JsonFactory ("The Adobe AEM Quickstart and Web Application.")

java.lang.Object
- com.fasterxml.jackson.core.JsonFactory

All Implemented Interfaces:

Versioned, java.io.Serializable

Direct Known Subclasses:

MappingJsonFactory
```
public class JsonFactory
extends java.lang.Object
implements Versioned, java.io.Serializable
```
The main factory class of Jackson package, used to configure and construct reader (aka parser, JsonParser) and writer (aka generator, JsonGenerator) instances.
Factory instances are thread-safe and reusable after configuration (if any). Typically applications and services use only a single globally shared factory instance, unless they need differently configured factories. Factory reuse is important if efficiency matters; most recycling of expensive construct is done on per-factory basis.
Creation of a factory instance is a light-weight operation, and since there is no need for pluggable alternative implementations (as there is no "standard" JSON processor API to implement), the default constructor is used for constructing factory instances.

```
public JsonFactory()
```
    Default constructor used to create factory instances. Creation of a factory instance is a light-weight operation, but it is still a good idea to reuse limited number of factory instances (and quite often just a single instance): factories are used as context for storing some reused processing objects (such as symbol tables parsers use) and this reuse only works within context of a single factory instance.
  - JsonFactory
```
public JsonFactory(ObjectCodec oc)
```
- Method Detail
  - copy
```
public JsonFactory copy()
```
    Method for constructing a new JsonFactory that has the same settings as this instance, but is otherwise independent (i.e. nothing is actually shared, symbol tables are separate). Note that ObjectCodec reference is not copied but is set to null; caller typically needs to set it after calling this method. Reason for this is that the codec is used for callbacks, and assumption is that there is strict 1-to-1 mapping between codec, factory. Caller has to, then, explicitly set codec after making the copy.
    
    Since:
    
    2.1
  - requiresPropertyOrdering
```
public boolean requiresPropertyOrdering()
```
    Introspection method that higher-level functionality may call to see whether underlying data format requires a stable ordering of object properties or not. This is usually used for determining whether to force a stable ordering (like alphabetic ordering by name) if no ordering if explicitly specified.
    Default implementation returns false as JSON does NOT require stable ordering. Formats that require ordering include positional textual formats like CSV, and schema-based binary formats like Avro.
    
    Since:
    
    2.3
  - canHandleBinaryNatively
```
public boolean canHandleBinaryNatively()
```
    Introspection method that higher-level functionality may call to see whether underlying data format can read and write binary data natively; that is, embeded it as-is without using encodings such as Base64.
    Default implementation returns false as JSON does not support native access: all binary content must use Base64 encoding. Most binary formats (like Smile and Avro) support native binary content.
    
    Since:
    
    2.3
  - canUseCharArrays
```
public boolean canUseCharArrays()
```
    Introspection method that can be used by base factory to check whether access using char[] is something that actual parser implementations can take advantage of, over having to use Reader. Sub-types are expected to override definition; default implementation (suitable for JSON) alleges that optimization are possible; and thereby is likely to try to access String content by first copying it into recyclable intermediate buffer.
    
    Since:
    
    2.4
  - canParseAsync
```
public boolean canParseAsync()
```
    Introspection method that can be used to check whether this factory can create non-blocking parsers: parsers that do not use blocking I/O abstractions but instead use a NonBlockingInputFeeder.
    
    Since:
    
    2.9
  - getFormatReadFeatureType
```
public java.lang.Class<? extends FormatFeature> getFormatReadFeatureType()

    Since:
    
    2.6
  - getFormatWriteFeatureType
```
public java.lang.Class<? extends FormatFeature> getFormatWriteFeatureType()
```
    Method for accessing kind of FormatFeature that a parser JsonGenerator produced by this factory would accept, if any; null returned if none.
    
    Since:
    
    2.6
  - canUseSchema
```
public boolean canUseSchema(FormatSchema schema)
```
    Method that can be used to quickly check whether given schema is something that parsers and/or generators constructed by this factory could use. Note that this means possible use, at the level of data format (i.e. schema is for same data format as parsers and generators this factory constructs); individual schema instances may have further usage restrictions.
    
    Since:
    
    2.1
  - getFormatName
```
public java.lang.String getFormatName()
```
    Method that returns short textual id identifying format this factory supports.
    Note: sub-classes should override this method; default implementation will return null for all sub-classes

```
    Method for constructing JSON parser instance to parse contents of specified file.
    Encoding is auto-detected from contents according to JSON specification recommended mechanism. Json specification supports only UTF-8, UTF-16 and UTF-32 as valid encodings, so auto-detection implemented only for this charsets. For other charsets use createParser(java.io.Reader).
    Underlying input stream (needed for reading contents) will be owned (and managed, i.e. closed as need be) by the parser, since caller has no access to it.
    
    Parameters:
    
    f - File that contains JSON content to parse

                               JsonParseException
```
    Method for constructing JSON parser instance to parse contents of resource reference by given URL.
    Encoding is auto-detected from contents according to JSON specification recommended mechanism. Json specification supports only UTF-8, UTF-16 and UTF-32 as valid encodings, so auto-detection implemented only for this charsets. For other charsets use createParser(java.io.Reader).
    Underlying input stream (needed for reading contents) will be owned (and managed, i.e. closed as need be) by the parser, since caller has no access to it.
    
    Parameters:
    
    url - URL pointing to resource that contains JSON content to parse

```
    Method for constructing JSON parser instance to parse the contents accessed via specified input stream.
    The input stream will not be owned by the parser, it will still be managed (i.e. closed if end-of-stream is reacher, or parser close method called) if (and only if) JsonParser.Feature.AUTO_CLOSE_SOURCE is enabled.
    Note: no encoding argument is taken since it can always be auto-detected as suggested by JSON RFC. Json specification supports only UTF-8, UTF-16 and UTF-32 as valid encodings, so auto-detection implemented only for this charsets. For other charsets use createParser(java.io.Reader).

```
    Method for constructing parser for parsing the contents accessed via specified Reader.

                                               JsonParseException
```
    Deprecated. Since 2.2, use createParser(File) instead.
    
    Method for constructing JSON parser instance to parse contents of specified file.
    Encoding is auto-detected from contents according to JSON specification recommended mechanism. Json specification supports only UTF-8, UTF-16 and UTF-32 as valid encodings, so auto-detection implemented only for this charsets. For other charsets use createParser(java.io.Reader).
    Underlying input stream (needed for reading contents) will be owned (and managed, i.e. closed as need be) by the parser, since caller has no access to it.
    
    Parameters:
    
    f - File that contains JSON content to parse
    
    Throws:
    
    java.io.IOException
    
    JsonParseException

    Deprecated. Since 2.2, use createParser(URL) instead.
    
    Method for constructing JSON parser instance to parse contents of resource reference by given URL.
    Encoding is auto-detected from contents according to JSON specification recommended mechanism. Json specification supports only UTF-8, UTF-16 and UTF-32 as valid encodings, so auto-detection implemented only for this charsets. For other charsets use createParser(java.io.Reader).
    Underlying input stream (needed for reading contents) will be owned (and managed, i.e. closed as need be) by the parser, since caller has no access to it.
    
    Parameters:
    
    url - URL pointing to resource that contains JSON content to parse

```
    Deprecated. Since 2.2, use createParser(InputStream) instead.
    
    Method for constructing JSON parser instance to parse the contents accessed via specified input stream.
    The input stream will not be owned by the parser, it will still be managed (i.e. closed if end-of-stream is reacher, or parser close method called) if (and only if) JsonParser.Feature.AUTO_CLOSE_SOURCE is enabled.
    Note: no encoding argument is taken since it can always be auto-detected as suggested by JSON RFC. Json specification supports only UTF-8, UTF-16 and UTF-32 as valid encodings, so auto-detection implemented only for this charsets. For other charsets use createParser(java.io.Reader).
    
    Parameters:
    
    in - InputStream to use for reading JSON content to parse

                              throws java.io.IOException
```
    Method for constructing JSON generator for writing JSON content using specified output stream. Encoding to use must be specified, and needs to be one of available types (as per JSON specification).
    Underlying stream is NOT owned by the generator constructed, so that generator will NOT close the output stream when JsonGenerator.close() is called (unless auto-closing feature, JsonGenerator.Feature.AUTO_CLOSE_TARGET is enabled). Using application needs to close it explicitly if this is the case.
    Note: there are formats that use fixed encoding (like most binary data formats) and that ignore passed in encoding.
    
    Parameters:
    
    out - OutputStream to use for writing JSON content
