Description

I need to use spring with Tika. Is it thread safe to use the following injected from bean context. I am injecting parseContext, handler and parser into my class TikaImpl.
================
<bean name="parseContext" class="org.apache.tika.parser.ParseContext"></bean>
<bean name="parser" class="org.apache.tika.parser.AutoDetectParser"></bean>
<bean name="handler" class="org.xml.sax.helpers.DefaultHandler"></bean>

<bean id="tikaService" class="com.intech.tika.TikaImpl">
<property name="parseContext" ref="parseContext"></property>
<property name="parser" ref="parser"></property>
<property name="handler" ref="handler"></property>
<property name="resourcesize"><value>10485760</value></property>
</bean>
===============
In my class I have 3 methods 1. To retrieve metadata 2. to retrieve content 3. to retrieve both.

So for 1. Retrieve metadata, I am using:
parser.parse(stream, handler,
metadata, parseContext)
2. To retrieve the content, i am using:
Tika tika = new Tika();
tika.setMaxStringLength(resourcesize);
String content = tika.parseToString(stream);
3. To retrieve both: I am using:
BodyContentHandler bodyContentHandler = new BodyContentHandler(resourcesize);
Metadata metadata = new Metadata();
parser.parse(TikaInputStream.get(stream), bodyContentHandler, metadata, parseContext);

Question is:
Is my approach thread safe? Introduced 3 methods, thinking that just getting metadata from the first method is faster than the 3rd method.

Need your suggestion badly. Thank you in advance.
