Class TextFormatParseInfoTree

java.lang.Object

com.google.protobuf.TextFormatParseInfoTree

public class TextFormatParseInfoTree
extends Object

Data structure which is populated with the locations of each field value parsed from the text.

The locations of primary fields values are retrieved by getLocation or getLocations. The locations of sub message values are within nested TextFormatParseInfoTrees and are retrieve by getNestedTree or getNestedTrees.

The TextFormatParseInfoTree is created by a Builder.

Method Detail

getLocations

public List<TextFormatParseLocation> getLocations(Descriptors.FieldDescriptor fieldDescriptor)

Retrieve all the locations of a field.

Parameters:

fieldDescriptor - the Descriptors.FieldDescriptor of the desired field

Returns:

a list of the locations of values of the field. If there are not values or the field doesn't exist, an empty list is returned.

getLocation

public TextFormatParseLocation getLocation(Descriptors.FieldDescriptor fieldDescriptor,
                                           int index)

Get the location in the source of a field's value.

Returns the TextFormatParseLocation for index-th value of the field in the parsed text.

Parameters:

fieldDescriptor - the Descriptors.FieldDescriptor of the desired field

index - the index of the value.

Returns:

the TextFormatParseLocation of the value

Throws:

IllegalArgumentException - index is out of range

getNestedTrees

public List<TextFormatParseInfoTree> getNestedTrees(Descriptors.FieldDescriptor fieldDescriptor)

Retrieve a list of all the location information trees for a sub message field.

Parameters:

fieldDescriptor - the Descriptors.FieldDescriptor of the desired field

Returns:

A list of TextFormatParseInfoTree

getNestedTree

public TextFormatParseInfoTree getNestedTree(Descriptors.FieldDescriptor fieldDescriptor,
                                             int index)

Returns the parse info tree for the given field, which must be a message type.

Parameters:

fieldDescriptor - the Descriptors.FieldDescriptor of the desired sub message

index - the index of message value.

Returns:

the ParseInfoTree of the message value. null is returned if the field doesn't exist or the index is out of range.

Throws:

IllegalArgumentException - if index is out of range

builder

public static TextFormatParseInfoTree.Builder builder()

Create a builder for a ParseInfoTree.

Returns:

the builder
