All Implemented Interfaces:

Serializable, Iterator<AssetMeaning>

public abstract class AssetMeanings
extends AssetPropertyIteratorBase
implements Iterator<AssetMeaning>

Meanings supports an iterator over a list of glossary definitions. Callers can use it to step through the list just once. If they want to parse the list again, they could use the copy/clone constructor to create a new iterator.

Constructor Detail

AssetMeanings

public AssetMeanings(AssetDescriptor parentAsset,
                     int totalElementCount,
                     int maxCacheSize)

Typical Constructor creates an iterator with the supplied list of elements.

Parameters:

parentAsset - descriptor of parent asset

totalElementCount - the total number of elements to process. A negative value is converted to 0.

maxCacheSize - maximum number of elements that should be retrieved from the property server and cached in the element list at any one time. If a number less than one is supplied, 1 is used.

AssetMeanings

public AssetMeanings(AssetDescriptor parentAsset,
                     AssetMeanings template)

Copy/clone constructor. Used to reset iterator element pointer to 0;

Parameters:

parentAsset - descriptor of parent asset

template - type-specific iterator to copy; null to create an empty iterator

Method Detail

cloneElement

protected AssetPropertyBase cloneElement(AssetDescriptor parentAsset,
                                         AssetPropertyBase template)

Provides a concrete implementation of cloneElement for the specific iterator type.

Specified by:

cloneElement in class AssetPropertyIteratorBase

Parameters:

parentAsset - descriptor of parent asset

template - object to clone

Returns:

new cloned object.

cloneIterator

protected abstract AssetMeanings cloneIterator(AssetDescriptor parentAsset)

Clones this iterator.

Parameters:

parentAsset - descriptor of parent asset

Returns:

new cloned object.

hasNext

public boolean hasNext()

The iterator can only be used once to step through the elements. This method returns a boolean to indicate if it has got to the end of the list yet.

Specified by:

hasNext in interface Iterator<AssetMeaning>

Returns:

boolean indicating whether there are more elements.

next

public AssetMeaning next()

Return the next element in the iteration.

Specified by:

next in interface Iterator<AssetMeaning>

Returns:

Meaning next element object that has been cloned.

remove

public void remove()

Remove the current element in the iterator. (Null implementation since this iterator works off of cached elements from the property (metadata) server.)

Specified by:

remove in interface Iterator<AssetMeaning>

toString

public String toString()

Standard toString method.

Overrides:

toString in class AssetPropertyElementBase

Returns:

print out of variables in a JSON-style
