public PDPageNode()
Creates a new instance of PDPage.
-
PDPageNode
public PDPageNode(COSDictionary pages)
Creates a new instance of PDPage.- Parameters:
pages
- The dictionary pages.
-

Method Detail
-
updateCount
public long updateCount()
This will update the count attribute of the page node. This only needs to be called if you add or remove pages. The PDDocument will call this for you when you use the PDDocumnet persistence methods. So, basically most clients will never need to call this.- Returns:
- The update count for this node.
-
getCount
public long getCount()
This will get the count of descendent page objects.- Returns:
- The total number of descendent page objects.
-
getDictionary
public COSDictionary getDictionary()
This will get the underlying dictionary that this class acts on.- Returns:
- The underlying dictionary for this class.
-
getParent
public PDPageNode getParent()
This is the parent page node.- Returns:
- The parent to this page.
-
setParent
public void setParent(PDPageNode parent)
This will set the parent of this page.- Parameters:
parent
- The parent to this page node.
-
getCOSObject
public COSBase getCOSObject()
Convert this standard java object to a COS object.- Specified by:
getCOSObject
in interfaceCOSObjectable
- Returns:
- The cos object that matches this Java object.
-
getKids
public java.util.List getKids()
This will return all kids of this node, either PDPageNode or PDPage.- Returns:
- All direct descendents of this node.
-
getAllKids
public void getAllKids(java.util.List result)
This will return all kids of this node as PDPage.- Parameters:
result
- All direct and indirect descendents of this node are added to this list.
-
getResources
public PDResources getResources()
This will get the resources at this page node and not look up the hierarchy. This attribute is inheritable, and findResources() should probably used. This will return null if no resources are available at this level.- Returns:
- The resources at this level in the hierarchy.
-
findResources
public PDResources findResources()
This will find the resources for this page by looking up the hierarchy until it finds them.- Returns:
- The resources at this level in the hierarchy.
-
setResources
public void setResources(PDResources resources)
This will set the resources for this page.- Parameters:
resources
- The new resources for this page.
-
getMediaBox
public PDRectangle getMediaBox()
This will get the MediaBox at this page and not look up the hierarchy. This attribute is inheritable, and findMediaBox() should probably used. This will return null if no MediaBox are available at this level.- Returns:
- The MediaBox at this level in the hierarchy.
-
findMediaBox
public PDRectangle findMediaBox()
This will find the MediaBox for this page by looking up the hierarchy until it finds them.- Returns:
- The MediaBox at this level in the hierarchy.
-
setMediaBox
public void setMediaBox(PDRectangle mediaBox)
This will set the mediaBox for this page.- Parameters:
mediaBox
