* the pair is:
* OVERFLOW_PAGE_NUMBER OVFLPAGE
*
* PARTIAL_KEY This must be the first key/data pair on a page
* and implies that page contains only a partial key.
* That is, the key is too big to fit on a single page
* so it starts on this page and continues on the next.
* The format of the page is:
* KEY_OFF PARTIAL_KEY OVFL_PAGENO OVFLPAGE
*
* KEY_OFF -- offset of the beginning of the key
* PARTIAL_KEY -- 1
* OVFL_PAGENO - page number of the next overflow page
* OVFLPAGE -- 0
*
* FULL_KEY This must be the first key/data pair on the page. It
* is used in two cases.
*
* Case 1:
* There is a complete key on the page but no data
* (because it wouldn't fit). The next page contains
* the data.
*
* Page format it:
* KEY_OFF FULL_KEY OVFL_PAGENO OVFL_PAGE
*
* KEY_OFF -- offset of the beginning of the key
* FULL_KEY -- 2
* OVFL_PAGENO - page number of the next overflow page
* OVFLPAGE -- 0
*
* Case 2:
* This page contains no key, but part of a large
* data field, which is continued on the next page.
*
* Page format it:
* DATA_OFF FULL_KEY OVFL_PAGENO OVFL_PAGE
*
* KEY_OFF -- offset of the beginning of the data on
* this page
* FULL_KEY -- 2
* OVFL_PAGENO - page number of the next overflow page
* OVFLPAGE -- 0
*
* FULL_KEY_DATA
* This must be the first key/data pair on the page.
* There are two cases:
*
* Case 1:
* This page contains a key and the beginning of the
* data field, but the data field is continued on the
* next page.
*
* Page format is:
* KEY_OFF FULL_KEY_DATA OVFL_PAGENO DATA_OFF
*
* KEY_OFF -- offset of the beginning of the key
* FULL_KEY_DATA -- 3
* OVFL_PAGENO - page number of the next overflow page
* DATA_OFF -- offset of the beginning of the data
*
* Case 2:
* This page contains the last page of a big data pair.
* There is no key, only the tail end of the data
* on this page.
*
* Page format is:
* DATA_OFF FULL_KEY_DATA <OVFL_PAGENO> <OVFLPAGE>
*
* DATA_OFF -- offset of the beginning of the data on
* this page
* FULL_KEY_DATA -- 3
* OVFL_PAGENO - page number of the next overflow page
* OVFLPAGE -- 0
*
* OVFL_PAGENO and OVFLPAGE are optional (they are
* not present if there is no next page).

* linked so that an arbitrary element can be removed without a need to

/**
* Create a JavaScript function object from a Java method.
*
* <p>The <code>member</code> argument must be either a java.lang.reflect.Method
* or a java.lang.reflect.Constructor and must match one of two forms.<p>
*
* The first form is a member with zero or more parameters
* of the following types: Object, String, boolean, Scriptable,
* byte, short, int, float, or double. The Long type is not supported
* because the double representation of a long (which is the
* EMCA-mandated storage type for Numbers) may lose precision.
* If the member is a Method, the return value must be void or one
* of the types allowed for parameters.<p>
*
* The runtime will perform appropriate conversions based
* upon the type of the parameter. A parameter type of
* Object specifies that no conversions are to be done. A parameter
* of type String will use Context.toString to convert arguments.
* Similarly, parameters of type double, boolean, and Scriptable
* will cause Context.toNumber, Context.toBoolean, and
* Context.toObject, respectively, to be called.<p>
*
* If the method is not static, the Java 'this' value will
* correspond to the JavaScript 'this' value. Any attempt
* to call the function with a 'this' value that is not
* of the right Java type will result in an error.<p>
*
* The second form is the variable arguments (or "varargs")
* form. If the FunctionObject will be used as a constructor,
* the member must have the following parameters
* <pre>
* (Context cx, Object[] args, Function ctorObj,
* boolean inNewExpr)</pre>
* and if it is a Method, be static and return an Object result.<p>
*
* Otherwise, if the FunctionObject will <i>not</i> be used to define a
* constructor, the member must be a static Method with parameters
* (Context cx, Scriptable thisObj, Object[] args,
* Function funObj) </pre>
* <pre>
* and an Object result.<p>
*
* When the function varargs form is called as part of a function call,
* the <code>args</code> parameter contains the
* arguments, with <code>thisObj</code>
* set to the JavaScript 'this' value. <code>funObj</code>
* is the function object for the invoked function.<p>
*
* When the constructor varargs form is called or invoked while evaluating
* a <code>new</code> expression, <code>args</code> contains the
* arguments, <code>ctorObj</code> refers to this FunctionObject, and
* <code>inNewExpr</code> is true if and only if a <code>new</code>
* expression caused the call. This supports defining a function that
* has different behavior when called as a constructor than when
* invoked as a normal function call. (For example, the Boolean
* constructor, when called as a function,
* will convert to boolean rather than creating a new object.)<p>
*
* @param name the name of the function
* @param methodOrConstructor a java.lang.reflect.Method or a java.lang.reflect.Constructor
* that defines the object
* @param scope enclosing scope of function
