public class XmlElemRef extends XmlRef
AST node for an E4X XML[expr]member-ref expression. The node type isToken.REF_MEMBER.Syntax:
@opt ns:: opt [ expr ]
Examples includens::[expr],@ns::[expr],@[expr],*::[expr]and@*::[expr].Note that the form
[expr](i.e. no namespace or attribute-qualifier) is not a legalXmlElemRefexpression, since it's already used for standard JavaScriptElementGetarray-indexing. Hence, anXmlElemRefnode always has either the attribute-qualifier, a non-nullnamespace node, or both.The node starts at the
@token, if present. Otherwise it starts at the namespace name. The node bounds extend through the closing right-bracket, or if it is missing due to a syntax error, through the end of the index expression.

Method Detail
-
getExpression
public AstNode getExpression()
Returns index expression: the 'expr' in@[expr]or@*::[expr].
-
setExpression
public void setExpression(AstNode expr)
Sets index expression, and sets its parent to this node.- Throws:
java.lang.IllegalArgumentException- ifexprisnull
-
getLb
public int getLb()
Returns left bracket position, or -1 if missing.
-
setLb
public void setLb(int lb)
Sets left bracket position, or -1 if missing.
-
getRb
public int getRb()
Returns left bracket position, or -1 if missing.
-
setRb
public void setRb(int rb)
Sets right bracket position, -1 if missing.
-
setBrackets
public void setBrackets(int lb, int rb)Sets both bracket positions.
-
toSource
public java.lang.String toSource(int depth)
Description copied from class:AstNodeEmits source code for this node. Callee is responsible for calling this function recursively on children, incrementing indent as appropriate.Note: if the parser was in error-recovery mode, some AST nodes may have
nullchildren that are expected to be non-nullwhen no errors are present. In this situation, the behavior of thetoSourcemethod is undefined:toSourceimplementations may assume that the AST node is error-free, since it is intended to be invoked only at runtime after a successful parse.
-
visit
public void visit(NodeVisitor v)
Visits this node, then the namespace if provided, then the index expression.
