream attached to it.

  Parameters:
    `close` - true if the source should be closed as soon as it has been consumed
  Since:
    8.8

### isPleaseCloseAfterUse

    public boolean isPleaseCloseAfterUse()

  Determine whether or not the user of this Source is encouraged to close it as soon as reading is finished.

  Returns:
    true if the source should be closed as soon as it has been consumed
  Since:
    8.8

### close

    public void close()

  Close any resources held by this Source. This only works if the underlying Source is one that is recognized as holding closable resources.

  Since:
    8.8
