Method Detail

hasElementClass

public boolean hasElementClass(Class<?>... types)

Description copied from interface: TypeCoercer

Returns whether the leaf nodes of this type coercer outputs value that is an instance of the given class or its subclasses. Does not match non-leaf nodes like Map or List.

Specified by:

hasElementClass in interface TypeCoercer<D extends com.google.common.collect.ImmutableCollection<U>,C extends com.google.common.collect.ImmutableCollection<T>>

traverse

public void traverse(CellNameResolver cellRoots,
                     C object,
                     TypeCoercer.Traversal traversal)

Description copied from interface: TypeCoercer

Traverse an object guided by this TypeCoercer.

#{link Traversal#traverse} function will be called once for the object. If the object is a collection or map, it will also recursively traverse all elements of the map.

Specified by:

traverse in interface TypeCoercer<D extends com.google.common.collect.ImmutableCollection<U>,C extends com.google.common.collect.ImmutableCollection<T>>

fillUnconfigured
