buildCollationKeys

protected List buildCollationKeys(Collator collator)

Build a list of collation keys for comparing locale sensitive strings or build the appropriate objects for comparison for other standard data types.

Parameters:

collator - the Collator object to use to build String keys

swap

Returns:

Comparator for the appropriate column data type

getGetterMethodName

Return the name of the Bean getter method for the specified getter name

Parameters:

name - of the field to build getter method name for e.g. "value"

Returns:

the name of the Bean getter method for the field name e.g. "getValue"
