Class XMPIteratorImpl

java.lang.Object

com.adobe.internal.xmp.impl.XMPIteratorImpl

All Implemented Interfaces:

XMPIterator, Iterator

public class XMPIteratorImpl
extends Object
implements XMPIterator

The XMPIterator implementation. Iterates the XMP Tree according to a set of options. During the iteration the XMPMeta-object must not be changed. Calls to skipSubtree() / skipSiblings() will affect the iteration. FfF: Introduce a lock mechanism to prohibit changes in the XMPTree during the iteration; FfF: will throw a ConcurrentModificationException.

XMPIteratorImpl

public XMPIteratorImpl(XMPMetaImpl xmp,
                       String schemaNS,
                       String propPath,
                       IteratorOptions options)
                throws XMPException

Constructor with optionsl initial values. If propName is provided, schemaNS has also be provided.

Parameters:

xmp - the iterated metadata object.

schemaNS - the iteration is reduced to this schema (optional)

propPath - the iteration is redurce to this property within the schemaNS

options - advanced iteration options, see IteratorOptions

Throws:

XMPException - If the node defined by the paramters is not existing.
