Class PatternParser

A XMLReader document handler to read and parse hyphenation patterns from a XML file.

LUCENENET: This class has been refactored from its Java counterpart to use XmlReader rather than a SAX parser.

Syntax

public class PatternParser

Constructors

PatternParser()

Declaration

public PatternParser()

PatternParser(IPatternConsumer)

Declaration

public PatternParser(IPatternConsumer consumer)

Parameters

Type	Name	Description
IPatternConsumer	consumer

Properties

Consumer

Declaration

public virtual IPatternConsumer Consumer { get; set; }

Property Value

Type	Description
IPatternConsumer

Methods

Characters(Char[], Int32, Int32)

Receive notification of character data.

The Parser will call this method to report each chunk of character data. Parsers may return all contiguous character data in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity so that the Locator provides useful information.

The application must not attempt to read from the array outside of the specified range.

Declaration

public virtual void Characters(char[] ch, int start, int length)

Parameters

Type	Name	Description
System.Char[]	ch
System.Int32	start
System.Int32	length

EndElement(String, String, String)

Receive notification of the end of an element.

The parser will invoke this method at the end of every element in the XML document; there will be a corresponding StartElement(String, String, String, IDictionary<String, String>) event for every EndElement(String, String, String) event (even when the element is empty).

Declaration

public virtual void EndElement(string uri, string local, string raw)

Parameters

Type	Name	Description
System.String	uri	the Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed
System.String	local	the local name (without prefix), or the empty string if Namespace processing is not being performed
System.String	raw

GetExceptionWord<T1>(IList<T1>)

Declaration

protected virtual string GetExceptionWord<T1>(IList<T1> ex)

Parameters

Type	Name	Description
System.Collections.Generic.IList<T1>	ex

Returns

Type	Description
System.String

Type Parameters

Name	Description
T1

GetInterletterValues(String)

Declaration

protected static string GetInterletterValues(string pat)

Parameters

Type	Name	Description
System.String	pat

Returns

Type	Description
System.String

GetPattern(String)

Declaration

protected static string GetPattern(string word)

Parameters

Type	Name	Description
System.String	word

Returns

Type	Description
System.String

NormalizeException<T1>(IList<T1>)

Declaration

protected virtual IList<object> NormalizeException<T1>(IList<T1> ex)

Parameters

Type	Name	Description
System.Collections.Generic.IList<T1>	ex

Returns

Type	Description
System.Collections.Generic.IList<System.Object>

Type Parameters

Name	Description
T1

Parse(FileInfo)

Parses a hyphenation pattern file.

Declaration

public virtual void Parse(FileInfo file)

Parameters

Type	Name	Description
System.IO.FileInfo	file	a System.IO.FileInfo object representing the file

Exceptions

Type	Condition
System.IO.IOException	In case of an exception while parsing

Parse(FileInfo, Encoding)

Parses a hyphenation pattern file.

Declaration

public virtual void Parse(FileInfo file, Encoding encoding)

Parameters

Type	Name	Description
System.IO.FileInfo	file	a System.IO.FileInfo object representing the file
System.Text.Encoding	encoding	The character encoding to use

Exceptions

Type	Condition
System.IO.IOException	In case of an exception while parsing

Parse(Stream)

Parses a hyphenation pattern file.

Declaration

public virtual void Parse(Stream xmlStream)

Parameters

Type	Name	Description
System.IO.Stream	xmlStream	The stream containing the XML data. The PatternParser scans the first bytes of the stream looking for a byte order mark or other sign of encoding. When encoding is determined, the encoding is used to continue reading the stream, and processing continues parsing the input as a stream of (Unicode) characters.

Exceptions

Type	Condition
System.IO.IOException	In case of an exception while parsing

Parse(String)

Parses a hyphenation pattern file.

Declaration

public virtual void Parse(string path)

Parameters

Type	Name	Description
System.String	path	The complete file path to be read.

Exceptions

Type	Condition
System.IO.IOException	In case of an exception while parsing

Parse(String, Encoding)

Parses a hyphenation pattern file.

Declaration

public virtual void Parse(string path, Encoding encoding)

Parameters

Type	Name	Description
System.String	path	The complete file path to be read.
System.Text.Encoding	encoding	The character encoding to use

Exceptions

Type	Condition
System.IO.IOException	In case of an exception while parsing

Parse(XmlReader)

Parses a hyphenation pattern file.

Declaration

public virtual void Parse(XmlReader source)

Parameters

Type	Name	Description
System.Xml.XmlReader	source	System.Xml.XmlReader input source for the file

Exceptions

Type	Condition
System.IO.IOException	In case of an exception while parsing

ReadToken(StringBuilder)

Declaration

protected virtual string ReadToken(StringBuilder chars)

Parameters

Type	Name	Description
System.Text.StringBuilder	chars

Returns

Type	Description
System.String

StartElement(String, String, String, IDictionary<String, String>)

Receive notification of the beginning of an element.

The Parser will invoke this method at the beginning of every element in the XML document; there will be a corresponding EndElement(String, String, String) event for every StartElement(String, String, String, IDictionary<String, String>) event (even when the element is empty). All of the element's content will be reported, in order, before the corresponding endElement event.

Declaration

public virtual void StartElement(string uri, string local, string raw, IDictionary<string, string> attrs)

Parameters

Type	Name	Description
System.String	uri	the Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed
System.String	local	the local name (without prefix), or the empty string if Namespace processing is not being performed
System.String	raw
System.Collections.Generic.IDictionary<System.String, System.String>	attrs	the attributes attached to the element. If there are no attributes, it shall be an empty Attributes object. The value of this object after startElement returns is undefined
