Class RangeSpecifier

Object
  RangeSpecifier

All Implemented Interfaces:

Serializable, Cloneable

public class RangeSpecifier
extends Object
implements Serializable, Cloneable

Argument type for DefaultProcessor operations for specifying the range, colors and units of a computation result. RangeSpecifier are used for tuning the Category object to be constructed. For example the "GradientMagnitude" operation will produces new GridCoverage2D with sample values ranging from 0 to some maximal value which may be very different from the source GridCoverage2D range. By default, most operations try to guess a raisonable range for output values. This default behavior can be overridden with an explicit RangeSpecifier argument.

All RangeSpecifier's properties are optional; it is up to processor's operation to replace null values by a default one.

Constructor Detail

RangeSpecifier

public RangeSpecifier()

Constructs a default RangeSpecifier with no value set.

RangeSpecifier

public RangeSpecifier(NumberRange<?> range)

Constructs a RangeSpecifier initialised to the spécified range.

Parameters:

range - The range

RangeSpecifier

public RangeSpecifier(MathTransform1D transform)

Constructs a RangeSpecifier initialised to the specified "sample to geophysics" transform.

Parameters:

transform - The sample to geophysics transform.

Method Detail

getRange

public NumberRange<?> getRange()

Returns the target range, or null if none.

Returns:

The range

setRange

public void setRange(NumberRange<?> range)

Set the target range to the specified values. Setting this property will clear the sample to geophysics transform, since those properties are mutually exclusive.

Parameters:

range - The target range.

getSampleToGeophysics

public MathTransform1D getSampleToGeophysics()

Returns the target "sample to geophysics" transform, or null if none.

Returns:

The current sample to geophysics transform.

setSampleToGeophysics

public void setSampleToGeophysics(MathTransform1D transform)

Set the target "sample to geophysics" transform to the specified value. Setting this property will clear the range property, since those properties are mutually exclusive.

Parameters:

transform - The new sample to geophysics transform.

getUnit

public Unit<?> getUnit()

Returns the target range units, or null if none.

Returns:

The current units.

setUnit

public void setUnit(Unit<?> unit)

Set the target range units to the specified value.

Parameters:

unit - The new units.

getColors

public Color[] getColors()

Returns the target colors, or null if none.

Returns:

The current colors.

setColors

public void setColors(Color[] colors)

Set the target colors to the specified value.

Parameters:

colors - The new colors.

clone

public RangeSpecifier clone()

Returns a clone of this object.

Overrides:

clone in class Object

Returns:

A clone of this object.

See Also:

Object.clone()

hashCode

public int hashCode()

Returns a hash code value for this range specifier.

Overrides:

hashCode in class Object

equals

public boolean equals(Object object)

Compares this range specifier with the specified object for equality.

Overrides:

equals in class Object

Parameters:

object - The object to compare with.

Returns:

true if the given object is equals to this range specifier.

toString

public String toString()

Returns a string representation of this range specifier.

Overrides:

toString in class Object
