## Detailed Description

A single input source for an XML entity.

This class encapsulates information about an input source in a single object, which may include a public identifier or a system identifier

There are two places that the application will deliver this input source to the parser: as the argument to the Parser::parse method, or as the return value of the EntityResolver::resolveEntity method.

InputSource is never used directly, but is the base class for a number of derived classes for particular types of input sources. Derivatives are provided (in the framework/ directory) for URL input sources, memory buffer input sources, and so on.

When it is time to parse the input described by an input source, it will be asked to create a binary stream for that source. That stream will be used to input the data of the source. The derived class provides the implementation of the makeStream() method, and provides a type of stream of the correct type for the input source it represents.

An InputSource object belongs to the application: the parser never modifies them in any way. They are always passed by const reference so the parser will make a copy of any input sources that it must keep around beyond the call.

## Member Function Documentation

## ◆ getEncoding()

const XMLCh * InputSource::getEncoding | ( |  | ) | const
| virtual

An input source can be set to force the parser to assume a particular encoding for the data that input source represents, via the setEncoding() method.

This method returns name of the encoding that is to be forced. If the encoding has never been forced, it returns a null pointer.

Returns
  The forced encoding, or null if none was supplied.

See also
  setEncoding

Reimplemented in Wrapper4DOMLSInput.

## ◆ getIssueFatalErrorIfNotFound()

bool InputSource::getIssueFatalErrorIfNotFound | ( |  | ) | const
| virtual

Get the flag that indicates if the parser should issue fatal error if this input source is not found.

Returns
  True if the parser should issue fatal error if this input source is not found. False if the parser issue warning message instead.

See also
  setIssueFatalErrorIfNotFound

Reimplemented in Wrapper4DOMLSInput.

## ◆ getMemoryManager()

MemoryManager * InputSource::getMemoryManager | ( |  | ) | const

## ◆ getPublicId()

const XMLCh * InputSource::getPublicId | ( |  | ) | const
| virtual

Get the public identifier for this input source.

Returns
  The public identifier, or null if none was supplied.

See also
  setPublicId

Reimplemented in Wrapper4DOMLSInput.

## ◆ getSystemId()

const XMLCh * InputSource::getSystemId | ( |  | ) | const
| virtual

Get the system identifier for this input source.

If the system ID is a URL, it will be fully resolved.

Returns
  The system identifier.

See also
  setSystemId

Reimplemented in Wrapper4DOMLSInput.

## ◆ makeStream()

virtual BinInputStream * InputSource::makeStream | ( |  | ) | const
| pure virtual

Makes the byte stream for this input source.

The derived class must create and return a binary input stream of an appropriate type for its kind of data source. The returned stream must be dynamically allocated and becomes the parser's property.

See also
  BinInputStream

Implemented in LocalFileInputSource, MemBufInputSource, StdInInputSource, URLInputSource, and Wrapper4DOMLSInput.

## ◆ setEncoding()

virtual void InputSource::setEncoding | ( | const XMLCh *const | encodingStr | ) |
| virtual

Set the encoding which will be required for use with the XML text read via a stream opened by this input source.

This is usually not set, allowing the encoding to be sensed in the usual XML way. However, in some cases, the encoding in the file is known to be incorrect because of intermediate transcoding, for instance encapsulation within a MIME document.

Parameters

  encodingStr | The name of the encoding to force.

Reimplemented in Wrapper4DOMLSInput.

## ◆ setIssueFatalErrorIfNotFound()

void InputSource::setIssueFatalErrorIfNotFound | ( | const bool | flag | ) |
| virtual

Indicates if the parser should issue fatal error if this input source is not found.

If set to false, the parser issue warning message instead.

Parameters

  flag | True if the parser should issue fatal error if this input source is not found. If set to false, the parser issue warning message instead. (Default: true)

See also
  getIssueFatalErrorIfNotFound

Reimplemented in Wrapper4DOMLSInput.

## ◆ setPublicId()

virtual void InputSource::setPublicId | ( | const XMLCh *const | publicId | ) |
| virtual

Set the public identifier for this input source.

The public identifier is always optional: if the application writer includes one, it will be provided as part of the location information.

Parameters

  publicId | The public identifier as a string.

See also
  Locator::getPublicId
  SAXParseException::getPublicId
  getPublicId

Reimplemented in Wrapper4DOMLSInput.

## ◆ setSystemId()

virtual void InputSource::setSystemId | ( | const XMLCh *const | systemId | ) |
| virtual

Set the system identifier for this input source.

Set the system identifier for this input source.

The system id is always required. The public id may be used to map to another system id, but the system id must always be present as a fall back.

If the system ID is a URL, it must be fully resolved.

Parameters

  systemId | The system identifier as a string.

  Locator::getSystemId
  SAXParseException::getSystemId
