Method Details

stringify

public String stringify(boolean includePositionalInfo)

Specified by:

stringify in class AstNode

Parameters:

includePositionalInfo - position information is returned as a part of the result if set to true.

Returns:

a string representation of the AST. Useful for debugging/testing.

toString

public String toString()

Overrides:

toString in class Object

getAppNodes

public List<AppNode> getAppNodes()

getSourceDestinationNode

public SourceDestinationNode getSourceDestinationNode()

getSinkDestinationNode

public SinkDestinationNode getSinkDestinationNode()

getStreamName
