getSourceCode

public List<String> getSourceCode()

Specified by:

getSourceCode in interface Statement

Overrides:

getSourceCode in class ExpressionImpl

toString

public String toString()

Overrides:

toString in class ExpressionImpl

getNodeType

public int getNodeType()

Description copied from interface: ExpressionInterface

QDL is not strongly typed but Java is, so each node type should have a unique integer and conditionals should use that, not the instanceof operator. This allows for efficient programming with switch statements rather than a bevy of conditionals (potentially each of which gets done even if the correct case has been handled).

Specified by:

getNodeType in interface ExpressionInterface

Overrides:

getNodeType in class ConstantNode

Returns:
