append

expect open override fun append(value: Char): StringBuilder

Appends the specified character value to this Appendable and returns this instance.

Parameters

value

the character to append.

expect open override fun append(value: CharSequence?): StringBuilder

Appends the specified character sequence value to this Appendable and returns this instance.

Parameters

value

the character sequence to append. If value is null, then the four characters "null" are appended to this Appendable.

expect open override fun append(value: CharSequence?, startIndex: Int, endIndex: Int): StringBuilder

Appends a subsequence of the specified character sequence value to this Appendable and returns this instance.

Parameters

value

the character sequence from which a subsequence is appended. If value is null, then characters are appended as if value contained the four characters "null".

startIndex

the beginning (inclusive) of the subsequence to append.

endIndex

the end (exclusive) of the subsequence to append.

Throws

kotlin.IndexOutOfBoundsException

or IllegalArgumentException when startIndex or endIndex is out of range of the value character sequence indices or when startIndex > endIndex.

expect fun append(value: Any?): StringBuilder

Appends the string representation of the specified object value to this string builder and returns this instance.

The overall effect is exactly as if the value were converted to a string by the value.toString() method, and then that string was appended to this string builder.

expect fun append(value: Boolean): StringBuilder

Appends the string representation of the specified boolean value to this string builder and returns this instance.

The overall effect is exactly as if the value were converted to a string by the value.toString() method, and then that string was appended to this string builder.

Since Kotlin

1.3

expect fun append(value: CharArray): StringBuilder

Appends characters in the specified character array value to this string builder and returns this instance.

Characters are appended in order, starting at the index 0.

Since Kotlin

1.4

expect fun append(value: String?): StringBuilder

Appends the specified string value to this string builder and returns this instance.

If value is null, then the four characters "null" are appended.

Since Kotlin

1.3

actual open override fun append(value: Char): StringBuilder

Appends the specified character value to this Appendable and returns this instance.

Parameters

value

the character to append.

actual open override fun append(value: CharSequence?): StringBuilder

Appends the specified character sequence value to this Appendable and returns this instance.

Parameters

value

the character sequence to append. If value is null, then the four characters "null" are appended to this Appendable.

actual open override fun append(value: CharSequence?, startIndex: Int, endIndex: Int): StringBuilder

Appends a subsequence of the specified character sequence value to this Appendable and returns this instance.

Parameters

value

the character sequence from which a subsequence is appended. If value is null, then characters are appended as if value contained the four characters "null".

startIndex

the beginning (inclusive) of the subsequence to append.

endIndex

the end (exclusive) of the subsequence to append.

Throws

kotlin.IndexOutOfBoundsException

or IllegalArgumentException when startIndex or endIndex is out of range of the value character sequence indices or when startIndex > endIndex.
