Class PDTextStream

java.lang.Object

com.tom_roush.pdfbox.pdmodel.common.PDTextStream

All Implemented Interfaces:

COSObjectable

public class PDTextStream
extends Object
implements COSObjectable

A PDTextStream class is used when the PDF specification supports either a string or a stream for the value of an object. This is usually when a value could be large or small, for example a JavaScript method. This class will help abstract that and give a single unified interface to those types of fields.

Constructor Detail

PDTextStream

public PDTextStream(COSString str)

Constructor.

Parameters:

str - The string parameter.

PDTextStream

public PDTextStream(String str)

Constructor.

Parameters:

str - The string parameter.

PDTextStream

public PDTextStream(COSStream str)

Constructor.

Parameters:

str - The stream parameter.

Method Detail

createTextStream

public static PDTextStream createTextStream(COSBase base)

This will create the text stream object. base must either be a string or a stream.

Parameters:

base - The COS text stream object.

Returns:

A PDTextStream that wraps the base object.

getCOSObject

public COSBase getCOSObject()

Convert this standard java object to a COS object.

Specified by:

getCOSObject in interface COSObjectable

Returns:

The cos object that matches this Java object.

getAsString

public String getAsString()
                   throws IOException

This will get this value as a string. If this is a stream then it will load the entire stream into memory, so you should only do this when the stream is a manageable size.

Returns:

This value as a string.

Throws:

IOException - If an IO error occurs while accessing the stream.

getAsStream

public InputStream getAsStream()
                        throws IOException

This is the preferred way of getting data with this class as it uses a stream object.

Returns:

The stream object.

Throws:

IOException - If an IO error occurs while accessing the stream.
