Method Detail

addToIndex

public void addToIndex(KeyStoreData data,
                       KeyStoreDataMap dataMap)
Links the KeyStoreData object passed in with a hash of the label from the data object passed in. The dataMap is used by the key store to find the appropriate records when doing searches based on this index.

Parameters:
data - The KeyStoreData object containing the label.
dataMap - The data map where the link is added.

getHash

public int getHash(Object target)
Returns a hash representing the target object passed in.

Parameters:
target - The object to generate the hash on. Must be a String.
Returns:
An integer representing the hash of the target object passed into this method.
Throws:
IllegalArgumentException - if the specified target parameter is not a String.

public boolean matches(KeyStoreData data,
                       Object target)
Determines if the target object ( a String containing a label ) matches the label contained within the data object.

Parameters:
data - The key store data to compare against the target.
target - A String containing the label to compare against the data.
Returns:
true if the key store data object contains the same label as the target and false otherwise
