DefaultHandler

DefaultHandler()

characters

open fun characters(
    ch: CharArray!, 
    start: Int, 
    length: Int
): Unit

Receive notification of character data inside an element.

By default, do nothing. Application writers may override this method to take specific actions for each chunk of character data (such as adding the data to a node or buffer, or printing it to a file).

endDocument

open fun endDocument(): Unit

Receive notification of the end of the document.

By default, do nothing. Application writers may override this method in a subclass to take specific actions at the end of a document (such as finalising a tree or closing an output file).

endElement

open fun endElement(
    uri: String!, 
    localName: String!, 
    qName: String!
): Unit

Receive notification of the end of an element.

By default, do nothing. Application writers may override this method in a subclass to take specific actions at the end of each element (such as finalising a tree node or writing output to a file).

endPrefixMapping

open fun endPrefixMapping(prefix: String!): Unit

Receive notification of the end of a Namespace mapping.

By default, do nothing. Application writers may override this method in a subclass to take specific actions at the end of each prefix mapping.

error

open fun error(e: SAXParseException!): Unit

Receive notification of a recoverable parser error.

The default implementation does nothing. Application writers may override this method in a subclass to take specific actions for each error, such as inserting the message in a log file or printing it to the console.

fatalError

open fun fatalError(e: SAXParseException!): Unit

Report a fatal XML parsing error.

The default implementation throws a SAXParseException. Application writers may override this method in a subclass if they need to take specific actions for each fatal error (such as collecting all of the errors into a single report): in any case, the application must stop all regular processing when this method is invoked, since the document is no longer reliable, and the parser may no longer report parsing events.

ignorableWhitespace

open fun ignorableWhitespace(
    ch: CharArray!, 
    start: Int, 
    length: Int
): Unit

Receive notification of ignorable whitespace in element content.

By default, do nothing. Application writers may override this method to take specific actions for each chunk of ignorable whitespace (such as adding data to a node or buffer, or printing it to a file).

notationDecl

open fun notationDecl(
    name: String!, 
    publicId: String!, 
    systemId: String!
): Unit

Receive notification of a notation declaration.

By default, do nothing. Application writers may override this method in a subclass if they wish to keep track of the notations declared in a document.

processingInstruction

open fun processingInstruction(
    target: String!, 
    data: String!
): Unit

Receive notification of a processing instruction.

By default, do nothing. Application writers may override this method in a subclass to take specific actions for each processing instruction, such as setting status variables or invoking other methods.

resolveEntity

open fun resolveEntity(
    publicId: String!, 
    systemId: String!
): InputSource!

Resolve an external entity.

Always return null, so that the parser will use the system identifier provided in the XML document. This method implements the SAX default behaviour: application writers can override it in a subclass to do special translations such as catalog lookups or URI redirection.

setDocumentLocator

open fun setDocumentLocator(locator: Locator!): Unit

Receive a Locator object for document events.

By default, do nothing. Application writers may override this method in a subclass if they wish to store the locator for use with other document events.

skippedEntity

open fun skippedEntity(name: String!): Unit

Receive notification of a skipped entity.

By default, do nothing. Application writers may override this method in a subclass to take specific actions for each processing instruction, such as setting status variables or invoking other methods.

startDocument

open fun startDocument(): Unit

Receive notification of the beginning of the document.

By default, do nothing. Application writers may override this method in a subclass to take specific actions at the beginning of a document (such as allocating the root node of a tree or creating an output file).

startElement

open fun startElement(
    uri: String!, 
    localName: String!, 
    qName: String!, 
    attributes: Attributes!
): Unit

Receive notification of the start of an element.

By default, do nothing. Application writers may override this method in a subclass to take specific actions at the start of each element (such as allocating a new tree node or writing output to a file).

startPrefixMapping

open fun startPrefixMapping(
    prefix: String!, 
    uri: String!
): Unit

Receive notification of the start of a Namespace mapping.

By default, do nothing. Application writers may override this method in a subclass to take specific actions at the start of each Namespace prefix scope (such as storing the prefix mapping).

unparsedEntityDecl

open fun unparsedEntityDecl(
    name: String!, 
    publicId: String!, 
    systemId: String!, 
    notationName: String!
): Unit

Receive notification of an unparsed entity declaration.

By default, do nothing. Application writers may override this method in a subclass to keep track of the unparsed entities declared in a document.

warning

open fun warning(e: SAXParseException!): Unit

Receive notification of a parser warning.

The default implementation does nothing. Application writers may override this method in a subclass to take specific actions for each warning, such as inserting the message in a log file or printing it to the console.
