JCInputStreamDataSource

public JCInputStreamDataSource(InputStream i)
                        throws IOException

This constructor takes the InputStream, reads in all the appropriate data and interprets it according to the default interpreter class.

Parameters:

i - InputStream object used to read the data

Throws:

IOException - An IOException will be thrown if there are any errors while reading in the data.

JCInputStreamDataSource

public JCInputStreamDataSource(InputStream i,
                               com.klg.jclass.chart.data.JCDataInterpreter p)
                        throws IOException

This constructor takes the InputStream, reads in all the appropriate data, and interprets it according to the specified interpreter class.

Parameters:

i - InputStream object used to read the data

p - Interpreter used to make sense of the data

Throws:

IOException - An IOException will be thrown if there are any errors while reading in the data.

JCInputStreamDataSource

public JCInputStreamDataSource(InputStream i,
                               com.klg.jclass.chart.data.JCDataInterpreter p,
                               String charsetName)
                        throws IOException

This constructor takes the InputStream, reads in all the appropriate data based on the given charset, and interprets it according to the specified interpreter class.

Parameters:

i - InputStream object used to read the data

p - Interpreter used to make sense of the data

charsetName - The name of a supported charset

Throws:

IOException - An IOException will be thrown if there are any errors while reading in the data.

JCInputStreamDataSource

protected JCInputStreamDataSource()
                           throws IOException

This constructor sets up a JCInputStreamDataSource class to use the default interpreter. It does not yet read or interpret any data.

Throws:

IOException - An IOException will be thrown if there are any errors while reading in the data.

JCInputStreamDataSource

protected JCInputStreamDataSource(com.klg.jclass.chart.data.JCDataInterpreter p)
                           throws IOException

This constructor sets up a JCInputStreamDataSource class to use the specified interpreter. It does not yet read or interpret any data.

Parameters:

p - the data interpreter to be used

Throws:

IOException - An IOException will be thrown if there are any errors while reading in the data.

JCInputStreamDataSource

protected JCInputStreamDataSource(com.klg.jclass.chart.data.JCDataInterpreter p,
                                  String charsetName)
                           throws IOException

This constructor sets up a JCInputStreamDataSource class to use the specified interpreter and charset. It does not yet read or interpret any data.

Parameters:

p - the data interpreter to be used

charsetName - The name of a supported charset

Throws:

IOException - An IOException will be thrown if there are any errors while reading in the data.

Method Detail

getInterpreter

public com.klg.jclass.chart.data.JCDataInterpreter getInterpreter()

Gets the interpreter

Returns:

The current interpreter

setInterpreter

public void setInterpreter(com.klg.jclass.chart.data.JCDataInterpreter interpreter)

Sets the interpreter

Parameters:

interpreter - The new interpreter

getCharsetName

public String getCharsetName()

Gets the name of the charset

Returns:

The name of the current charset

setCharsetName

public void setCharsetName(String charsetName)

Sets the name of the charset

Parameters:

charsetName - The name of a supported charset

ctor

protected void ctor(InputStream i)
             throws IOException

Parses the specified input stream and populates this data source. Provided because subclasses may need to set the stream up before they can call super() (for example, AppletDataSource).

Parameters:

i - the InputStream object to read data from

Throws:

IOException - An IOException will be thrown if there are any errors while reading in the data.

ctor

protected void ctor(Reader r)
             throws IOException

Version of ctor() that takes a Reader. Called by the other ctor() and for String input where you can't have an input stream. If no interpreter has been set, it determines the appropriate interpreter to use from the data in the reader.

Parameters:

r - the Reader object to read data from

Throws:

IOException - An IOException will be thrown if there are any errors while reading in the data.
