Constructor Detail

DefaultDataTable

public DefaultDataTable()

Creates a new table.

DefaultDataTable

public DefaultDataTable(LValue[][] array)

Method Detail

clone

public Object clone()

evaluate

public TypeValuePair evaluate()

getChildValues

public LValue[] getChildValues()

Returns any dependent lvalues (parameters and operands, mostly).

Returns:

getColumnName

public String getColumnName(int column)

getParsePosition

public ParsePosition getParsePosition()

getValueAt

public LValue getValueAt(int row, int column)

getValueType

public Type getValueType()

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

Returns:

initialize

public void initialize(FormulaContext context)

isConstant

public boolean isConstant()

Checks whether the LValue is constant. Constant lvalues always return the same value.

Returns:

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.

setParsePosition

public void setParsePosition(ParsePosition parsePosition)
