Method Detail

getCanonicalName

public java.lang.String getCanonicalName()

Description copied from interface: TemplateDataSource

Returns a canonical name of this TemplateDataSource.

The name returned here is used to look up the parsing result of the internal caching, so it should differ for all different TemplateDataSource objects :-)

May return null if this TemplateDataSource is supposed to be parsed each time. The canonical name would be something like a filename or an URL.

Returns:

a unique name of the TemplateDataSource

See Also:

TemplateDataSource.getCanonicalName()

getInputStream

public java.io.InputStream getInputStream()
                                   throws java.io.IOException

Description copied from interface: TemplateDataSource

Gets an InputStream of this TemplateDataSource.

Note that this method may be called multiple times in the life of the TemplateDataSource. So you probably have to implement a buffer if your underlying data source is transient ..

Returns:

a InputStream containing the template data

Throws:

java.io.IOException

See Also:

TemplateDataSource.getInputStream()

getFile

public java.io.File getFile()

Returns:

Returns the file.
