Method Details

interceptGetVariable

public TypedValue interceptGetVariable(VariableInstance variableInstance,
 TypedValue value)

Description copied from interface: VariableInterceptor

Intercepts a variable read operation.

Specified by:

interceptGetVariable in interface VariableInterceptor

Parameters:

variableInstance - the variable instance being read

value - the raw typed value

Returns:

the intercepted typed value (may be null if filtered)

interceptGetHistoricVariable

public TypedValue interceptGetHistoricVariable(HistoricVariableInstance historicVariableInstance,
 TypedValue value)

Description copied from interface: VariableInterceptor

Intercepts a historic variable read operation.

Specified by:

interceptGetHistoricVariable in interface VariableInterceptor

Parameters:

historicVariableInstance - the historic variable instance being read

value - the raw typed value

Returns:

the intercepted typed value (may be null if filtered)

interceptCreateVariable

public CoreVariableInstance interceptCreateVariable(CoreVariableInstance variableInstance)

Description copied from interface: VariableInterceptor

Intercepts a variable create operation.

Specified by:

interceptCreateVariable in interface VariableInterceptor

Parameters:

variableInstance - the variable instance being created

Returns:

the variable instance to persist (may be the same instance, but must not be null)

interceptUpdateVariable

public TypedValue interceptUpdateVariable(CoreVariableInstance variableInstance,
 TypedValue newValue)

Description copied from interface: VariableInterceptor

Intercepts a variable update operation.

Specified by:

interceptUpdateVariable in interface VariableInterceptor

Parameters:

variableInstance - the variable instance being updated

newValue - the new typed value being set

Returns:

the value to persist (may be the same value, but must not be null)
