accept

public Object accept(ICOSObjectVisitor visitor)
              throws COSVisitorException

Description copied from class: COSDocumentElement

Accept a visitor object. The receiver selects the correct implementation in the visitor by "double dispatching".

Specified by:

accept in class COSDocumentElement

Parameters:

visitor - The object visiting the receiver.

Returns:

Object An object depending on the visitor semantics.

Throws:

COSVisitorException - An exception depending on the visitor semantics.

asFixed

public COSFixed asFixed()

Overrides:

asFixed in class COSObject

Returns:

a COSFixed or null

equals

public boolean equals(Object o)

Overrides:

equals in class Object

floatValue

public float floatValue()

Description copied from class: COSNumber

Answer the value of the receiver as a float

Specified by:

floatValue in class COSNumber

Returns:

Answer the value of the receiver as a float

getPrecision

public int getPrecision()

The precision (digits after period) for this.

Returns:

The precision (digits after period) for this.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

intValue

public int intValue()

Description copied from class: COSNumber

Answer the value of the receiver as a int

Specified by:

intValue in class COSNumber

Returns:

Answer the value of the receiver as a int

restoreState

public void restoreState(Object object)

Specified by:

restoreState in interface de.intarsys.tools.component.ISaveStateSupport
