ObjectParser
public class Parser
Main interface to the geotools xml parser.
Configuration
javadocs for instructions on how
to customize schema resolution. This is often desirable in the case that
the instance document being parsed contains invalid uri's in schema imports
and includes.

The object returned from the parse is the object which has been bound to the root element of the document. This method should only be called once for a single instance document.

public void setStrict(boolean strict)
When set to true
, this will cause the parser to operate in
a strict mode, which means that xml being parsed must be exactly correct
with respect to the schema it references.
Some examples of cases in which the parser will throw an exception while operating in strict mode:
strict
- The strict flag.public void setValidating(boolean validating)
validating
- Validation flag, true
to validate, otherwise false
public boolean isValidating()
public void setFailOnValidationError(boolean fail)
When this flag is set, the parser will throw an exception when it encounters
a validation error. Otherise the error will be stored, retreivable from
getValidationErrors()
.
The default behavior is to set this flag to false
. So client
code should explicitly set this flag if it is desired that the exception
be thrown when the validation error occurs.
fail
- failure flag, true
to fail, otherwise false
public boolean isFailOnValidationError()
public List getValidationErrors()
public void validate(InputStream in) throws IOException, SAXException, ParserConfigurationException
Clients should call getValidationErrors()
after this method to
retrieve any validation errors that occurred. Clients do not need to call
setValidating(boolean)
when using this method to validate.
This method does not do any of the work done by parse(InputSource)
, it
only validates.

public XSDSchema[] getSchemas()
public NamespaceSupport getNamespaces()
Clients may register additional namespace mappings. This is useful when an application whishes to provide some "default" namespace mappings.
Clients should register namespace mappings in the current "context", ie
do not call NamespaceSupport.pushContext()
. Example:
Parser parser = new Parser( ... );
parser.getNamespaces().declarePrefix( "foo", "http://www.foo.com" );
...
