public class XmlExpression
extends XmlFragment

AST node for an embedded JavaScript expression within an E4X XML literal. Node type, like XmlLiteral, is Token.XML. The node length includes the curly braces.

Method Detail

getExpression

public AstNode getExpression()

Returns the expression embedded in {}

setExpression

public void setExpression(AstNode expression)

Sets the expression embedded in {}, and sets its parent to this node.

Throws:

java.lang.IllegalArgumentException - if expression is null

isXmlAttribute

public boolean isXmlAttribute()

Returns whether this is part of an xml attribute value

setIsXmlAttribute

public void setIsXmlAttribute(boolean isXmlAttribute)

Sets whether this is part of an xml attribute value

toSource

public java.lang.String toSource(int depth)

Description copied from class: AstNode

Emits 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 null children that are expected to be non-null when no errors are present. In this situation, the behavior of the toSource method is undefined: toSource implementations may assume that the AST node is error-free, since it is intended to be invoked only at runtime after a successful parse.

Specified by:

toSource in class AstNode

Parameters:

depth - the current recursion depth, typically beginning at 0 when called on the root node.

visit

public void visit(NodeVisitor v)

Visits this node, then the child expression.

Specified by:

visit in class AstNode

Parameters:

v - the object to call with this node and its children
