Class Base64Data

java.lang.Object
org.glassfish.jaxb.runtime.v2.runtime.output.Pcdata
org.glassfish.jaxb.runtime.v2.runtime.unmarshaller.Base64Data
All Implemented Interfaces:
CharSequence
public final class Base64Data extends Pcdata
Fed to unmarshaller when the 'text' data is actually a virtual image of base64 encoding of the binary data transferred on the wire. Used for the MTOM support. This object is mutable and the owner of this object can reuse it with new data. Also used by the marshaller to write out the binary data that could be possibly attached.

    • Base64Data

      public Base64Data()
      Default constructor.

  • Method Details

    • set

      public void set(byte[] data, int len, @Nullable String mimeType)
      Fills in the data object by a portion of the byte[].
      Parameters:
      len - data[0] to data[len-1] are treated as the data.

    • set

      public void set(byte[] data, @Nullable String mimeType)
      Fills in the data object by the byte[] of the exact length.
      Parameters:
      data - this buffer may be owned directly by the unmarshaleld JAXB object.

    • set

      public void set(DataHandler data)
      Fills in the data object by a DataHandler.

    • getDataHandler

      public DataHandler getDataHandler()
      Gets the raw data.

    • getExact

      public byte[] getExact()
      Gets the byte[] of the exact length.

    • getInputStream

      public InputStream getInputStream() throws IOException
      Gets the data as an InputStream.
      Throws:
      IOException

    • hasData

      public boolean hasData()
      Returns false if this object only has DataHandler and therefore get() operation is likely going to be expensive.

    • get

      public byte[] get()
      Gets the raw data. The size of the byte array maybe larger than the actual length.

    • getDataLen

      public int getDataLen()

    • getMimeType

      public String getMimeType()

    • length

      public int length()
      Gets the number of characters needed to represent this binary data in the base64 encoding.

    • charAt

      public char charAt(int index)
      Encode this binary data in the base64 encoding and returns the character at the specified position.

    • subSequence

      public CharSequence subSequence(int start, int end)
      Internally this is only used to split a text to a list, which doesn't happen that much for base64. So this method should be smaller than faster.

    • toString

      public String toString()
      Returns the base64 encoded string of this data.
      Specified by:
      toString in interface CharSequence
      Specified by:
      toString in class Pcdata

    • writeTo

      public void writeTo(char[] buf, int start)
      Description copied from class: Pcdata
      Writes itself to the character array.

      This method is used by most other XmlOutput. The default implementation involves in one extra char[] copying.

      The caller must provide a big enough buffer that can hold enough characters returned by the CharSequence.length() method.

      Overrides:
      writeTo in class Pcdata

    • writeTo

      public void writeTo(UTF8XmlOutput output) throws IOException
      Description copied from class: Pcdata
      Writes itself to UTF8XmlOutput.

      This is the most performance critical path for the marshaller, so it warrants its own method.

      Specified by:
      writeTo in class Pcdata
      Throws:
      IOException

    • writeTo

      public void writeTo(XMLStreamWriter output) throws IOException, XMLStreamException
      Throws:
      IOException
      XMLStreamException
