Constructor Details

ArrayConstructorExpression

public ArrayConstructorExpression(Expression expression,
 ExceptionMetadata metadata)

Curly array constructor: array { expr }. Each item produced by the expression becomes a singleton member.

ArrayConstructorExpression

public ArrayConstructorExpression(ExceptionMetadata metadata)

Empty array constructor (curly or square with no members).

ArrayConstructorExpression

public ArrayConstructorExpression(List<Expression> memberExpressions,
 boolean isFixedSlotsArrayConstructor,
 ExceptionMetadata metadata)

Square array constructor: [ E1, E2, ... ]. Each expression becomes a separate member whose result (possibly a sequence) is preserved.

Method Details

getExpression

public Expression getExpression()

getMemberExpressions

public List<Expression> getMemberExpressions()

isFixedSlotsArrayConstructor

public boolean isFixedSlotsArrayConstructor()

getChildren

public List<Node> getChildren()

Description copied from class: Node

Returns all children nodes as a list. The list is new and can be modified at will by the caller.

Specified by:

getChildren in class Node

Returns:

the children nodes as a list.

serializeToJSONiq

public void serializeToJSONiq(StringBuffer sb,
 int indent)

Specified by:

serializeToJSONiq in class Node

accept

public <T> T accept(AbstractNodeVisitor<T> visitor,
 T argument)

Description copied from class: Node

Accept method for the visitor pattern.

Specified by:

accept in class Node

Type Parameters:

T - the type of the objects returned by the visitor.

Parameters:

visitor - the visitor.

argument - the input from the visitor.

Returns:

the object returned by this visitor
