Class Stax2BlockSource

  • All Implemented Interfaces:
    javax.xml.transform.Source
    Direct Known Subclasses:
    Stax2ByteArraySource, Stax2CharArraySource, Stax2StringSource

    public abstract class Stax2BlockSource
    extends Stax2Source
    This is the mid-level abstract base class for Stax2Sources that an be used to access fixed-length in-memory data sources, such as byte and char arrays, Strings, StringBuffers and so forth. The main reason for using such a source object (instead of constructing wrapper Readers or InputStreams) is that concrete implementations usually also allow more direct access to the underlying data, so that stream reader implementations may be able to do more optimal access.

      • getReference

        public java.net.URL getReference()
        Usually there is no way to refer to the underlying data source, since they are in-memory data structures. Because of this, the base implementation just returns null.
        Specified by:
        getReference in class Stax2Source
        Returns:
        URL that can be used to resolve references originating from the content read via this source; may be null if not known (which is the case for most non-referential sources)
      • constructReader

        public abstract java.io.Reader constructReader()
                                                throws java.io.IOException
        Description copied from class: Stax2Source
        This method creates a Reader via which underlying input source can be accessed. Note that caller is responsible for closing that Reader when it is done reading it.
        Specified by:
        constructReader in class Stax2Source
        Throws:
        java.io.IOException
      • constructInputStream

        public abstract java.io.InputStream constructInputStream()
                                                          throws java.io.IOException
        Description copied from class: Stax2Source
        This method creates an InputStream via which underlying input source can be accessed. Note that caller is responsible for closing that InputSource when it is done reading it
        Specified by:
        constructInputStream in class Stax2Source
        Throws:
        java.io.IOException
