Constructor Detail

ValueType

public ValueType(int type)

Constructor to create a new ValueType based on value type.

Parameters:

type - an integer to distinguish types.

Method Detail

valueOf

public static ValueType valueOf(java.lang.String type)

Get a ValueType based on a string representation.

Parameters:

type - the string form of the type.

Returns:

the type corresponding to string type.

isReal

public boolean isReal()

Convenience method to determine if this ValueType is of class Real.

Returns:

true if type class of this is ClassReal.

isLogAngle

public boolean isLogAngle()

Convenience method to determine if this ValueType is of class Log.

Returns:

true if type class of this is ClassLog.

isAngular

public boolean isAngular()

Convenience method to determine if this ValueType is of class Angle or Real Angle.

Returns:

true if type of this is either #Angle or #RealAngle.

isExp

public boolean isExp()

Convenience method to determine if this ValueType is of class Exp.

Returns:

true if type class of this is ClassExp.

hasSameClass

final boolean hasSameClass(ValueType other)

Method to determine of two ValueTypes are of same class.

Parameters:

other - the ValueType to compare.

Returns:

true if this and other belong to same class.

getTypeClass

final ValueType getTypeClass()

getCastingType

final ValueType getCastingType()

conversion

final int conversion(ValueType newType)

canCast

public final boolean canCast(ValueType to)

Method returns true if it is legal to cast a value of type from to type to Identities are considered uncastable Note that casting always changes the effective value, without changing the correponding value shown

Parameters:

to - the type to which a Value might be cast.

Returns:

true if a Typed object of type this can be cast to type to.

absBoundType

public final boolean absBoundType()

Method to determine if this type goes with absolute bounds in a TValue.

Returns:

true if the type is None, Angle, Log, RealAbs or RealAngle.

toString

public java.lang.String toString()

Description copied from class: BaseNumber

"ValueType: " followed by the identifier.

getIdentifier

public java.lang.String getIdentifier()

Method to get the specific identifier for an object.

Specified by:

getIdentifier in interface Auditable

Overrides:

getIdentifier in class Manifest

Returns:

String: the identifier.

audit

public java.lang.String audit(java.lang.String label)

Method to return a detailed string from an object for debugging purposes.

Specified by:

audit in interface Auditable

Overrides:

audit in class Manifest

Parameters:

label - String: the label to associate with the data

Returns:

the detailed string.
