MapInjectionResolver

public MapInjectionResolver(CommandModel model,
                            ParameterMap parameters,
                            org.jvnet.hk2.component.MultiMap<String,File> optionNameToUploadedFileMap)

Method Detail

setContext

public void setContext(ExecutionContext context)

Set the context that is passed to the DynamicParamImpl.defaultValue method.

isOptional

public boolean isOptional(AnnotatedElement element,
                          Param annotation)

Description copied from class: InjectionResolver

Returns true if the resolution of this injection identified by the passed annotation instance is optional

Overrides:

isOptional in class InjectionResolver<Param>

Parameters:

element - is the annotated java element Method or Field

annotation - the injection metadata

Returns:

true if the getValue() can return null without generating a faulty injection operation

getValue

public <V> V getValue(Object component,
                      AnnotatedElement target,
                      Type genericType,
                      Class<V> type)
               throws org.glassfish.hk2.api.MultiException

Description copied from interface: InjectionResolverQuery

Returns the value to inject in the field or method of component annotated with the annotated annotation.

Parameters:

component - injection target instance

target - is the annotated java element Method or Field

genericType - the generic type of the expected return

type - type of the expected return

Returns:

the resource to be injected

Throws:

org.glassfish.hk2.api.MultiException - if the resource cannot be located.

getUploadedFileParamValue

public static String getUploadedFileParamValue(String fieldName,
                                               Class fieldType,
                                               org.jvnet.hk2.component.MultiMap<String,File> optionNameToFileMap)

Returns the path to the uploaded file if the specified field is of type File and if the field name is the same as one of the option names that was associated with an uploaded File in the incoming command request.

Parameters:

fieldName - name of the field being injected

fieldType - type of the field being injected

optionNameToFileMap - map of field names to uploaded Files

Returns:

absolute path of the uploaded file for the field; null if no file uploaded for this field

getUploadedFileParamValues

public static List<String> getUploadedFileParamValues(String fieldName,
                                                      Class fieldType,
                                                      org.jvnet.hk2.component.MultiMap<String,File> optionNameToFileMap)

Returns the paths to the uploaded files if the specified field is of type File[] and if the field name is the same as one of the option names that was associated with an uploaded File in the incoming command request.

Parameters:

fieldName - name of the field being injected

fieldType - type of the field being injected

optionNameToFileMap - map of field names to uploaded Files

Returns:

List of absolute paths of the uploaded files for the field; null if no file uploaded for this field
