Method Details

name

String name()

Returns the name of this parameter

Returns:

the name of this parameter

asParameter

default CqnParameter asParameter()

Description copied from interface: CqnValue

Casts this value to CqnParameter.

Specified by:

asParameter in interface CqnValue

Returns:

this value as a parameter

isParameter

default boolean isParameter()

Description copied from interface: CqnValue

Returns true if this is a CqnParameter.

Specified by:

isParameter in interface CqnValue

Returns:

true if this is a parameter, otherwise false

isPositional

default boolean isPositional()

Returns true if this is a positional parameter.

Returns:

true if this is a positional parameter, otherwise false

accept

default void accept(CqnVisitor visitor)

Description copied from interface: CqnToken

Traverses the expression tree represented by this token with a given visitor. The traversal order is depth-first. If this token has child nodes they are traversed first by dispatching the visitor to the children's accept methods. Afterwards this token is passed to the visitor's visit method specific for this token's type.

Specified by:

accept in interface CqnToken

Parameters:

visitor - the CqnVisitor
