Method Detail

create

public static FloatingPointValue create(char[] fixedValue)

create

public static FloatingPointValue create(double value)

numberValue

public java.lang.Number numberValue()

Description copied from interface: IValue

Returns the value as a number, or null if it is not possible.

Specified by:

numberValue in interface IValue

numberOfSubValues

public int numberOfSubValues()

Description copied from interface: IValue

If this value consists of sub-values, returns the number of these sub-values. Otherwise returns 1.

Specified by:

numberOfSubValues in interface IValue

getSubValue

public ICPPEvaluation getSubValue(int index)

Description copied from interface: IValue

If this value consists of sub-values, returns the sub-value at the given index. Otherwise, returns this value (represented as an ICPPEvaluation) if the index 0 is passed. EvalFixed.INCOMPLETE is returned if the given index is out of bounds.

Specified by:

getSubValue in interface IValue

getAllSubValues

public ICPPEvaluation[] getAllSubValues()

Description copied from interface: IValue

If this value consists of sub-values, returns an array containing all of them. Otherwise, returns an array containing 1 element representing this value. Not all implementations implement this; some may return null.

Specified by:

getAllSubValues in interface IValue

getEvaluation

public ICPPEvaluation getEvaluation()

Description copied from interface: IValue

Returns the evaluation object if this value cannot be represented as a single numerical value, or null otherwise. This can happen if the value is dependent, or it's a composite value. If IValue.numberValue() returns null, IValue.getEvaluation() returns not null and vice versa.

Specified by:

getEvaluation in interface IValue

getSignature

public char[] getSignature()

Description copied from interface: IValue

Returns a signature uniquely identifying the value. Two values with identical signatures are guaranteed to be equal.

Specified by:

getSignature in interface IValue

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

setSubValue

public void setSubValue(int position,
                        ICPPEvaluation newValue)

Description copied from interface: IValue

If this value consists of sub-values, set the sub-value at the given position to the given new value. Otherwise, set this value to the given new value. Not all implementations implement this; for some, a call to this may have no effect.

Specified by:

setSubValue in interface IValue

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

clone

public IValue clone()

Description copied from interface: IValue

Make a deep copy of this value.

Specified by:

clone in interface IValue

Overrides:

clone in class java.lang.Object

marshal

public void marshal(ITypeMarshalBuffer buf)
             throws CoreException

Description copied from interface: IValue

Serialize this value to the given type marshal buffer.

Specified by:

marshal in interface IValue

Throws:

CoreException

unmarshal

public static IValue unmarshal(short firstBytes,
                               ITypeMarshalBuffer buf)
                        throws CoreException

Throws:

CoreException
