Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`accept(Visitor visitor)`	`accept` is the method used in the Visitor Pattern.
`String`	`asXML()`	`asXML` returns the textual XML representation of this node.
`String`	`getName()`	`getName` returns the name of this node.
`short`	`getNodeType()`	Returns the code according to the type of node.
`String`	`getPath(Element context)`	Returns the relative XPath expression which will return a node set containing the given node such as a/b/@c.

`protected Map<String,String>`	`parseValues(String text)`	Parses the raw data of PI as a `Map`.
`boolean`	`removeValue(String name)`
`void`	`setName(String name)`	Sets the text data of this node or this method will throw an `UnsupportedOperationException` if it is read-only.
`void`	`setValue(String name, String value)`

public AbstractProcessingInstruction()
```
- Method Detail
  - getNodeType
```
public short getNodeType()
```
    Description copied from interface: Node
    
    Returns the code according to the type of node. This makes processing nodes polymorphically much easier as the switch statement can be used instead of multiple if (instanceof) statements.
    
    Specified by:
    
    getNodeType in interface Node
    
    Overrides:
    
    getNodeType in class AbstractNode
    
    Returns:
    
    a W3C DOM complient code for the node type such as ELEMENT_NODE or ATTRIBUTE_NODE
  - getPath
```
public String getPath(Element context)
```
    Description copied from interface: Node
    
    Returns the relative XPath expression which will return a node set containing the given node such as a/b/@c. No indexing will be used to restrict the path if multiple elements with the same name occur on the path.
    
    Specified by:
    
    getPath in interface Node
    
    Parameters:
    
    context - is the parent context from which the relative path should start. If the context is null or the context is not an ancestor of this node then the path will be absolute and start from the document and so begin with the '/' character.
    
    Returns:
    
    the XPath expression relative to the given context which will return a nodeset containing at least this node.
  - getUniquePath
```
public String getUniquePath(Element context)
```
    Description copied from interface: Node
    
    Returns the relative unique XPath expression from the given context which will return a nodeset of one node which is the current node. This method will use the XPath index operator to restrict the path if multiple elements with the same name occur on the path.
    
    Specified by:
    
    getUniquePath in interface Node
    
    Parameters:
    
    context - is the parent context from which the path should start. If the context is null or the context is not an ancestor of this node then the path will start from the document and so begin with the '/' character.
    
    Returns:
    
    the XPath expression relative to the given context which will return a nodeset containing just this node.
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - asXML
```
public String asXML()
```
    Description copied from interface: Node
    
    asXML returns the textual XML representation of this node.
    
    Specified by:
    
    asXML in interface Node
    
    Returns:
    
    the XML representation of this node
  - write
```
public void write(Writer writer)
           throws IOException
```
    Description copied from interface: Node
    
    write writes this node as the default XML notation for this node. If you wish to control the XML output (such as for pretty printing, changing the indentation policy etc.) then please use XMLWriter or its derivations.
    
    Specified by:
    
    write in interface Node
    
    Overrides:
    
    write in class AbstractNode
    
    Parameters:
    
    writer - is the Writer to output the XML to
    
    Throws:
    
    IOException - DOCUMENT ME!
  - accept
```
public void accept(Visitor visitor)
```
    Description copied from interface: Node
    
    accept is the method used in the Visitor Pattern.
    
    Specified by:
    
    accept in interface Node
    
    Parameters:
    
    visitor - is the visitor in the Visitor Pattern
  - setValue
```
public void setValue(String name,
                     String value)
```
    Specified by:
    
    setValue in interface ProcessingInstruction
  - setValues
```
public void setValues(Map<String,String> data)
```
    Specified by:
    
    setValues in interface ProcessingInstruction
  - getName
```
public String getName()
```
    Description copied from interface: Node
    
    getName returns the name of this node. This is the XML local name of the element, attribute, entity or processing instruction. For CDATA and Text nodes this method will return null.
    
    Specified by:
    
    getName in interface Node
    
    Overrides:
    
    getName in class AbstractNode
    
    Returns:
    
    the XML name of this node
  - setName
```
public void setName(String name)
```
    Description copied from interface: Node
    
    Sets the text data of this node or this method will throw an UnsupportedOperationException if it is read-only.
    
    Specified by:
    
    setName in interface Node
    
    Overrides:
    
    setName in class AbstractNode
    
    Parameters:
    
    name - is the new name of this node
  - removeValue
```
public boolean removeValue(String name)
```
    Specified by:
    
    removeValue in interface ProcessingInstruction
  - toString
```
protected String toString(Map<String,String> values)
```
    This will convert the Map to a string representation.
    
    Parameters:
    
    values - is a Map of PI data to convert
    
    Returns:
    
    DOCUMENT ME!
  - parseValues
```
protected Map<String,String> parseValues(String text)
```
    Parses the raw data of PI as a Map.
    
    Parameters:
    
    text - String PI data to parse
    
    Returns:
    
    DOCUMENT ME!
