Method Detail

getParsePosition

public ParsePosition getParsePosition()

Specified by:

getParsePosition in interface LValue

setParsePosition

public void setParsePosition(ParsePosition parsePosition)

getColumnName

public String getColumnName(int column)

Specified by:

getColumnName in interface DataTable

setObject

public void setObject(int row,
                      int column,
                      LValue object)

Sets the object for a cell in the table. The table is expanded if necessary.

Parameters:

row - the row index (zero-based).

column - the column index (zero-based).

object - the object.

getValueAt

public LValue getValueAt(int row,
                         int column)

Specified by:

getValueAt in interface DataTable

initialize

public void initialize(FormulaContext context)
                throws EvaluationException

Specified by:

initialize in interface LValue

Throws:

EvaluationException

evaluate

public TypeValuePair evaluate()
                       throws EvaluationException

Specified by:

evaluate in interface LValue

Throws:

EvaluationException

getAsArray

public ArrayCallback getAsArray()

clone

public Object clone()
             throws CloneNotSupportedException

Specified by:

clone in interface LValue

Overrides:

clone in class Object

Throws:

CloneNotSupportedException

getValueType

public Type getValueType()

Querying the value type is only valid *after* the value has been evaluated.

Specified by:

getValueType in interface LValue
