| getValue | | public Object getValue()(Code) | | Actual answer
the calculation result as a generic object |
| isCompatible | | public boolean isCompatible(CalcResult targetResults)(Code) | | Returns true if the target results is a compatible type with the current
results, with compatible meaning that the two results may be merged.
Parameters:
targetResults - the second CalcResult Object true if the targetResults can be merged with the current results |
| merge | | public CalcResult merge(CalcResult resultsToAdd)(Code) | | Returns the merged results of two CalcResult. The way in which the
results are merged is dependent on the type of the results added. A new
instance is created containing the merged results.
For example: merging two min functions would return the smaller of the
two values; merging a count and a sum would return an average.
Parameters:
resultsToAdd - the merged results |

the calculation result as an array (or null if not applicable) |
| toDouble | | public double toDouble()(Code) | | Access getValue as a double
the calculation result as a double (or 0 if not applicable) |
| toEnvelope | | public Envelope toEnvelope()(Code) | | Access getValue as an envelope
the calculation result as an envelope (or null if not applicable) |
| toFloat | | public float toFloat()(Code) | | Access getValue as a float
the calculation result as a float (or 0 if not applicable) |
| toGeometry | | public Geometry toGeometry()(Code) | | Access getValue as a geometry
the calculation result as a geometry (or null if not applicable) |
| toInt | | public int toInt()(Code) | | Access getValue as an int
the calculation result as a int (or 0 if not applicable)
throws:
IOException - |
| toList | | public List toList()(Code) | | Access getValue as a list
the calculation result as a list (or null if not applicable) |
| toLong | | public long toLong()(Code) | | Access getValue as a long
