DelimitedLineTokenizer
public DelimitedLineTokenizer()
Create a new instance of theDelimitedLineTokenizer
class for the common case where the delimiter is acomma
.
DelimitedLineTokenizer
public DelimitedLineTokenizer(java.lang.String delimiter)
Create a new instance of theDelimitedLineTokenizer
class.- 参数:
delimiter
- the desired delimiter. This is required
方法详细资料
setDelimiter
public void setDelimiter(java.lang.String delimiter)
Setter for the delimiter character.- 参数:
delimiter
- the String used as a delimiter
setIncludedFields
public void setIncludedFields(int... includedFields)
The fields to include in the output by position (starting at 0). By default all fields are included, but this property can be set to pick out only a few fields from a larger set. Note that if field names are provided, their number must match the number of included fields.- 参数:
includedFields
- the included fields to set
setQuoteCharacter
public void setQuoteCharacter(char quoteCharacter)
Public setter for the quoteCharacter. The quote character can be used to extend a field across line endings or to enclose a String which contains the delimiter. Inside a quoted token the quote character can be used to escape itself, thus "a""b""c" is tokenized to a"b"c.- 参数:
quoteCharacter
- the quoteCharacter to set- 另请参阅:
DEFAULT_QUOTE_CHARACTER
doTokenize
protected java.util.List<java.lang.String> doTokenize(java.lang.String line)
Yields the tokens resulting from the splitting of the suppliedline
.- 指定者:
doTokenize
在类中AbstractLineTokenizer
- 参数:
line
- the line to be tokenized- 返回:
- the resulting tokens
isQuoteCharacter
protected boolean isQuoteCharacter(char c)
Is the supplied character a quote character?- 参数:
c
- the character to be checked- 返回:
true
if the supplied character is an quote character- 另请参阅:
setQuoteCharacter(char)
afterPropertiesSet
public void afterPropertiesSet() throws java.lang.Exception
- 指定者:
afterPropertiesSet
在接口中org.springframework.beans.factory.InitializingBean
- 抛出:
java.lang.Exception
