TransformerFactory

public abstract class TransformerFactory

java.lang.Object
↳	javax.xml.transform.TransformerFactory

Known direct subclasses

SAXTransformerFactory

SAXTransformerFactory This class extends TransformerFactory to provide SAX-specific factory methods.

A TransformerFactory instance can be used to create Transformer and Templates objects.

The system property that determines which Factory implementation to create is named "javax.xml.transform.TransformerFactory". This property names a concrete subclass of the TransformerFactory abstract class. If the property is not defined, a platform default is be used.

Default constructor is protected on purpose.

Public methods

getAssociatedStylesheet

Added in API level 8

public abstract Source getAssociatedStylesheet (Source source, 
                String media, 
                String title, 
                String charset)

`media`	`String`: The media attribute to be matched. May be null, in which case the preferred templates will be used (i.e. alternate = no).
`title`	`String`: The value of the title attribute to match. May be null.
`charset`	`String`: The value of the charset attribute to match. May be null.

Returns
`Source`	A `Source` `Object` suitable for passing to the `TransformerFactory`.

Throws
`TransformerConfigurationException`	An `Exception` is thrown if an error occurs during parsing of the `source`.

getAttribute

Added in API level 8

public abstract Object getAttribute (String name)

Allows the user to retrieve specific attributes on the underlying implementation. An IllegalArgumentException is thrown if the underlying implementation doesn't recognize the attribute.

Parameters
`name`	`String`: The name of the attribute.

Returns
`Object`	value The value of the attribute.

getErrorListener

Added in API level 8

public abstract ErrorListener getErrorListener ()

Get the error event handler for the TransformerFactory.

Returns
`ErrorListener`	The current error handler, which should never be null.

getFeature

Added in API level 8

public abstract boolean getFeature (String name)

Look up the value of a feature.

Feature names are fully qualified URIs. Implementations may define their own features. false is returned if this TransformerFactory or the Transformers or Templates it creates cannot support the feature. It is possible for an TransformerFactory to expose a feature value but be unable to change its state.

Parameters
`name`	`String`: Feature name.

Returns
`boolean`	The current state of the feature, `true` or `false`.

Throws
`NullPointerException`	If the `name` parameter is null.

getURIResolver

Added in API level 8

public abstract URIResolver getURIResolver ()

Get the object that is used by default during the transformation to resolve URIs used in document(), xsl:import, or xsl:include.

Returns
`URIResolver`	The URIResolver that was set with setURIResolver.

newInstance

Added in API level 9

public static TransformerFactory newInstance (String factoryClassName, 
                ClassLoader classLoader)

Returns an instance of the named implementation of TransformerFactory.

Parameters
`factoryClassName`	`String`
`classLoader`	`ClassLoader`

Returns
`TransformerFactory`

Throws
`TransformerFactoryConfigurationError`	if `factoryClassName` is not available or cannot be instantiated.

newInstance

Added in API level 8

public static TransformerFactory newInstance ()

Returns Android's implementation of TransformerFactory. Unlike other Java implementations, this method does not consult system properties, properties files, or the services API.

Returns
`TransformerFactory`

Throws
`TransformerFactoryConfigurationError`	never. Included for API compatibility with other Java implementations.

newTemplates

Added in API level 8

public abstract Templates newTemplates (Source source)

Process the Source into a Templates object, which is a a compiled representation of the source. This Templates object may then be used concurrently across multiple threads. Creating a Templates object allows the TransformerFactory to do detailed performance optimization of transformation instructions, without penalizing runtime transformation.

Parameters
`source`	`Source`: An object that holds a URL, input stream, etc.

Returns
`Templates`	A Templates object capable of being used for transformation purposes, never null.

Throws
`TransformerConfigurationException`	May throw this during the parse when it is constructing the Templates object and fails.

newTransformer

Added in API level 8

public abstract Transformer newTransformer (Source source)

Process the Source into a Transformer Object. The Source is an XSLT document that conforms to XSL Transformations (XSLT) Version 1.0. Care must be taken not to use this Transformer in multiple Threads running concurrently. Different TransformerFactories can be used concurrently by different Threads.

Parameters
`source`	`Source`: `Source` of XSLT document used to create `Transformer`. Examples of XML `Source`s include `StreamSource`, `SAXSource` and `DOMSource`.

Returns
`Transformer`	A `Transformer` object that may be used to perform a transformation in a single `Thread`, never `null`.

Throws
`TransformerConfigurationException`	Thrown if there are errors when parsing the `Source` or it is not possible to create a `Transformer` instance.

newTransformer

Added in API level 8

public abstract Transformer newTransformer ()

Create a new Transformer that performs a copy of the Source to the Result. i.e. the "identity transform".

Returns
`Transformer`	A Transformer object that may be used to perform a transformation in a single thread, never null.

Throws
`TransformerConfigurationException`	Thrown if it is not possible to create a `Transformer` instance.

setAttribute

Added in API level 8

public abstract void setAttribute (String name, 
                Object value)

Allows the user to set specific attributes on the underlying implementation. An attribute in this context is defined to be an option that the implementation provides. An IllegalArgumentException is thrown if the underlying implementation doesn't recognize the attribute.

Parameters
`name`	`String`: The name of the attribute.
`value`	`Object`: The value of the attribute.

setErrorListener

Added in API level 8

public abstract void setErrorListener (ErrorListener listener)

Set the error event listener for the TransformerFactory, which is used for the processing of transformation instructions, and not for the transformation itself. An IllegalArgumentException is thrown if the ErrorListener listener is null.

Parameters
`listener`	`ErrorListener`: The new error listener.

setFeature

Added in API level 8

public abstract void setFeature (String name, 
                boolean value)

Set a feature for this TransformerFactory and Transformers or Templates created by this factory.

Feature names are fully qualified URIs. Implementations may define their own features. An TransformerConfigurationException is thrown if this TransformerFactory or the Transformers or Templates it creates cannot support the feature. It is possible for an TransformerFactory to expose a feature value but be unable to change its state.

All implementations are required to support the XMLConstants.FEATURE_SECURE_PROCESSING feature. When the feature is:

true: the implementation will limit XML processing to conform to implementation limits and behave in a secure fashion as defined by the implementation. Examples include resolving user defined style sheets and functions. If XML processing is limited for security reasons, it will be reported via a call to the registered ErrorListener#fatalError(TransformerException exception). See setErrorListener(javax.xml.transform.ErrorListener).
false: the implementation will processing XML according to the XML specifications without regard to possible implementation limits.

Parameters
`name`	`String`: Feature name.
`value`	`boolean`: Is feature state `true` or `false`.

Throws
`TransformerConfigurationException`	if this `TransformerFactory` or the `Transformer`s or `Template`s it creates cannot support this feature.
`NullPointerException`	If the `name` parameter is null.

setURIResolver

Added in API level 8

public abstract void setURIResolver (URIResolver resolver)

Set an object that is used by default during the transformation to resolve URIs used in document(), xsl:import, or xsl:include.

Parameters
`resolver`	`URIResolver`: An object that implements the URIResolver interface, or null.
