| Package | Description | 
|---|---|
| com.fasterxml.jackson.core | Main public API classes of the core streaming JSON
 processor: most importantly  JsonFactoryused for constructing
 JSON parser (JsonParser)
 and generator
 (JsonGenerator)
 instances. | 
| com.fasterxml.jackson.core.base | Base classes used by concrete Parser and Generator implementations;
 contain functionality that is not specific to JSON or input
 abstraction (byte vs char). | 
| com.fasterxml.jackson.core.exc | Package for some of  JsonProcessingExceptionsubtypes contained by streaming API. | 
| com.fasterxml.jackson.core.filter | |
| com.fasterxml.jackson.core.io | |
| com.fasterxml.jackson.core.json | JSON-specific parser and generator implementation classes that
 Jackson defines and uses. | 
| Modifier and Type | Class and Description | 
|---|---|
| class  | JsonGenerationExceptionException type for exceptions during JSON writing, such as trying
 to output  content in wrong context (non-matching end-array or end-object,
 for example). | 
| class  | JsonParseExceptionException type for parsing problems, used when non-well-formed content
 (content that does not conform to JSON syntax as per specification)
 is encountered. | 
| Modifier and Type | Method and Description | 
|---|---|
| abstract <T extends TreeNode> | TreeCodec. readTree(JsonParser p) | 
| abstract <T> T | ObjectCodec. treeToValue(TreeNode n,
           Class<T> valueType)Convenience method for converting given JSON tree into instance of specified
 value type. | 
| abstract void | TreeCodec. writeTree(JsonGenerator g,
         TreeNode tree) | 
| Modifier and Type | Method and Description | 
|---|---|
| protected char | ParserBase. _handleUnrecognizedCharacterEscape(char ch) | 
| Modifier and Type | Class and Description | 
|---|---|
| class  | InputCoercionExceptionException type for read-side problems that are not direct decoding ("parsing")
 problems (those would be reported as  JsonParseExceptions),
 but rather result from failed attempts to convert specific Java value out of valid
 but incompatible input value. | 
| class  | StreamReadExceptionIntermediate base class for all read-side streaming processing problems, including
 parsing and input value coercion problems. | 
| class  | StreamWriteExceptionIntermediate base class for all read-side streaming processing problems, including
 parsing and input value coercion problems. | 
| Modifier and Type | Method and Description | 
|---|---|
| TokenFilter | TokenFilterContext. setFieldName(String name) | 
| Modifier and Type | Class and Description | 
|---|---|
| class  | JsonEOFExceptionSpecialized  JsonParseExceptionthat is thrown when end-of-input
 is reached unexpectedly, either within token being decoded, or during
 skipping of intervening white-space that is not between root-level
 tokens (that is, is within JSON Object or JSON Array construct). | 
| Modifier and Type | Method and Description | 
|---|---|
| void | JsonReadContext. setCurrentName(String name) | 
| int | JsonWriteContext. writeFieldName(String name)Method that writer is to call before it writes a name of Object property. |
