抛出:

IOException

endArray

public void endArray()
              throws IOException

从类复制的说明: JsonReader

Consumes the next token from the JSON stream and asserts that it is the end of the current array.

覆盖:

endArray 在类中 JsonReader

抛出:

IOException

beginObject

public void beginObject()
                 throws IOException

从类复制的说明: JsonReader

Consumes the next token from the JSON stream and asserts that it is the beginning of a new object.

覆盖:

beginObject 在类中 JsonReader

抛出:

IOException

endObject

public void endObject()
               throws IOException

从类复制的说明: JsonReader

Consumes the next token from the JSON stream and asserts that it is the end of the current object.

覆盖:

endObject 在类中 JsonReader

抛出:

IOException

hasNext

public boolean hasNext()
                throws IOException

从类复制的说明: JsonReader

Returns true if the current array or object has another element.

覆盖:

hasNext 在类中 JsonReader

抛出:

IOException

peek

public JsonToken peek()
               throws IOException

从类复制的说明: JsonReader

Returns the type of the next token without consuming it.

覆盖:

peek 在类中 JsonReader

抛出:

IOException

nextName

public String nextName()
                throws IOException

从类复制的说明: JsonReader

Returns the next token, a property name, and consumes it.

覆盖:

nextName 在类中 JsonReader

抛出:

IOException - if the next token in the stream is not a property name.

nextString

public String nextString()
                  throws IOException

从类复制的说明: JsonReader

Returns the string value of the next token, consuming it. If the next token is a number, this method will return its string form.

覆盖:

nextString 在类中 JsonReader

抛出:

IOException

nextBoolean

public boolean nextBoolean()
                    throws IOException

从类复制的说明: JsonReader

Returns the boolean value of the next token, consuming it.

覆盖:

抛出:

IOException

nextDouble

public double nextDouble()
                  throws IOException

从类复制的说明: JsonReader

Returns the double value of the next token, consuming it. If the next token is a string, this method will attempt to parse it as a double using Double.parseDouble(String).

覆盖:

nextDouble 在类中 JsonReader

抛出:

IOException

nextLong

public long nextLong()
              throws IOException

从类复制的说明: JsonReader

Returns the long value of the next token, consuming it. If the next token is a string, this method will attempt to parse it as a long. If the next token's numeric value cannot be exactly represented by a Java long, this method throws.

覆盖:

nextLong 在类中 JsonReader

抛出:

抛出:

IOException

skipValue

public void skipValue()
               throws IOException

从类复制的说明: JsonReader

Skips the next value recursively. If it is an object or array, all nested elements are skipped. This method is intended for use when the JSON token stream contains unrecognized or unhandled values.

覆盖:
