DOMInputImpl (Red Hat JBoss Enterprise Application Platform 7.2.0.GA public API)

java.lang.Object
- org.apache.xerces.dom.DOMInputImpl

All Implemented Interfaces:

LSInput
```
public class DOMInputImpl
extends Object
implements LSInput
```
This Class DOMInputImpl represents a single input source for an XML entity.
This Class allows an application to encapsulate information about an input source in a single object, which may include a public identifier, a system identifier, a byte stream (possibly with a specified encoding), and/or a character stream.
The exact definitions of a byte stream and a character stream are binding dependent.
There are two places that the application will deliver this input source to the parser: as the argument to the parse method, or as the return value of the DOMResourceResolver.resolveEntity method.
The DOMParser will use the LSInput object to determine how to read XML input. If there is a character stream available, the parser will read that stream directly; if not, the parser will use a byte stream, if available; if neither a character stream nor a byte stream is available, the parser will attempt to open a URI connection to the resource identified by the system identifier.
An LSInput object belongs to the application: the parser shall never modify it in any way (it may modify a copy if necessary). Eventhough all attributes in this interface are writable the DOM implementation is expected to never mutate a LSInput.

  - getByteStream
```
public InputStream getByteStream()
```
    An attribute of a language-binding dependent type that represents a stream of bytes.
    The parser will ignore this if there is also a character stream specified, but it will use a byte stream in preference to opening a URI connection itself.
    If the application knows the character encoding of the byte stream, it should set the encoding property. Setting the encoding in this way will override any encoding specified in the XML declaration itself.
    
    Specified by:
    
    getByteStream in interface LSInput
  - setByteStream
```
public void setByteStream(InputStream byteStream)
```
    An attribute of a language-binding dependent type that represents a stream of bytes.
    The parser will ignore this if there is also a character stream specified, but it will use a byte stream in preference to opening a URI connection itself.
    If the application knows the character encoding of the byte stream, it should set the encoding property. Setting the encoding in this way will override any encoding specified in the XML declaration itself.
    
    Specified by:
    
    setByteStream in interface LSInput
  - getCharacterStream
```
public Reader getCharacterStream()
```
    An attribute of a language-binding dependent type that represents a stream of 16-bit units. Application must encode the stream using UTF-16 (defined in and Amendment 1 of ).
    If a character stream is specified, the parser will ignore any byte stream and will not attempt to open a URI connection to the system identifier.
    
    Specified by:
    
    getCharacterStream in interface LSInput
  - setCharacterStream
```
public void setCharacterStream(Reader characterStream)
```
    An attribute of a language-binding dependent type that represents a stream of 16-bit units. Application must encode the stream using UTF-16 (defined in and Amendment 1 of ).
    If a character stream is specified, the parser will ignore any byte stream and will not attempt to open a URI connection to the system identifier.
    
    Specified by:
    
    setCharacterStream in interface LSInput
  - getStringData
```
public String getStringData()
```
    A string attribute that represents a sequence of 16 bit units (utf-16 encoded characters).
    If string data is available in the input source, the parser will ignore the character stream and the byte stream and will not attempt to open a URI connection to the system identifier.
    
    Specified by:
    
    getStringData in interface LSInput
  - setStringData
```
public void setStringData(String stringData)
```
    A string attribute that represents a sequence of 16 bit units (utf-16 encoded characters).
    If string data is available in the input source, the parser will ignore the character stream and the byte stream and will not attempt to open a URI connection to the system identifier.
    
    Specified by:
    
    setStringData in interface LSInput
  - getEncoding
```
public String getEncoding()
```
    The character encoding, if known. The encoding must be a string acceptable for an XML encoding declaration ( section 4.3.3 "Character Encoding in Entities").
    This attribute has no effect when the application provides a character stream. For other sources of input, an encoding specified by means of this attribute will override any encoding specified in the XML claration or the Text Declaration, or an encoding obtained from a higher level protocol, such as HTTP .
    
    Specified by:
    
    getEncoding in interface LSInput
  - setEncoding
```
public void setEncoding(String encoding)
```
    The character encoding, if known. The encoding must be a string acceptable for an XML encoding declaration ( section 4.3.3 "Character Encoding in Entities").
    This attribute has no effect when the application provides a character stream. For other sources of input, an encoding specified by means of this attribute will override any encoding specified in the XML claration or the Text Declaration, or an encoding obtained from a higher level protocol, such as HTTP .
    
    Specified by:
    
    setEncoding in interface LSInput
  - getPublicId
```
public String getPublicId()
```
    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.
    
    Specified by:
    
    getPublicId in interface LSInput
  - setPublicId
```
public void setPublicId(String publicId)
```
    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.
    
    Specified by:
    
    setPublicId in interface LSInput
  - getSystemId
```
public String getSystemId()
```
    The system identifier, a URI reference , for this input source. The system identifier is optional if there is a byte stream or a character stream, but it is still useful to provide one, since the application can use it to resolve relative URIs and can include it in error messages and warnings (the parser will attempt to fetch the ressource identifier by the URI reference only if there is no byte stream or character stream specified).
    If the application knows the character encoding of the object pointed to by the system identifier, it can register the encoding by setting the encoding attribute.
    If the system ID is a relative URI reference (see section 5 in ), the behavior is implementation dependent.
    
    Specified by:
    
    getSystemId in interface LSInput
  - setSystemId
```
public void setSystemId(String systemId)
```
    The system identifier, a URI reference , for this input source. The system identifier is optional if there is a byte stream or a character stream, but it is still useful to provide one, since the application can use it to resolve relative URIs and can include it in error messages and warnings (the parser will attempt to fetch the ressource identifier by the URI reference only if there is no byte stream or character stream specified).
    If the application knows the character encoding of the object pointed to by the system identifier, it can register the encoding by setting the encoding attribute.
    If the system ID is a relative URI reference (see section 5 in ), the behavior is implementation dependent.
    
    Specified by:
    
    setSystemId in interface LSInput
  - getBaseURI
```
public String getBaseURI()
```
    The base URI to be used (see section 5.1.4 in ) for resolving relative URIs to absolute URIs. If the baseURI is itself a relative URI, the behavior is implementation dependent.
    
    Specified by:
    
    getBaseURI in interface LSInput
  - setBaseURI
```
public void setBaseURI(String baseURI)
```
    The base URI to be used (see section 5.1.4 in ) for resolving relative URIs to absolute URIs. If the baseURI is itself a relative URI, the behavior is implementation dependent.
    
    Specified by:
    
    setBaseURI in interface LSInput
  - getCertifiedText
```
public boolean getCertifiedText()
```
    If set to true, assume that the input is certified (see section 2.13 in [XML 1.1]) when parsing [XML 1.1].
    
    Specified by:
    
    getCertifiedText in interface LSInput
  - setCertifiedText
```
public void setCertifiedText(boolean certifiedText)
```
    If set to true, assume that the input is certified (see section 2.13 in [XML 1.1]) when parsing [XML 1.1].
