Class GPEParser

java.lang.Object

org.gvsig.gpe.lib.impl.parser.GPEParser

All Implemented Interfaces:

IGPEParser

Direct Known Subclasses:

GPEXmlParser

public abstract class GPEParser
extends java.lang.Object
implements IGPEParser

This class has to be inherited by all the classes that implements a parser for a geographical format. IT has methods to indicate the formats and the versions that is able to parse.

Method Detail

parse

public void parse(IGPEContentHandlerInmGeom contents,
                  IGPEErrorHandler errors,
                  java.net.URI uri)

Method to parse a file. It cannot to throw any exception and it cannot to return any value. In a future it could be implemented like a independent thread

Specified by:

parse in interface IGPEParser

Parameters:

contents - Application ContentHandler

errors - Application ErrorsHandler

uri - File to open

Throws:

java.lang.Exception

parseURI

protected abstract void parseURI()

Parses the file from a URI

parse

                  IGPEErrorHandler errors,
                  java.io.InputStream is)

Method to parse an InputStream. It cannot to throw any exception and it cannot to return any value. In a future it could be implemented like a independent thread

Specified by:

parse in interface IGPEParser

Parameters:

contents - Application ContentHandler

errors - Application ErrorsHandler

is - The input stream

Throws:

java.lang.Exception

parseStream

protected abstract void parseStream()

Parses the file from an input stream

accept

public abstract boolean accept(java.net.URI uri)

Return if the driver can open the file

Specified by:

accept in interface IGPEParser

Parameters:

uri - File to open

Returns:

True if the driver is able to open it

accept

public abstract boolean accept(java.io.File file)

Return if the driver can open the file

Parameters:

uri - File to open

Returns:

True if the driver is able to open it

getFormat

public abstract java.lang.String getFormat()

Return the format that the driver is able to read

Specified by:

getFormat in interface IGPEParser

Returns:

getContentHandler

public IGPEContentHandlerInmGeom getContentHandler()

Specified by:

getContentHandler in interface IGPEParser

Returns:

the contentHandler

getErrorHandler

public IGPEErrorHandler getErrorHandler()

getName in interface IGPEParser

Returns:

the name

getInputStream

protected java.io.InputStream getInputStream()

Returns:

the is

setInputStream

protected void setInputStream(java.io.InputStream is)

Deprecated. to avoid temporal coupling

We need to find a better way to reuse or coupling parsers. This method was introduced for the SLD parsing to grab a single geometry from a filter.

Parameters:

is - the is to set

setErrorHandler

public void setErrorHandler(IGPEErrorHandler errorHandler)

Specified by:

setErrorHandler in interface IGPEParser

Parameters:

errorHandler - the errorHandler to set

setContentHandler

public void setContentHandler(IGPEContentHandlerInmGeom contentHandler)

Specified by:

setContentHandler in interface IGPEParser

Parameters:

contentHandler - the contentHandler to set

getGpeManager

public GPEManager getGpeManager()

Returns:

the gpeManager
