Constructor Detail

GuardedBinding

public GuardedBinding(ObjectHandler oh,
                      java.lang.String name,
                      TemplateContext tc,
                      Code code)

Method Detail

get

public java.lang.Object get(java.util.List<java.lang.Object> scopes)

Retrieve the first value in the stacks of scopes that matches the give name. The method wrappers are cached and guarded against the type or number of scopes changing. Methods will be found using the object handler, called here with another lookup on a guard failure and finally coerced to a final value based on the ObjectHandler you provide.

Specified by:

get in interface Binding

Parameters:

scopes - An array of scopes to interrogate from right to left.

Returns:

The value of the field or method

createAndGet

private java.lang.Object createAndGet(java.util.List<java.lang.Object> scopes)

getWrapper

protected Wrapper getWrapper(java.lang.String name,
                             java.util.List<java.lang.Object> scopes)

logWarning

public static void logWarning(java.lang.String warning,
                              java.lang.String name,
                              java.util.List<java.lang.Object> scopes,
                              TemplateContext tc)
