Constructor Detail

PsReal

public PsReal(BigDecimal value)

Constructor for a BigDecimal value.

Parameters:

value - The value to encapsulate.

Method Detail

clone

public PsReal clone()

Specified by:

clone in class PsNumber

create

public static PsReal create(PsInterpreter4a interpreter,
                            byte[] input)

Static method to attempt to create a PSReal instance, if the input qualifies.

Parameters:

interpreter - The parent interpreter.

input - The byte array containing the content to be converted to a PSReal instance.

Returns:

A PsReal instance, if the input qualifies, otherwise, null.

duplicate

public PsReal duplicate()

Description copied from interface: PsObject

This is a shallow copy. Specifically, composite objects should generally return themselves. Simple objects should return copies of themselves.

Returns:

A duplicate of this that conforms to what is expected by the "dup" operator.

isExecutable

public boolean isExecutable()

Description copied from interface: PsObject

Indicates whether this object is executable.

Returns:

True iff this object is executable.

getTypeName

public PsName getTypeName()

Description copied from interface: PsObject

Needed for the "type" operator.

Returns:

The type name as defined in PSRM2, Chapter 8, "type" operator.

toString

public String toString()

Overrides:

toString in class Object

isComposite

public boolean isComposite()

Description copied from interface: PsObject

The method should be overridden by composite objects.

Returns:

True iff this object is a composite PostScript object.
