StringLinker

public StringLinker(CharSequence delimiter)

Constructs a StringJoiner with no characters in it, with no prefix or suffix, and a copy of the supplied delimiter. If no characters are added to the StringJoiner and methods accessing the value of it are invoked, it will not return a prefix or suffix (or properties thereof) in the result, unless setEmptyValue has first been called.

参数:

delimiter - the sequence of characters to be used between each element added to the StringJoiner value

抛出:

NullPointerException - if delimiter is null

StringLinker

public StringLinker(CharSequence delimiter,
                    CharSequence prefix,
                    CharSequence suffix)

Constructs a StringJoiner with no characters in it using copies of the supplied prefix, delimiter and suffix. If no characters are added to the StringJoiner and methods accessing the string value of it are invoked, it will return the prefix + suffix (or properties thereof) in the result, unless setEmptyValue has first been called.

参数:

delimiter - the sequence of characters to be used between each element added to the StringJoiner

prefix - the sequence of characters to be used at the beginning

suffix - the sequence of characters to be used at the end

抛出:

NullPointerException - if prefix, delimiter, or suffix is null

方法详细资料

of

public static StringLinker of()

of

public static StringLinker of(CharSequence delimiter)

of

public static StringLinker of(CharSequence delimiter,
                              CharSequence prefix,
                              CharSequence suffix)

wrapper

public StringLinker wrapper(CharSequence prefix,
                            CharSequence suffix)

setEmptyValue

public StringLinker setEmptyValue(CharSequence emptyValue)

Sets the sequence of characters to be used when determining the string representation of this StringJoiner and no elements have been added yet, that is, when it is empty. A copy of the emptyValue parameter is made for this purpose. Note that once an add method has been called, the StringJoiner is no longer considered empty, even if the element(s) added correspond to the empty String.

参数:

emptyValue - the characters to return as the value of an empty StringJoiner

返回:

this StringJoiner itself so the calls may be chained

抛出:

NullPointerException - when the emptyValue parameter is null

setNullElement

public StringLinker setNullElement(CharSequence defaultElementIfNull)

link

public StringLinker link(Object... newElements)

add

public StringLinker add(Object newElement)

add

public StringLinker add(CharSequence newElement,
                        int times)

add

public StringLinker add(byte[] newElement)

add

public StringLinker add(int[] newElement)

add

public StringLinker add(float[] newElement)

add

public StringLinker add(long[] newElement)

add

public StringLinker add(short[] newElement)

add

public StringLinker add(double[] newElement)

add

public StringLinker add(Object[] newElement)

merge

public StringLinker merge(StringLinker other)

Adds the contents of the given StringJoiner without prefix and suffix as the next element if it is non-empty. If the given StringJoiner is empty, the call has no effect.

A StringJoiner is empty if add() has never been called, and if merge() has never been called with a non-empty StringJoiner argument.

If the other StringJoiner is using a different delimiter, then elements from the other StringJoiner are concatenated with that delimiter and the result is appended to this StringJoiner as a single element.

参数:

other - The StringJoiner whose contents should be merged into this one

返回:

This StringJoiner

抛出:

NullPointerException - if the other StringJoiner is null

length

public int length()

Returns the length of the String representation of this StringJoiner. Note that if no add methods have been called, then the length of the String representation (either prefix + suffix or emptyValue) will be returned. The value should be equivalent to toString().length().

指定者:

length 在接口中 CharSequence

返回:

the length of the current value of StringJoiner

charAt

public char charAt(int index)

指定者:

charAt 在接口中 CharSequence

subSequence

public CharSequence subSequence(int start,
                                int end)

指定者:

subSequence 在接口中 CharSequence

toString

public String toString()

Returns the current value, consisting of the prefix, the values added so far separated by the delimiter, and the suffix, unless no elements have been added in which case, the prefix + suffix or the emptyValue characters are returned

指定者:

toString 在接口中 CharSequence

覆盖:

toString 在类中 Object

返回:

the string representation of this StringJoiner
