Method Detail

queryNameFromMethod

public String queryNameFromMethod(Class findTargetType,
                                  Method finderMethod)

Gets the query to execute based on the method name called.

This method handles query mapping based on the following rules:

1. "find", "list", and "iterate" prefixes are stripped
2. "count" prefix is replaced with "Count"
3. "InRange" suffix is stripped
4. The resulting method name is prepended with the simple name of the target type and a period

For example:

If findTargetType is User and finderMethod is "findAllInRange", the resulting query method would be User.All.

Specified by:

queryNameFromMethod in interface FinderNamingStrategy

Parameters:

findTargetType - class instance to find

finderMethod - finder method

Returns:

query name
