Class AugmentedSource

java.lang.Object
  extended by net.sf.saxon.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.

8.8

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
