Method Detail

parseStream

public final Enumeration<JIPTerm> parseStream(InputStream ins,
                               String streamName)

Returns an enumeration of terms contained in the specified input stream.

Parameters:

ins - the input stream to parse.

streamName - tha name of the stream (i.e. the name of the associated file)

public final Enumeration<JIPTerm> parseStream(InputStream ins,
                               String streamName,
                               String encoding)
                                       throws UnsupportedEncodingException

Returns an enumeration of terms contained in the specified input stream.

Parameters:

ins - the input stream to parse.

streamName - tha name of the stream (i.e. the name of the associated file)

Throws:

UnsupportedEncodingException

parseTerm

public final JIPTerm parseTerm(String strTerm)
                        throws JIPSyntaxErrorException

Parses the term passed in the parameter and returns a JIPTerm object that wraps the corresponding prolog term.
If the string passed in the parameter doesn't contains a valid prolog term it raises a JIPSyntaxErrorException.

Parameters:

strTerm - Term to be parsed. If the term doesn't end with a "dot" one is appended to it.

Returns:

a new JIPTerm object.

Throws:

JIPSyntaxErrorException

Returns:

the charset encoding

setEncoding

public void setEncoding(String encoding)

Parameters:

encoding - the charset encoding to set
