Method Details

isVector

default boolean isVector()

Description copied from interface: CqnLiteral

Returns true if this is a CqnVector.

Specified by:

isVector in interface CqnLiteral<CdsVector>

Returns:

true if this is a vector, otherwise false

asVector

default CqnVector asVector()

Description copied from interface: CqnLiteral

Casts this literal to CqnVector.

Specified by:

asVector in interface CqnLiteral<CdsVector>

Returns:

this literal as a vector

type

default Optional<String> type()

Description copied from interface: CqnValue

Returns the optional CDS type of this value.

Specified by:

type in interface CqnValue

Returns:

the optional CDS type

isConstant

default boolean isConstant()

Description copied from interface: CqnLiteral

Specifies if this CqnLiteral should be handled as a constant value during query execution.

Specified by:

isConstant in interface CqnLiteral<CdsVector>

Returns:

true if the literal can be handled as a constant value

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
