Class FunctionType

java.lang.Object

visad.MathType

visad.FunctionType

All Implemented Interfaces:

java.io.Serializable

public class FunctionType
extends MathType

FunctionType is the VisAD data type for functions.

A Function domain type may be either a RealType (for a function with domain = R) or a RealTupleType (for a function with domain = R^n for n > 0).

Constructor Detail

FunctionType

public FunctionType(MathType domain,
                    MathType range)
             throws VisADException

domain must be a RealType or a RealTupleType; range may be any MathType

Throws:

VisADException

Method Detail

getTextComponents

public TextType[] getTextComponents()

getTextIndices

public int[] getTextIndices()

getDomain

public RealTupleType getDomain()

if the domain passed to constructor was a RealType, getDomain returns a RealTupleType with that RealType as its single component

getRange

public MathType getRange()

getFlat

public boolean getFlat()

getReal

public boolean getReal()

getFlatRange

public RealTupleType getFlatRange()

getRealComponents

public RealType[] getRealComponents()

equals

public boolean equals(java.lang.Object type)

Description copied from class: MathType

ScalarTypes are equal if they have the same name; TupleTypes are equal if their components are equal; FunctionTypes are equal if their domains and ranges are equal

Specified by:

equals in class MathType

hashCode

public int hashCode()

Returns the hash code of this instance. If equals(Object type), then hashCode() == type.hashCode().

Overrides:

hashCode in class java.lang.Object

Returns:

The hash code of this instance.

equalsExceptName

public boolean equalsExceptName(MathType type)

Description copied from class: MathType

this is useful for determining compatibility of Data objects for binary mathematical operations; any RealTypes are equal; any TextTypes are equal; TupleTypes are equal if their components are equal; FunctionTypes are equal if their domains and ranges are equal

Specified by:

equalsExceptName in class MathType
