SpannedString

SpannedString

public SpannedString (CharSequence source)

For the backward compatibility reasons, this constructor copies all spans including NoCopySpan.

charAt

public char charAt (int i)

Returns the char value at the specified index. An index ranges from zero to length() - 1. The first char value of the sequence is at index zero, the next at index one, and so on, as for array indexing.

If the char value specified by the index is a surrogate, the surrogate value is returned.

equals

public boolean equals (Object o)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

getChars

public void getChars (int start, 
                int end, 
                char[] dest, 
                int off)

Exactly like String.getChars(): copy chars start through end - 1 from this CharSequence into dest beginning at offset destoff.

getSpanEnd

public int getSpanEnd (Object what)

Return the end of the range of text to which the specified markup object is attached, or -1 if the object is not attached.

getSpanFlags

public int getSpanFlags (Object what)

Return the flags that were specified when Spannable#setSpan was used to attach the specified markup object, or 0 if the specified object has not been attached.

getSpanStart

public int getSpanStart (Object what)

Return the beginning of the range of text to which the specified markup object is attached, or -1 if the object is not attached.

getSpans

public T[] getSpans (int queryStart, 
                int queryEnd, 
                Class<T> kind)

Return an array of the markup objects attached to the specified slice of this CharSequence and whose type is the specified type or a subclass of it. Specify Object.class for the type if you want all the objects regardless of type.

hashCode

public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

length

public int length ()

Returns the length of this character sequence. The length is the number of 16-bit chars in the sequence.

nextSpanTransition

public int nextSpanTransition (int start, 
                int limit, 
                Class<T> kind)

Return the first offset greater than start where a markup object of class type begins or ends, or limit if there are no starts or ends greater than start but less than limit. Specify null or Object.class for the type if you want every transition regardless of type.

subSequence

public CharSequence subSequence (int start, 
                int end)

Returns a CharSequence that is a subsequence of this sequence. The subsequence starts with the char value at the specified index and ends with the char value at index end - 1. The length (in chars) of the returned sequence is end - start, so if start == end then an empty sequence is returned.

toString

public String toString ()

Returns a string representation of the object.

valueOf

public static SpannedString valueOf (CharSequence source)
