public abstract class DocumentBuilderFactory
extends java.lang.Object

The `DocumentBuilderFactory` defines a factory API that enables applications to configure and obtain a parser to parse XML documents into a DOM Document tree.

Constructor Summary
`protected` | `DocumentBuilderFactory()` Implementors of this abstract class must provide their own public no-argument constructor in order for the static `newInstance()` method to work correctly.

Method Summary
`boolean` | `isNamespaceAware()` Indicates if this `DocumentBuilderFactory` is configured to produce parsers that are namespace aware or not.
`boolean` | `isValidating()` Indicates if this `DocumentBuilderFactory` is configured to produce parsers that validate XML documents as they are parsed.
`abstract DocumentBuilder` | `newDocumentBuilder()` Returns a new configured instance of type `DocumentBuilder`.
`static DocumentBuilderFactory` | `newInstance()` Returns a new instance of a `DocumentBuilderFactory`.
`void` | `setNamespaceAware(boolean aware)` Configuration method that specifies whether the parsers created by this factory are required to provide XML namespace support or not.
`void` | `setValidating(boolean validating)` Configuration method whether specifies if the parsers created by this factory are required to validate the XML documents that they parse.

Constructor Detail

### DocumentBuilderFactory

    protected DocumentBuilderFactory()

  Implementors of this abstract class must provide their own public no-argument constructor in order for the static `newInstance()` method to work correctly.
  Application programmers should be able to instantiate an implementation of this abstract class directly if they want to use a specfic implementation of this API without using the static newInstance method to obtain the configured or platform default implementation.

Method Detail

### newInstance

    public static DocumentBuilderFactory newInstance()

  Returns a new instance of a `DocumentBuilderFactory`.
  The implementation of the `DocumentBuilderFactory` returned depends on the setting of the `javax.xml.parsers.DocumentBuilderFactory` property or, if the property is not set, a platform specific default.
  Throws:
    FactoryConfigurationError - If the class implementing the factory cannot be found or instantiated. An `Error` is thrown instead of an exception because the application is not expected to handle or recover from such events.

### newDocumentBuilder

    public abstract DocumentBuilder newDocumentBuilder()
                                                throws ParserConfigurationException

  Returns a new configured instance of type `DocumentBuilder`.
  Throws:
    ParserConfigurationException - If the `DocumentBuilder` instance cannot be created with the requested configuration.

### setNamespaceAware

    public void setNamespaceAware(boolean aware)

  Configuration method that specifies whether the parsers created by this factory are required to provide XML namespace support or not.
  NOTE: if a parser cannot be created by this factory that satisfies the requested namespace awareness value, a `ParserConfigurationException` will be thrown when the program attempts to aquire the parser calling the `newDocumentBuilder()` method.

### setValidating

    public void setValidating(boolean validating)

  Configuration method whether specifies if the parsers created by this factory are required to validate the XML documents that they parse.
  NOTE: if a parser cannot be created by this factory that satisfies the requested validation capacity, a `ParserConfigurationException` will be thrown when the application attempts to aquire the parser via the `newDocumentBuilder()` method.

### isNamespaceAware

    public boolean isNamespaceAware()

  Indicates if this `DocumentBuilderFactory` is configured to produce parsers that are namespace aware or not.

### isValidating

    public boolean isValidating()

  Indicates if this `DocumentBuilderFactory` is configured to produce parsers that validate XML documents as they are parsed.
