text

public String text()
            throws IOException

Throws:

IOException

utf8Bytes

public org.apache.lucene.util.BytesRef utf8Bytes()
                                          throws IOException

Description copied from interface: XContentParser

Returns a BytesRef holding UTF-8 bytes. This method should be used to read text only binary content should be read through XContentParser.binaryValue()

Throws:

IOException

objectText

public Object objectText()
                  throws IOException

Throws:

IOException

objectBytes

public Object objectBytes()
                   throws IOException

Throws:

IOException

hasTextCharacters

public boolean hasTextCharacters()

Description copied from interface: XContentParser

Method that can be used to determine whether calling of textCharacters() 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. This method shouldn't be used to check if the token contains text or not.

textCharacters

Throws:

IOException

binaryValue

public byte[] binaryValue()
                   throws IOException

Description copied from interface: XContentParser

Reads a plain binary value that was written via one of the following methods:

• XContentBuilder.field(String, org.apache.lucene.util.BytesRef)
• XContentBuilder.field(String, org.elasticsearch.common.bytes.BytesReference)
• XContentBuilder.field(String, byte[], int, int)}
• XContentBuilder.field(String, byte[])}

as well as via their XContentBuilderString variants of the separated value methods. Note: Do not use this method to read values written with:

• XContentBuilder.utf8Field(XContentBuilderString, org.apache.lucene.util.BytesRef)
• XContentBuilder.utf8Field(String, org.apache.lucene.util.BytesRef)

these methods write UTF-8 encoded strings and must be read through:

• XContentParser.utf8Bytes()
• XContentParser.utf8BytesOrNull()}
• XContentParser.text() ()}
• XContentParser.textOrNull() ()}
• XContentParser.textCharacters() ()}}

Throws:

IOException

getTokenLocation

public XContentLocation getTokenLocation()

Description copied from interface: XContentParser

Used for error reporting to highlight where syntax errors occur in content being parsed.

Returns:

last token's location or null if cannot be determined

close

public void close()

isClosed

public boolean isClosed()

Specified by:

isClosed in interface XContentParser

Specified by:
