This class provides the same functionalities than Parameter , except that: Values are always floating point numbers of type double . Units are the same than the . When those conditions are meet, ParameterRealValue is slightly more efficient than ParameterValue since it avoid the creation of Double objects. since:    2.1 version:    $Id: FloatParameter.java 20874 2006-08-07 10:00:01Z jgarnett $ author:    Martin Desruisseaux See Also:   DefaultParameterDescriptor See Also:   ParameterGroup Constructor Summary public   FloatParameter(ParameterDescriptor descriptor)      Constructs a parameter from the specified descriptor. public   FloatParameter(ParameterDescriptor descriptor, double value)      Constructs a parameter from the specified descriptor and value.

Constructor Detail FloatParameter public FloatParameter(ParameterDescriptor descriptor)(Code) Constructs a parameter from the specified descriptor. The descriptor must be .class. Parameters:   descriptor - The abstract definition of this parameter. throws:   IllegalArgumentException - if the value class is not Double.class . FloatParameter public FloatParameter(ParameterDescriptor descriptor, double value)(Code) Constructs a parameter from the specified descriptor and value. This convenience constructor is equivalents to the one-argument constructor followed by a call to FloatParameter.setValue(double) . Parameters:   descriptor - The abstract definition of this parameter. Parameters:   value - The parameter value. throws:   IllegalArgumentException - if the value class is not Double.class . Method Detail booleanValue public boolean booleanValue()(Code) Returns true if the value is different from 0, false otherwise. The boolean value represented by this parameter. doubleValue public double doubleValue(Unit unit) throws IllegalArgumentException(Code) Returns the numeric value of the coordinate operation parameter in the specified unit of measure. This convenience method apply unit conversion on the fly as needed. Parameters:   unit - The unit of measure for the value to be returned. The numeric value represented by this parameter after conversion to type double and conversion to unit . throws:   IllegalArgumentException - if the specified unit is invalid for this parameter. doubleValue public double doubleValue()(Code) Returns the numeric value of the coordinate operation parameter with its associated . The numeric value represented by this parameter after conversion to type double . doubleValueList public double[] doubleValueList(Unit unit) throws IllegalArgumentException(Code) Wraps the value in an array of length 1. Parameters:   unit - The unit of measure for the value to be returned. The sequence of values represented by this parameter after conversion to type double and conversion to unit . throws:   IllegalArgumentException - if the specified unit is invalid for this parameter. doubleValueList public double[] doubleValueList()(Code) Wraps the value in an array of length 1. The sequence of values represented by this parameter. equals public boolean equals(Object object)(Code) Compares the specified object with this parameter for equality. Parameters:   object - The object to compare to this . true if both objects are equal. getUnit public Unit getUnit()(Code) Returns the unit of measure of the . The default implementation always delegates to ParameterDescriptor.getUnit . The unit of measure, or null if none. getValue public Object getValue()(Code) Returns the parameter value as { Double , The parameter value as an object. hashCode public int hashCode()(Code) Returns a hash value for this parameter. The hash code value. This value doesn't need to be the samein past or future versions of this class. intValue public int intValue()(Code) Returns the numeric value rounded to the nearest integer. The numeric value represented by this parameter after conversion to type int . intValueList public int[] intValueList()(Code) Wraps the value in an array of length 1. The sequence of values represented by this parameter. setValue public void setValue(double value, Unit unit) throws InvalidParameterValueException(Code) Set the parameter value as a floating point and its associated unit. Parameters:   value - The parameter value. Parameters:   unit - The unit for the specified value. throws:   InvalidParameterValueException - if the value is illegal for some reason(for example a value out of range). setValue public void setValue(double value) throws InvalidParameterValueException(Code) Set the parameter value as a floating point. Parameters:   value - The parameter value. throws:   InvalidParameterValueException - if the value is illegal for some reason(for example a value out of range). setValue public void setValue(int value) throws InvalidParameterValueException(Code) Set the parameter value as an integer. Parameters:   value - The parameter value. throws:   InvalidParameterValueException - if the value is illegal for some reason(for example a value out of range). setValue public void setValue(boolean value) throws InvalidParameterValueException(Code) Set the parameter value as a boolean. Parameters:   value - The parameter value. throws:   InvalidParameterValueException - if the boolean type is inappropriate for this parameter. setValue public void setValue(Object value) throws InvalidParameterValueException(Code) Set the parameter value as a Double object. Parameters:   value - The parameter value. throws:   InvalidParameterValueException - if the type of value is inappropriatefor this parameter, or if the value is illegal for some other reason (for examplethe value is numeric and out of range). setValue public void setValue(double[] values, Unit unit) throws InvalidParameterValueException(Code) Always throws an exception, since this parameter is not an array. stringValue public String stringValue()(Code) Returns the string representation of the value. The string value represented by this parameter. valueFile public URI valueFile() throws InvalidParameterTypeException(Code) Always throws an exception, since this parameter is not an URI. Never return. throws:   InvalidParameterTypeException - The value is not a reference to a file or an URI.
