Method Detail

getIndex

int getIndex()

Returns the unique index of the slot.

getDefaultValueCalc

Calc getDefaultValueCalc()

Returns a compiled expression to compute the default value of the parameter.

getParameter

Parameter getParameter()

Returns the parameter.

setParameterValue

void setParameterValue(Object value,
                       boolean assigned)

Sets the value of this parameter.

NOTE: This method will be removed when we store parameter values in the Result rather than in the Query.

Parameters:

value - New value

assigned - Whether isParameterSet() should return true; supply value false if this is an internal assignment, to remember the default value

getParameterValue

Object getParameterValue()

Returns the value of this parameter.

NOTE: This method will be removed when we store parameter values in the Result rather than in the Query.

isParameterSet

boolean isParameterSet()

Returns whether the parameter has been assigned a value. (That value may be null.)

Returns:

Whether parmaeter has been assigned a value.

setCachedDefaultValue

void setCachedDefaultValue(Object value)

getCachedDefaultValue

Object getCachedDefaultValue()

unsetParameterValue

void unsetParameterValue()

Unsets the parameter value.
