All Implemented Interfaces:
  java.lang.Cloneable

    public class SchemaValidate

extends XMLValidateTask

Validate XML Schema documents. This task validates XML schema documents. It requires an XML parser that handles the relevant SAX, Xerces or JAXP options. To resolve remote referencies, Ant may need its proxy set up, using the setproxy task. Hands off most of the work to its parent, `XMLValidateTask`

Since:
  Ant1.7

Constructor Detail

### SchemaValidate

    public SchemaValidate()

Method Detail

### init

    public void init()
              throws BuildException

  Called by the project to let the task initialize properly. The default implementation is a no-op.

  Overrides:
    `init` in class `XMLValidateTask`
  Throws:
    `BuildException` - if something goes wrong with the build

### enableXercesSchemaValidation

    public boolean enableXercesSchemaValidation()

  Turn on XSD support in Xerces.

  Returns:
    true on success, false on failure

### enableJAXP12SchemaValidation

    public boolean enableJAXP12SchemaValidation()

  Set schema attributes in a JAXP 1.2 engine.

  Returns:
    true on success, false on failure
  See Also:
    JAXP 1.2 Approved CHANGES

### addConfiguredSchema

    public void addConfiguredSchema(SchemaValidate.SchemaLocation location)

  add the schema

  Parameters:
    `location` - the schema location.
  Throws:
    `BuildException` - if there is no namespace, or if there already is a declaration of this schema with a different value

### setFullChecking

    public void setFullChecking(boolean fullChecking)

  enable full schema checking. Slower but better.

  Parameters:
    `fullChecking` - a `boolean` value.

### createAnonymousSchema

    protected void createAnonymousSchema()

  create a schema location to hold the anonymous schema

### setNoNamespaceURL

    public void setNoNamespaceURL(java.lang.String defaultSchemaURL)

  identify the URL of the default schema

  Parameters:
    `defaultSchemaURL` - the URL of the default schema.

### setNoNamespaceFile

    public void setNoNamespaceFile(java.io.File defaultSchemaFile)

  identify a file containing the default schema

  Parameters:
    `defaultSchemaFile` - the location of the default schema.

### setDisableDTD

    public void setDisableDTD(boolean disableDTD)

  flag to disable DTD support.

  Parameters:
    `disableDTD` - a `boolean` value.

### initValidator

    protected void initValidator()

  init the parser : load the parser class, and set features if necessary It is only after this that the reader is valid

  Overrides:
    `initValidator` in class `XMLValidateTask`
  Throws:
    `BuildException` - if something went wrong

### createDefaultReader

    protected org.xml.sax.XMLReader createDefaultReader()

  Create a reader if the use of the class did not specify another one. The reason to not use `JAXPUtils.getXMLReader()` was to create our own factory with our own options.

  Overrides:
    `createDefaultReader` in class `XMLValidateTask`
  Returns:
    a default XML parser

### addSchemaLocations

    protected void addSchemaLocations()

  build a string list of all schema locations, then set the relevant property.

### getNoNamespaceSchemaURL

    protected java.lang.String getNoNamespaceSchemaURL()

  get the URL of the no namespace schema

  Returns:
    the schema URL

### setFeatureIfSupported

    protected void setFeatureIfSupported(java.lang.String feature,
                                         boolean value)

  set a feature if it is supported, log at verbose level if not

    `value` - a `boolean` value.

### onSuccessfulValidation

    protected void onSuccessfulValidation(int fileProcessed)

  handler called on successful file validation.

  Overrides:
    `onSuccessfulValidation` in class `XMLValidateTask`
  Parameters:
    `fileProcessed` - number of files processed.
