Constructor Detail

DefaultModelProcessor

public DefaultModelProcessor()

Creates a new DefaultModelProcessor instance.

Method Detail

isDefaultEnabled

public static boolean isDefaultEnabled()

Gets a flag indicating the processor is enabled by default.

The default enabled flag is controlled by system property org.jomc.model.modlet.DefaultModelProcessor.defaultEnabled holding a value indicating the processor is enabled by default. If that property is not set, the true default is returned.

Returns:

true, if the processor is enabled by default; false, if the processor is disabled by default.

See Also:

setDefaultEnabled(java.lang.Boolean)

setDefaultEnabled

public static void setDefaultEnabled(Boolean value)

Sets the flag indicating the processor is enabled by default.

Parameters:

value - The new value of the flag indicating the processor is enabled by default or null.

See Also:

isDefaultEnabled()

isEnabled

public final boolean isEnabled()

Gets a flag indicating the processor is enabled.

Returns:

true, if the processor is enabled; false, if the processor is disabled.

See Also:

isDefaultEnabled(), setEnabled(java.lang.Boolean)

setEnabled

public final void setEnabled(Boolean value)

Sets the flag indicating the processor is enabled.

Parameters:

value - The new value of the flag indicating the processor is enabled or null.

See Also:

isEnabled()

getDefaultTransformerLocation

public static String getDefaultTransformerLocation()

Gets the default location searched for transformer resources.

The default transformer location is controlled by system property org.jomc.model.modlet.DefaultModelProcessor.defaultTransformerLocation holding the location to search for transformer resources by default. If that property is not set, the META-INF/jomc.xsl default is returned.

Returns:

The location searched for transformer resources by default.

See Also:

setDefaultTransformerLocation(java.lang.String)

setDefaultTransformerLocation

public static void setDefaultTransformerLocation(String value)

Sets the default location searched for transformer resources.

Parameters:

value - The new default location to search for transformer resources or null.

See Also:

getDefaultTransformerLocation()

getTransformerLocation

public final String getTransformerLocation()

Gets the location searched for transformer resources.

Returns:

The location searched for transformer resources.

See Also:

getDefaultTransformerLocation(), setTransformerLocation(java.lang.String)

setTransformerLocation

public final void setTransformerLocation(String value)

Sets the location searched for transformer resources.

Parameters:

value - The new location to search for transformer resources or null.

See Also:

getTransformerLocation()

findTransformers

public List<Transformer> findTransformers(ModelContext context,
                                          String location)
                                   throws ModelException

Searches a given context for transformers.

Parameters:

context - The context to search for transformers.

location - The location to search at.

Returns:

The transformers found at location in context or null, if no transformers are found.

Throws:

NullPointerException - if context or location is null.

ModelException - if getting the transformers fails.

processModel

public Model processModel(ModelContext context,
                          Model model)
                   throws ModelException

Specified by:

processModel in interface ModelProcessor

Throws:

ModelException
