Constructor Detail

PjArray

public PjArray()

Creates an empty array.

PjArray

public PjArray(java.util.Vector v)

Creates an array as a wrapper around a Vector.

Parameters:

v - the Vector to use for this array.

Method Detail

getVector

public java.util.Vector getVector()

Returns the Vector used to represent this array.

Returns:

the Vector used to represent this array.

writePdf

public long writePdf(java.io.OutputStream os)
              throws java.io.IOException

Writes this array to a stream in PDF format.

Specified by:

writePdf in class BaseObject

Parameters:

os - the stream to write to.

Returns:

the number of bytes written.

Throws:

java.io.IOException - if an I/O error occurs.

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Returns a deep copy of this object.

Specified by:

clone in class BaseObject

Returns:

a deep copy of this object.

Throws:

java.lang.CloneNotSupportedException - if the instance can not be cloned.

cloneVector

protected java.util.Vector cloneVector()
                                throws java.lang.CloneNotSupportedException

Throws:

java.lang.CloneNotSupportedException

renumber

public void renumber(java.util.Hashtable map)

Renumbers object references within this object. This method calls itself recursively to comprehensively renumber all objects contained within this object.

Overrides:

renumber in class PjObject

Parameters:

map - the table of object number mappings. Each object number is looked up by key in the hash table, and the associated value is assigned as the new object number. The map hash table should consist of PjNumber keys and PjReference values.
