/**
* Creates and initializes three new <code>HashMap</code> objects that map the strings returned by
* the SAX parser to <code>Integer</code> objects. The strings returned by the parser will match
* the strings that are array elements in this <code>XmlReaderContentHandler</code> object's
* <code>properties</code>, <code>colDef</code>, or <code>data</code> fields. For each array
* element in these fields, there is a corresponding constant defined. It is to these constants
* that the strings are mapped. In the <code>HashMap</code> objects, the string is the key, and
* the integer is the value.
*
* <p>The purpose of the mapping is to make comparisons faster. Because comparing numbers is more
* efficient than comparing strings, the strings returned by the parser are mapped to integers,
* which can then be used in a <code>switch</code> statement.
