visad.Tuple
public class Tuple
Tuple is the general VisAD data class for vectors.
Tuple objects are immutable in the sense that the sequence of Data
objects cannot be modified; Tuple objects are mutable, however, in the
sense that a contained Data
object might be mutable (e.g. it might
be a Field
with modifiable range values).

Constructor Summary | |
---|---|
Tuple(Data[] datums)
construct a Tuple object from an array of Data objects; this constructs its MathType from the MathTypes of the data array; components are copies of data |
|
Tuple(Data[] datums,
boolean copy)
construct a Tuple object from an array of Data objects; this constructs its MathType from the MathTypes of the data array; only copy data if copy == true |
|
Tuple(TupleType type)
construct a Tuple object with missing value |
|
Tuple(TupleType type,
Data[] datums)
construct a Tuple object from a type and an array of Data objects |
|
Tuple(TupleType type,
Data[] datums,
boolean copy)
construct a Tuple object from a type and an array of Data objects |
Method Summary | |
---|---|
Data |
__getitem__(int index)
A wrapper around getComponent for JPython. |
int |
__len__()
A wrapper around getLength for JPython. |
Data |
adjustSamplingError(Data error,
int error_mode)
return a Tuple that clones this, except its ErrorEstimate-s are adjusted for sampling errors in error |
Data |
binary(Data data,
int op,
MathType new_type,
int sampling_mode,
int error_mode)
general binary operation between this and data; op may be Data.ADD, Data.SUBTRACT, etc; these include all binary operations defined for Java primitive data types; new_type is the MathType of the result; sampling_mode may be Data.NEAREST_NEIGHBOR or Data.WEIGHTED_AVERAGE; error_mode may be Data.INDEPENDENT, Data.DEPENDENT or Data.NO_ERRORS |
static TupleType |
buildTupleType(Data[] datums)
make a TupleType for an array of Data |
java.lang.Object |
clone()
Clones this instance. |
DataShadow |
computeRanges(ShadowType type,
DataShadow shadow)
recursive version of computeRanges; would like 'default' visibility here, but must be declared 'public' because it is defined in the Data interface |
boolean |
equals(java.lang.Object obj)
Indicates if this Tuple is identical to an object. |
Data |
getComponent(int i)
Returns a component of this instance. |
Data[] |
getComponents()
Returns the components that constitute this instance. |
int |
getDimension()
return number of components |
int |
getLength()
Return the number of components of the Tuple |
Real[] |
getRealComponents()
|
int |
hashCode()
Returns the hash code of this object. |
boolean |
isMissing()
a method to tell whether data object has a missing value |
java.lang.String |
longString(java.lang.String pre)
generates a longer string than generated by toString, indented by pre (a string of blanks) |
static Tuple |
makeTuple(Data[] datums)
|
Data |
unary(int op,
MathType new_type,
int sampling_mode,
int error_mode)
general unary operation; operation may be Data.ABS, Data.ACOS, etc; these include all unary operations defined for Java primitive data types; new_type is the MathType of the result; sampling_mode may be Data.NEAREST_NEIGHBOR or Data.WEIGHTED_AVERAGE; error_mode may be Data.INDEPENDENT, Data.DEPENDENT or Data.NO_ERRORS |
