Method Detail

getTarget

public AstNode getTarget()

Returns the object on which the property is being fetched. Should never be null.

setTarget

public void setTarget(AstNode target)

Sets target object, and sets its parent to this node.

Parameters:

target - expression evaluating to the object upon which to do the property lookup

Throws:

java.lang.IllegalArgumentException - if target is null

getProperty

public Name getProperty()

Returns the property being accessed.

setProperty

public void setProperty(Name property)

Sets the property being accessed, and sets its parent to this node.

Throws:

java.lang.IllegalArgumentException - if property is null

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.

Overrides:

toSource in class InfixExpression

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, the target expression, and the property name.

Overrides:

visit in class InfixExpression

Parameters:

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