Constructor Detail

InterpolateObjectAction

public InterpolateObjectAction(java.lang.Object target,
                               BasicInterpolator interpolator,
                               RecursionInterceptor recursionInterceptor,
                               java.util.Set blacklistedFieldNames,

                               java.util.List<ObjectInterpolationWarning> warningCollector)

Setup an object graph traversal for the given target starting point. This will initialize a queue of objects to traverse and interpolate by adding the target object.

Method Detail

run

public java.lang.Object run()

As long as the traversal queue is non-empty, traverse the next object in the queue. If an interpolation error occurs, return it immediately.

Specified by:

run in interface java.security.PrivilegedAction

traverseObjectWithParents

private void traverseObjectWithParents(java.lang.Class cls,
                                       FieldBasedObjectInterpolator.InterpolationTarget target)
                                throws InterpolationException

Traverse the given object, interpolating any String fields and adding non-primitive field values to the interpolation queue for later processing.

Throws:

InterpolationException

interpolateObject

private void interpolateObject(java.lang.Object obj,
                               java.lang.String basePath,
                               java.lang.reflect.Field field)
                        throws java.lang.IllegalAccessException,
                               InterpolationException

Throws:

java.lang.IllegalAccessException

InterpolationException

interpolateMap

private void interpolateMap(java.lang.Object obj,
                            java.lang.String basePath,
                            java.lang.reflect.Field field)
                     throws java.lang.IllegalAccessException,
                            InterpolationException

Throws:

java.lang.IllegalAccessException

InterpolationException

interpolateCollection

private boolean interpolateCollection(java.lang.Object obj,
                                      java.lang.String basePath,
                                      java.lang.reflect.Field field)
                               throws java.lang.IllegalAccessException,
                                      InterpolationException

Throws:

java.lang.IllegalAccessException

InterpolationException

interpolateString

private void interpolateString(java.lang.Object obj,
                               java.lang.reflect.Field field)
                        throws java.lang.IllegalAccessException,
                               InterpolationException

Throws:

java.lang.IllegalAccessException

InterpolationException

isQualifiedForInterpolation

private boolean isQualifiedForInterpolation(java.lang.Class cls)

Using the package-prefix blacklist, determine whether the given class is qualified for interpolation, or whether it should be ignored.

isQualifiedForInterpolation

private boolean isQualifiedForInterpolation(java.lang.reflect.Field field,
                                            java.lang.Class fieldType)

Using the field-name blacklist and the primitive-field cache, determine whether the given field in the given class is qualified for interpolation. Primitive fields and fields listed in the blacklist will be ignored. The primitive-field cache is used to improve the performance of the reflective operations in this method, since this method is a hotspot.

evaluateArray

private void evaluateArray(java.lang.Object target,
                           java.lang.String basePath)
                    throws InterpolationException

Traverse the elements of an array, and interpolate any qualified objects or add them to the traversal queue.

Throws:

InterpolationException
