方法详细资料

getCurrentName

public String getCurrentName()
                      throws IOException,
                             JsonParseException

Method that can be called to get the name associated with the current event.

指定者:

getCurrentName 在类中 ParserMinimalBase

抛出:

IOException

JsonParseException

overrideCurrentName

public void overrideCurrentName(String name)

从类复制的说明: JacksonParser

Method that can be used to change what is considered to be the current (field) name. May be needed to support non-JSON data formats or unusual binding conventions; not needed for typical processing.

Note that use of this method should only be done as sort of last resort, as it is a work-around for regular operation.

指定者:

overrideCurrentName 在类中 ParserMinimalBase

参数:

name - Name to use as the current name; may be null.

close

public void close()
           throws IOException

从类复制的说明: JacksonParser

Closes the parser so that no further iteration or data access can be made; will also close the underlying input source if parser either owns the input source, or feature JacksonParser.Feature.AUTO_CLOSE_SOURCE is enabled. Whether parser owns the input source depends on factory method that was used to construct instance (so check JsonFactory for details, but the general idea is that if caller passes in closable resource (such as InputStream or Reader) parser does NOT own the source; but if it passes a reference (such as File or URL and creates stream or reader it does own them.

指定者:

close 在接口中 Closeable

指定者:

close 在接口中 AutoCloseable

指定者:

close 在类中 ParserMinimalBase

抛出:

IOException

isClosed

public boolean isClosed()

从类复制的说明: JacksonParser

Method that can be called to determine whether this parser is closed or not. If it is closed, no new tokens can be retrieved by calling JacksonParser.nextToken() (and the underlying stream may be closed). Closing may be due to an explicit call to JacksonParser.close() or because parser has encountered end of input.

指定者:

isClosed 在类中 ParserMinimalBase

getParsingContext

public JsonReadContext getParsingContext()

从类复制的说明: JacksonParser

Method that can be used to access current parsing context reader is in. There are 3 different types: root, array and object contexts, with slightly different available information. Contexts are hierarchically nested, and can be used for example for figuring out part of the input document that correspond to specific array or object (for highlighting purposes, or error reporting). Contexts can also be used for simple xpath-like matching of input, if so desired.

指定者:

getParsingContext 在类中 ParserMinimalBase

getTokenLocation

public JsonLocation getTokenLocation()

Method that return the starting location of the current token; that is, position of the first character from input that starts the current token.

指定者:

getTokenLocation 在类中 JacksonParser

getCurrentLocation

public JsonLocation getCurrentLocation()

Method that returns location of the last processed character; usually for error reporting purposes

指定者:

getCurrentLocation 在类中 JacksonParser

hasTextCharacters

public boolean hasTextCharacters()

从类复制的说明: JacksonParser

Method that can be used to determine whether calling of JacksonParser.getTextCharacters() would be the most efficient way to access textual content for the event parser currently points to.

Default implementation simply returns false since only actual implementation class has knowledge of its internal buffering state. Implementations are strongly encouraged to properly override this method, to allow efficient copying of content by other code.

指定者:

hasTextCharacters 在类中 ParserMinimalBase

返回:

True if parser currently has character array that can be efficiently returned via JacksonParser.getTextCharacters(); false means that it may or may not exist

getTokenCharacterOffset

public long getTokenCharacterOffset()

getTokenLineNr

public int getTokenLineNr()

getTokenColumnNr

public int getTokenColumnNr()

_getByteArrayBuilder

public ByteArrayBuilder _getByteArrayBuilder()

getNumberValue

                      throws IOException,
                             JsonParseException

从类复制的说明: JacksonParser

Generic number value accessor method that will work for all kinds of numeric values. It will return the optimal (simplest/smallest possible) wrapper object that can express the numeric value just parsed.

指定者:

getNumberValue 在类中 JacksonParser

抛出:

IOException

JsonParseException

getNumberType

public JacksonParser.NumberType getNumberType()
                                       throws IOException,
                                              JsonParseException

从类复制的说明: JacksonParser

If current token is of type JsonToken.VALUE_NUMBER_INT or JsonToken.VALUE_NUMBER_FLOAT, returns one of JacksonParser.NumberType constants; otherwise returns null.

指定者:

getNumberType 在类中 JacksonParser

抛出:

IOException

JsonParseException

getIntValue

public int getIntValue()
                throws IOException,
                       JsonParseException

从类复制的说明: JacksonParser

Numeric accessor that can be called when the current token is of type JsonToken.VALUE_NUMBER_INT and it can be expressed as a value of Java int primitive type. It can also be called for JsonToken.VALUE_NUMBER_FLOAT; if so, it is equivalent to calling JacksonParser.getDoubleValue() and then casting; except for possible overflow/underflow exception.

Note: if the resulting integer value falls outside range of Java int, a JsonParseException may be thrown to indicate numeric overflow/underflow.

指定者:

getIntValue 在类中 JacksonParser

抛出:

IOException

JsonParseException

getLongValue

public long getLongValue()
                  throws IOException,
                         JsonParseException

从类复制的说明: JacksonParser

Numeric accessor that can be called when the current token is of type JsonToken.VALUE_NUMBER_INT and it can be expressed as a Java long primitive type. It can also be called for JsonToken.VALUE_NUMBER_FLOAT; if so, it is equivalent to calling JacksonParser.getDoubleValue() and then casting to int; except for possible overflow/underflow exception.

Note: if the token is an integer, but its value falls outside of range of Java long, a JsonParseException may be thrown to indicate numeric overflow/underflow.
