Methods

Modifier and Type	Method and Description
protected XMLResource	createXMLResource() Creates a specialized XML resource for consuming just the root elements as well as the first nested element, if the root element is an XMI root element.
protected java.lang.String	getCharset(URI uri, java.io.InputStream inputStream, java.util.Map<?,?> options, java.util.Map<java.lang.Object,java.lang.Object> context) Returns the character set of the input stream; it's computed from the encoding specified in the XML content.

whether the given name and namespace represents a specialize XMI root element tag.

isXMINamespace

public static boolean isXMINamespace(java.lang.String namespace)

Returns whether the given namespace represents an XMI namespace.

Parameters:

namespace - the element namespace to consider.

Returns:

whether the given namespace represents an XMI namespace.

createXMLResource

protected XMLResource createXMLResource()

Creates a specialized XML resource for consuming just the root elements as well as the first nested element, if the root element is an XMI root element.

Returns:

an XML Resource for the root element and possibly the first nested element.

getCharset

protected java.lang.String getCharset(URI uri,
                          java.io.InputStream inputStream,
