构造器详细资料

TextNode

public TextNode(String v)

方法详细资料

valueOf

public static TextNode valueOf(String v)

Factory method that should be used to construct instances. For some common cases, can reuse canonical instances: currently this is the case for empty Strings, in future possible for others as well. If null is passed, will return null.

返回:

Resulting TextNode object, if v is NOT null; null if it is.

asToken

public JsonToken asToken()

从类复制的说明: BaseJsonNode

Method that can be used for efficient type detection when using stream abstraction for traversing nodes. Will return the first JsonToken that equivalent stream event would produce (for most nodes there is just one token but for structured/container types multiple)

指定者:

asToken 在类中 ValueNode

isTextual

public boolean isTextual()

Yes indeed it is textual

覆盖:

isTextual 在类中 JsonNode

getTextValue

public String getTextValue()

从类复制的说明: JsonNode

Method to use for accessing String values. Does NOT do any conversions for non-String value nodes; for non-String values (ones for which JsonNode.isTextual() returns false) null will be returned. For String values, null is never returned (but empty Strings may be)

覆盖:

getTextValue 在类中 JsonNode

返回:

Textual value this node contains, iff it is a textual json node (comes from Json String value entry)

getBinaryValue

public byte[] getBinaryValue(Base64Variant b64variant)
                      throws IOException

Method for accessing textual contents assuming they were base64 encoded; if so, they are decoded and resulting binary data is returned.

抛出:

IOException

getBinaryValue

public byte[] getBinaryValue()
                      throws IOException

从类复制的说明: JsonNode

Method to use for accessing binary content of binary nodes (nodes for which JsonNode.isBinary() returns true); or for Text Nodes (ones for which JsonNode.getTextValue() returns non-null value), to read decoded base64 data. For other types of nodes, returns null.

覆盖:

getBinaryValue 在类中 JsonNode

返回:

Binary data this node contains, iff it is a binary node; null otherwise

抛出:

IOException

asText

public String asText()

从类复制的说明: JsonNode

Method that will return valid String representation of the container value, if the node is a value node (method JsonNode.isValueNode() returns true), otherwise empty String.

指定者:

asText 在类中 JsonNode

asBoolean

public boolean asBoolean(boolean defaultValue)

从类复制的说明: JsonNode

Method that will try to convert value of this node to a Java boolean. JSON booleans map naturally; integer numbers other than 0 map to true, and 0 maps to false and Strings 'true' and 'false' map to corresponding values.

If representation can not be converted to a boolean value (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.

覆盖:

asBoolean 在类中 JsonNode

asInt

public int asInt(int defaultValue)

从类复制的说明: JsonNode

Method that will try to convert value of this node to a Java int. Numbers are coerced using default Java rules; booleans convert to 0 (false) and 1 (true), and Strings are parsed using default Java language integer parsing rules.

If representation can not be converted to an int (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.

覆盖:

asInt 在类中 JsonNode

asLong

public long asLong(long defaultValue)

从类复制的说明: JsonNode

Method that will try to convert value of this node to a Java long. Numbers are coerced using default Java rules; booleans convert to 0 (false) and 1 (true), and Strings are parsed using default Java language integer parsing rules.

If representation can not be converted to an long (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.

覆盖:

asLong 在类中 JsonNode

asDouble

public double asDouble(double defaultValue)

从类复制的说明: JsonNode

Method that will try to convert value of this node to a Java double. Numbers are coerced using default Java rules; booleans convert to 0.0 (false) and 1.0 (true), and Strings are parsed using default Java language integer parsing rules.

If representation can not be converted to an int (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.

覆盖:

asDouble 在类中 JsonNode

serialize

public final void serialize(JsonGenerator jg,
             SerializerProvider provider)
                     throws IOException,
                            JsonProcessingException

从类复制的说明: BaseJsonNode

Method called to serialize node instances using given generator.

指定者:

serialize 在接口中 JsonSerializable

指定者:

serialize 在类中 BaseJsonNode

抛出:

IOException

JsonProcessingException

equals

public boolean equals(Object o)

从类复制的说明: JsonNode

Equality for node objects is defined as full (deep) value equality. This means that it is possible to compare complete JSON trees for equality by comparing equality of root nodes.

Note: marked as abstract to ensure all implementation classes define it properly and not rely on definition from Object.

指定者:

equals 在类中 JsonNode

hashCode

public int hashCode()

覆盖:

hashCode 在类中 Object

toString

public String toString()

Different from other values, Strings need quoting

覆盖:

toString 在类中 ValueNode

appendQuoted

protected static void appendQuoted(StringBuilder sb,
                String content)

_reportInvalidBase64

protected void _reportInvalidBase64(Base64Variant b64variant,
                        char ch,
                        int bindex)
                             throws JsonParseException

抛出:

JsonParseException

_reportInvalidBase64

protected void _reportInvalidBase64(Base64Variant b64variant,

                        String msg)
                             throws JsonParseException

参数:

bindex - Relative index within base64 character unit; between 0 and 3 (as unit has exactly 4 characters)

抛出:

JsonParseException

_reportBase64EOF

protected void _reportBase64EOF()
                         throws JsonParseException

抛出:

JsonParseException
