public static String toSPARQL(Value theValue)

Return the SPARQL query string rendering of the Value

Parameters:

Returns:

the value rendered in its SPARQL query string representation

public static StringBuilder toSPARQL(Value value,
 StringBuilder builder)

Append the SPARQL query string rendering of the Value to the supplied StringBuilder.

Parameters:

value - the value to render

builder - the StringBuilder to append to

escape

public static String escape(String theString)

Properly escape out any special characters in the query string. Replaces unescaped double quotes with \" and replaces slashes '\' which are not a valid escape sequence such as \t or \n with a double slash '\\' so they are unescaped correctly by a SPARQL parser.

Parameters:

theString - the query string to escape chars in

Returns:

the escaped query string
