Method Detail

forMethod

public static ValidationContext forMethod(com.google.protobuf.Message msg,
                                          com.google.protobuf.Descriptors.MethodDescriptor method)

public static ValidationContext forMessage(com.google.protobuf.Message msg)

forVersion

public static ValidationContext forVersion(com.google.protobuf.Message current,
                                           com.google.protobuf.Message prior)

push

public ValidationContext push(com.google.protobuf.Descriptors.FieldDescriptor fd)

Description copied from interface: ValidationContext

Push a member field of the current object onto the validation stack

Specified by:

push in interface ValidationContext

Parameters:

fd - The field that will be pushed onto the stack

Returns:

A validation context pointing at the field that has been pushed

pushOneOf

public ValidationContext pushOneOf(com.google.protobuf.Descriptors.OneofDescriptor oneOf)

Description copied from interface: ValidationContext

Push a "one-of" field of the current object onto the validation stack

Specified by:

pushOneOf in interface ValidationContext

Parameters:

oneOf - The one-of field that will be pushed onto the stack

Returns:

A validation context pointing at the field that has been pushed

pushRepeated

public ValidationContext pushRepeated(com.google.protobuf.Descriptors.FieldDescriptor fd)

Description copied from interface: ValidationContext

Push a repeated member field of the current object onto the validation stack This method pushes a list onto the validation stack, so the target becomes a Java List object. To push individual list items, use pushRepeatedItem() after calling this method.

Specified by:

pushRepeated in interface ValidationContext

Parameters:

fd - The field that will be pushed onto the stack

Returns:

A validation context pointing at the list that has been pushed

pushRepeatedItem

public ValidationContext pushRepeatedItem(int index)

Description copied from interface: ValidationContext

Push an individual list item onto the validation stack Requires that the current target is a repeated field.

Specified by:

pushRepeatedItem in interface ValidationContext

Parameters:

index - The index of the list item to push onto the stack (must be within bounds of the list)

Returns:

A validation context pointing at the list item that has been pushed

pushRepeatedItem

public ValidationContext pushRepeatedItem(int index,
                                          java.lang.Object priorObj)

Description copied from interface: ValidationContext

Push an individual list item onto the validation stack Requires that the current target is a repeated field. This overload allows a prior version of the object to be specified for version comparison. This is helpful for version validators, which need to match current / prior entries in a list.

Specified by:

pushRepeatedItem in interface ValidationContext

Parameters:

index - The index of the list item to push onto the stack (must be within bounds of the list)

priorObj - The prior object to be compared against this list item in version validators

Returns:

A validation context pointing at the list item that has been pushed

pushRepeatedItem

public ValidationContext pushRepeatedItem(java.lang.Object obj,
                                          java.lang.Object priorObj)

Description copied from interface: ValidationContext

Push an individual list item onto the validation stack Requires that the current target is a repeated field. This overload allows a prior version of the object to be specified for version comparison. This is helpful for version validators, which need to match current / prior entries in a list.

Specified by:

pushRepeatedItem in interface ValidationContext

Parameters:

obj - The current list item to push onto the stack (must be a member of the list)

priorObj - The prior object to be compared against this list item in version validators

Returns:

A validation context pointing at the list item that has been pushed

pushMap

public ValidationContext pushMap(com.google.protobuf.Descriptors.FieldDescriptor fd)

Description copied from interface: ValidationContext

Push a map member field of the current object onto the validation stack This method will work with applyMapKeys() and applyMapValues(). If you need to look up map items by key or want to call pushMapKey() / pushMapValue() explicitly, use the overload which takes getMapFunc as a parameter (protobuf for Java does not provide a generic way of looking up map keys).

Specified by:

pushMap in interface ValidationContext

Parameters:

fd - The field that will be pushed onto the stack

Returns:

A validation context pointing at the map that has been pushed (this is not a Map object)

pushMap

public <TMsg extends com.google.protobuf.Message> ValidationContext pushMap(com.google.protobuf.Descriptors.FieldDescriptor mapField,
                                                                            java.util.function.Function<TMsg,java.util.Map<?,?>> getMapFunc)

Description copied from interface: ValidationContext

Push a map member field of the current object onto the validation stack This method only pushes the map itself onto the stack, the validation target will be a Java Map object. To push individual keys or values, use pushMapKey() or pushMapValue() after calling this method. This method needs a method reference from the parent message class to return Java map object associated with this field (protobuf for Java does not yet provide a generic way of looking up map keys).

Specified by:

pushMap in interface ValidationContext

Parameters:

mapField - The field that will be pushed onto the stack

getMapFunc - Method reference, on the parent message to return the field as a Java map

Returns:

A validation context pointing at the map that has been pushed (this is a Map object)

pushMapKey

public ValidationContext pushMapKey(java.lang.Object key)

Description copied from interface: ValidationContext

Push an individual map key onto the validation stack Requires that the current target is a map field.

Specified by:

pushMapKey in interface ValidationContext

Parameters:

key - The map key to push onto the stack

Returns:

A validation context pointing at the map key that has been pushed

pushMapValue

public ValidationContext pushMapValue(java.lang.Object key)

Description copied from interface: ValidationContext

Push an individual map value onto the validation stack Requires that the current target is a map field.

Specified by:

pushMapValue in interface ValidationContext

Parameters:

key - The key of the map value to push onto the stack

Returns:

A validation context pointing at the map value that has been pushed

pop

public ValidationContext pop()

Description copied from interface: ValidationContext

Pop the current object from the validation stack

Specified by:

pop in interface ValidationContext

Returns:

A validation context pointing at the parent of the current object

error

public ValidationContext error(java.lang.String message)

Description copied from interface: ValidationContext

Record an error against the current location in the validation stack

Specified by:

error in interface ValidationContext

Parameters:

message - The error message to record

Returns:

A validation context which includes the recorded error

skip

public ValidationContext skip()

Description copied from interface: ValidationContext

Skip the current location in the validation stack Any future calls to apply() at this location or child locations will be ignored. Errors already recorded at this location or child locations are still included in the validation report.

Specified by:

skip in interface ValidationContext

Returns:

A validation context with the current object marked as skipped
