setParameter

X setParameter(String name,
             Object value)

Sets the given value as the value for the parameter with the given name.

Parameters:

name - The name of the parameter which should be set

value - The value of the parameter that should be set

The query builder for chaining calls

setParameter

X setParameter(String name,
             Calendar value,
             javax.persistence.TemporalType temporalType)

Sets the given Calendar value as the value for the parameter with the given name.

Parameters:

name - The name of the parameter which should be set

value - The value of the parameter that should be set

temporalType - The temporal type of the value

Returns:

The query builder for chaining calls

setParameter

X setParameter(String name,
             Date value,
             javax.persistence.TemporalType temporalType)

Sets the given Date value as the value for the parameter with the given name.

Parameters:

name - The name of the parameter which should be set

value - The value of the parameter that should be set

temporalType - The temporal type of the value

Returns:

The query builder for chaining calls

containsParameter

boolean containsParameter(String name)

Returns true if a parameter with the given name is registered, otherwise false.

Parameters:

name - The name of the parameter that should be checked

Returns:

True if the parameter is registered, otherwise false

isParameterSet

boolean isParameterSet(String name)

Returns true if a parameter with the given name is registered and a value has been set, otherwise false.

Parameters:

name - The name of the parameter that should be checked

getParameterValue

Object getParameterValue(String name)

Returns the set value for the parameter with the given name. If no value has been set, or the parameter does not exist, null is returned.

Parameters:

name - The name of the parameter for which the value should be returned
