-
toString(
) → String -
A string representation of this object.

-
writeInto(
GenerationContext context) → void -
Writes this component into the
context
by writing to its GenerationContext.buffer or by introducing bound variables. When writing into the buffer, no whitespace around the this component should be introduced. When a component consists of multiple composed component, it's responsible for introducing whitespace between its child components.override -
writeStartPart(
GenerationContext ctx) → void - Subclasses must override this and write the part of the statement that comes before the where and limit expression..
