Direct Known Subclasses:

WstxOutputFactory

public abstract class XMLOutputFactory2

extends javax.xml.stream.XMLOutputFactory

Extension of XMLInputFactory to add missing functionality (which currently means 'nothing'...)

Also contains extended standard properties that conforming stream writer factory and instance implementations should at least recognize, and preferably support.
NOTE: although actual values for the property names are visible, implementations should try to use the symbolic constants defined here instead, to avoid typos.

Field Summary

static java.lang.String	P_ATTR_VALUE_ESCAPER Property that can be set if a custom output escaping for attribute value content is needed.
static java.lang.String	P_AUTOMATIC_EMPTY_ELEMENTS Whether stream writers are allowed to automatically output empty elements, when a start element is immediately followed by matching end element.
static java.lang.String	P_AUTOMATIC_NS_PREFIX Prefix to use for automatically created namespace prefixes, when namespace support is enabled, the writer is in "repairing" mode, and a new prefix name is needed.
static java.lang.String	P_NAMESPACE_AWARE Whether output classes should keep track of and output namespace information provided via write methods.
static java.lang.String	P_TEXT_ESCAPER Property that can be set if a custom output escaping for textual content is needed.

Field Detail

P_AUTOMATIC_EMPTY_ELEMENTS

public static final java.lang.String P_AUTOMATIC_EMPTY_ELEMENTS

Whether stream writers are allowed to automatically output empty elements, when a start element is immediately followed by matching end element. If true, will output empty elements; if false, will always create separate end element (unless a specific method that produces empty elements is called).

Default value for implementations should be 'true'; both values should be recognized, and 'false' must be honored. However, 'true' value is only a suggestion, and need not be implemented (since there is the explicit 'writeEmptyElement()' method).

Constant Field Values

P_NAMESPACE_AWARE

public static final java.lang.String P_NAMESPACE_AWARE

Whether output classes should keep track of and output namespace information provided via write methods.

When enabled (set to Boolean.TRUE), will use all namespace information provided, and does not allow colons in names (local name, prefix). What exactly is kept track of depends on other settings, specifically whether writer is in "repairing" mode or not.

When disabled, will only make use of local name part, which may contain colons, and ignore prefix and namespace URI if any are passed.

Turning this option off may improve performance if no namespace handling is needed.

Default value for implementations should be 'true'; implementations are not required to implement 'false'.

Constant Field Values

P_AUTOMATIC_NS_PREFIX

public static final java.lang.String P_AUTOMATIC_NS_PREFIX

Prefix to use for automatically created namespace prefixes, when namespace support is enabled, the writer is in "repairing" mode, and a new prefix name is needed. The value is a String, and needs to be a valid namespace prefix in itself, as defined by the namespace specification. Will be prepended by a trailing part (often a sequence number), in order to make it unique to be usable as a temporary non-colliding prefix.

Constant Field Values

P_TEXT_ESCAPER

public static final java.lang.String P_TEXT_ESCAPER

Property that can be set if a custom output escaping for textual content is needed. The value set needs to be of type EscapingWriterFactory. When set, the factory will be used to create a per-writer instance used to escape all textual content written, both via explicit XMLStreamWriter.writeCharacters(java.lang.String) methods, and via copy methods (XMLStreamWriter2.copyEventFromReader(org.codehaus.stax2.XMLStreamReader2, boolean)).

Constant Field Values

P_ATTR_VALUE_ESCAPER

public static final java.lang.String P_ATTR_VALUE_ESCAPER

Property that can be set if a custom output escaping for attribute value content is needed. The value set needs to be of type EscapingWriterFactory. When set, the factory will be used to create a per-writer instance used to escape all attribute values written, both via explicit XMLStreamWriter.writeAttribute(java.lang.String, java.lang.String) methods, and via copy methods (XMLStreamWriter2.copyEventFromReader(org.codehaus.stax2.XMLStreamReader2, boolean)).

createXMLEventWriter

public abstract javax.xml.stream.XMLEventWriter createXMLEventWriter(java.io.Writer w,
                                                                     java.lang.String encoding)

Throws:

javax.xml.stream.XMLStreamException

createXMLStreamWriter

public abstract XMLStreamWriter2 createXMLStreamWriter(java.io.Writer w,
                                                       java.lang.String encoding)
                                                throws javax.xml.stream.XMLStreamException

Throws:

javax.xml.stream.XMLStreamException

configureForXmlConformance

public abstract void configureForXmlConformance()

Method call to make writer be as strict with output as possible, ie maximize validation it does to try to catch any well-formedness or validity problems.

This configuration does add some overhead to output process, since it enables content checks that are overhead.

None of currently defined standard properties should be affected, but implementations are likely to enable/disable custom properties related to validation.

configureForRobustness

public abstract void configureForRobustness()

Method call to make writer be as robust as possible, that is, to make it both check AND fix problems if it can.

Like configureForXmlConformance(), this configuration adds some overhead to output process.

None of currently defined standard properties should be affected, but implementations are likely to enable/disable custom properties related to validation.

configureForSpeed

public abstract void configureForSpeed()

Method call to make writer optimize its operation for speed. This generally disably additional checks (if any) writer does, and is likely to disable many things that configureForXmlConformance() (and configureForRobustness()) enables.

None of currently defined standard properties should be affected.
