Syntax

public sealed class UnescapedCharSequence : ICharSequence

Constructors

UnescapedCharSequence(ICharSequence)

Create a non-escaped J2N.Text.ICharSequence

Declaration

public UnescapedCharSequence(ICharSequence text)

Parameters

Type	Name	Description
ICharSequence	text

UnescapedCharSequence(char[], bool[], int, int)

Create a escaped J2N.Text.ICharSequence

Declaration

public UnescapedCharSequence(char[] chars, bool[] wasEscaped, int offset, int length)

Parameters

Type	Name	Description
char[]	chars
bool[]	wasEscaped
int	offset
int	length

UnescapedCharSequence(string)

Create a non-escaped string

Declaration

public UnescapedCharSequence(string text)

Parameters

Type	Name	Description
string	text

UnescapedCharSequence(StringBuilder)

Create a non-escaped StringBuilder

Declaration

public UnescapedCharSequence(StringBuilder text)

Parameters

Type	Name	Description
StringBuilder	text

Properties

this[int]

Gets the character at the specified index, with the first character having index zero.

Declaration

public char this[int index] { get; }

Parameters

Type	Name	Description
int	index	The index of the character to return.

Property Value

Type	Description
char	The requested character.

Exceptions

Type	Condition
IndexOutOfRangeException	If index < 0 or index is greater than the length of this sequence.
InvalidOperationException	If the underlying value of this sequence is null.

Length

Gets the number of characters in this sequence.

Declaration

public int Length { get; }

Property Value

Type	Description
int

Methods

Subsequence(int, int)

Retrieves a sub-sequence from this instance. The sub-sequence starts at a specified character position and has a specified length.

IMPORTANT: This method has .NET semantics, that is, the second parameter is a length, not an exclusive end index as it would be in Java. To translate from Java to .NET, callers must account for this by subtracting (end - start) for the length.

Declaration

public ICharSequence Subsequence(int startIndex, int length)

Parameters

Type	Name	Description
int	startIndex	The start index of the sub-sequence. It is inclusive, that is, the index of the first character that is included in the sub-sequence.
int	length	The number of characters to return in the sub-sequence.

Returns

Type	Description
ICharSequence

Exceptions

Type	Condition
ArgumentOutOfRangeException	startIndex plus length indicates a position not within this instance. -or- startIndex or length is less than zero.

ToLower(ICharSequence, CultureInfo)

J2N.Text.ICharSequence with escaped chars information.

Declaration

public static ICharSequence ToLower(ICharSequence text, CultureInfo locale)

Parameters

Type	Name	Description
ICharSequence	text
CultureInfo	locale

Returns

Type	Description
ICharSequence

ToString()

Declaration

Returns

Type	Description

Overrides
