Constructor Detail

ParameterHashVisitor

public ParameterHashVisitor()

Public constructor.

ParameterHashVisitor

public ParameterHashVisitor(boolean legacyWholeSystemSearchParamsEnabled)

Public constructor.

Parameters:

legacyWholeSystemSearchParamsEnabled - if true, then update digest to ensure hash changes from when it is false; this can be removed when the legacyWholeSystemSearchParamsEnabled config setting is removed.
