public static java.util.Map<java.lang.String,java.lang.Object> createContentDescription(ContentHandler.Validity validity)
ContentHandler.VALIDITY_PROPERTY to the given validity value.
validity - the value of the validity property.
ContentHandler.VALIDITY_PROPERTY to the given validity value.protected java.util.Set<java.lang.String> getRequestedProperties(java.util.Map<?,?> options)
ContentHandler.OPTION_REQUESTED_PROPERTIES in the options map.
options - the options in which to look up the property.
ContentHandler.OPTION_REQUESTED_PROPERTIES in the options map.
protected boolean isRequestedProperty(java.lang.String property,
java.util.Map<?,?> options)
property - the property in question.options - the options in which to look for the requested property.
getRequestedProperties(Map)public boolean canHandle(URI uri)
canHandle in interface ContentHandleruri - the URI in questions.
public java.util.Map<java.lang.String,java.lang.Object> contentDescription(URI uri,
java.io.InputStream inputStream,
java.util.Map<?,?> options,
java.util.Map<java.lang.Object,java.lang.Object> context)
throws java.io.IOException
ContentHandler.BYTE_ORDER_MARK_PROPERTY if that's a requested property.
contentDescription in interface ContentHandleruri - the URI for which to determine the content description.inputStream - the input stream associated with the given URI.options - a map of options to direct what kind of description is needed.context - a map of contextual information that content handlers use to store partially computed results.
java.io.IOException - if there is a problem reading the stream.
protected ContentHandler.ByteOrderMark getByteOrderMark(URI uri,
java.io.InputStream inputStream,
java.util.Map<?,?> options,
java.util.Map<java.lang.Object,java.lang.Object> context)
throws java.io.IOException
uri - the URI of the input stream.inputStream - the input stream to scan.options - any options to influence the behavior; this base implementation ignores this.context - the cache for fetching and storing a previous computation of the byte order marker; this base implementation caches ContentHandler.BYTE_ORDER_MARK_PROPERTY.
java.io.IOException
