Constructor Detail

PDNameTreeNode

public PDNameTreeNode(Class valueClass)

Constructor.

Parameters:

valueClass - The PD Model type of object that is the value.

PDNameTreeNode

public PDNameTreeNode(COSDictionary dict,
              Class valueClass)

Constructor.

Parameters:

dict - The dictionary that holds the name information.

valueClass - The PD Model type of object that is the value.

Method Detail

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.

getCOSDictionary

public COSDictionary getCOSDictionary()

Convert this standard java object to a COS object.

Returns:

The cos object that matches this Java object.

getKids

public List getKids()

Return the children of this node. This list will contain PDNameTreeNode objects.

Returns:

The list of children or null if there are no children.

setKids

public void setKids(List kids)

Set the children of this named tree.

Parameters:

kids - The children of this named tree.

getValue

public Object getValue(String name)
                throws IOException

The name to retrieve.

Parameters:

name - The name in the tree.

Returns:

The value of the name in the tree.

Throws:

IOException - If an there is a problem creating the destinations.

getNames

public Map<String,Object> getNames()
                            throws IOException

This will return a map of names. The key will be a string, and the value will depend on where this class is being used.

Returns:

ordered map of cos objects

Throws:

IOException - If there is an error while creating the sub types.

convertCOSToPD

protected Object convertCOSToPD(COSBase base)
                         throws IOException

Method to convert the COS value in the name tree to the PD Model object. The default implementation will simply use reflection to create the correct object type. Subclasses can do whatever they want.

Parameters:

base - The COS object to convert.

Returns:

The converted PD Model object.

Throws:

IOException - If there is an error during creation.

createChildNode

protected PDNameTreeNode createChildNode(COSDictionary dic)

Create a child node object.

Parameters:

dic - The dictionary for the child node object to refer to.

Returns:

The new child node object.

setNames

public void setNames(Map<String,? extends COSObjectable> names)

Set the names of for this node. The keys should be java.lang.String and the values must be a COSObjectable. This method will set the appropriate upper and lower limits based on the keys in the map.

Parameters:

names - map of names to objects, or null

getUpperLimit

public String getUpperLimit()

Get the highest value for a key in the name map.

Returns:

The highest value for a key in the map.

getLowerLimit

public String getLowerLimit()

Get the lowest value for a key in the name map.

Returns:

The lowest value for a key in the map.
