Interface ObjectHandler

All Known Implementing Classes:

BaseObjectHandler, ReflectionObjectHandler, SimpleObjectHandler, TypeCheckingHandler

public interface ObjectHandler

The ObjectHandler is responsible for creating wrappers to find values in scopes at runtime and to coerce those results to the appropriate Java types

Method Summary

Modifier and Type	Method and Description
Object	coerce(Object object) Coerce results to Java native iterables, functions, callables.
Binding	createBinding(String name, TemplateContext tc, Code code) Each call site has its own binding to allow for fine grained caching without a separate parallel hierarchy of objects.
Writer	falsey(Iteration iteration, Writer writer, Object object, List<Object> scopes) Call Iteration.next() either 0 (true) or 1 (fale) times.
Wrapper	find(String name, List<Object> scopes) Find a value named "name" in the array of scopes in reverse order.
Writer	iterate(Iteration iteration, Writer writer, Object object, List<Object> scopes) Iterate over an object by calling Iteration.next for each value.
static List<Object>	makeList(Object scope)
String	stringify(Object object) Turns an object into the string representation that should be displayed in templates.

Method Detail

find

Wrapper find(String name,
             List<Object> scopes)

Find a value named "name" in the array of scopes in reverse order.

Parameters:

name - the variable name

scopes - the ordered list of scopes

Returns:

a wrapper that can be used to extract a value

coerce

Object coerce(Object object)

Coerce results to Java native iterables, functions, callables.

Parameters:

object - transform an unknown type to a known type

Returns:

the new object

iterate

Writer iterate(Iteration iteration,
               Writer writer,
               Object object,
               List<Object> scopes)

Iterate over an object by calling Iteration.next for each value.

Parameters:

iteration - callback for the next iteration

writer - the writer to write to

object - the current object

scopes - the scopes present

Returns:

the current writer

falsey

Writer falsey(Iteration iteration,
              Writer writer,
              Object object,
              List<Object> scopes)

Call Iteration.next() either 0 (true) or 1 (fale) times.

Parameters:

iteration - callback for the next iteration

writer - the writer to write to

object - the current object

scopes - the scopes present

Returns:

the current writer

createBinding

Binding createBinding(String name,
                      TemplateContext tc,
                      Code code)

Each call site has its own binding to allow for fine grained caching without a separate parallel hierarchy of objects.

Parameters:

name - the name that we bound

tc - the textual context of the binding site

code - the code that was bound

Returns:

the binding

stringify

String stringify(Object object)

Turns an object into the string representation that should be displayed in templates.

Parameters:

object - the object to be displayed

Returns:

a string representation of the object.

makeList

static List<Object> makeList(Object scope)
