set of parameter objects

isBound

public boolean isBound(Parameter<?> parameter)

Description copied from interface: Query

Returns a boolean indicating whether a value has been bound to the parameter.

Specified by:

isBound in interface Query

Parameters:

parameter - parameter object

Returns:

boolean indicating whether parameter has been bound

getParameterValue

public Object getParameterValue(String name)

Description copied from interface: Query

Returns the input value bound to the named parameter.

Specified by:

getParameterValue in interface Query

Parameters:

name - parameter name

Returns:

parameter value

getParameterValue

public Object getParameterValue(int position)

Description copied from interface: Query

Returns the input value bound to the positional parameter.

Specified by:

getParameterValue in interface Query

Parameters:

position - position

Returns:

parameter value

getParameterValue

public <T> T getParameterValue(Parameter<T> parameter)

Description copied from interface: Query

Returns the input value bound to the parameter.

Specified by:

getParameterValue in interface Query

Parameters:

parameter - parameter object

Returns:

parameter value

setParameter

public Query setParameter(int position,
 Object value)

Description copied from interface: Query

Binds an argument value to a positional parameter.

This version exploits the type of the parameter value and maps it to the corresponding XSD datatype (if it exists).

Specified by:

setParameter in interface Query

Parameters:

position - position

value - parameter value

Returns:

this query instance

See Also:

• Query.setUntypedParameter(int, Object)

setParameter

public Query setParameter(int position,
 String value,
 String language)

Description copied from interface: Query

Binds a String argument value to a positional parameter.

Specified by:

setParameter in interface Query

Parameters:

position - position

value - parameter value

language - language tag for the parameter value

Returns:

this query instance

setParameter

public Query setParameter(String name,
 Object value)

Description copied from interface: Query

Binds an argument value to a named parameter.

This version exploits the type of the parameter value and maps it to the corresponding XSD datatype (if it exists).

Specified by:

setParameter in interface Query

Parameters:

name - parameter name

value - parameter value

Returns:

this query instance

See Also:

• Query.setUntypedParameter(String, Object)

setParameter

public Query setParameter(String name,
 String value,
 String language)

Description copied from interface: Query

Binds a String argument value to a named parameter.

Specified by:

setUntypedParameter

public Query setUntypedParameter(int position,
 Object value)

Description copied from interface: Query

value - parameter value

Returns:

this query instance

setUntypedParameter

public Query setUntypedParameter(String name,
 Object value)
