Constructor Detail

LiteralArrayNode

public LiteralArrayNode(ClassNode baseTypeNode,
                        int numDimensions,
                        List<?> initialValue)

Constructor.

Parameters:

baseTypeNode - array base type class node

numDimensions - number of array dimensions

initialValue - array initial value; each element in the list is either a List (all but the last dimension) or a Node (last dimension)

Method Detail

evaluate

public Value evaluate(ParseSession session)

Description copied from interface: Node

Evaluate this node. There will be a transaction open.

Parameters:

session - parse session

Returns:

result of node evaluation

parseArrayLiteral

public static List<?> parseArrayLiteral(ParseSession session,
                                        ParseContext ctx,
                                        boolean complete,
                                        int dims)

Parse an array literal initial value expression.

Parameters:

session - parse session

ctx - input to parse

complete - false if parse is "for real", true if only for tab completion calculation

dims - number of array dimensions

Returns:

list of array elements, possibly nested

Throws:

IllegalArgumentException - if dims is less than one

getBaseType

protected Class<?> getBaseType(ParseSession session)

Resolve the array base type.

Parameters:

session - parse session

Returns:

resolved array base type

Throws:

EvalException - if base type is void

EvalException - if base type cannot be resolved

getType

public Class<?> getType(ParseSession session)

Description copied from interface: Node

Get the type of this node's value.

If the type is unknown, Object.class should be returned.

Specified by:

getType in interface Node

Parameters:

session - parse session

Returns:

the expected type of the node
