public boolean allOptions(int options)

Implements com.vladsch.flexmark.util.sequence.BasedOptionsHolder.allOptions.

Doc from com.vladsch.flexmark.util.sequence.BasedOptionsHolder.allOptions.

Options test for options for this sequence

default reports true for global default options (if any) , variation available on BasedSequenceWithOptions

Parameters
options:int

option flags

Returns:boolean

true if all option flags passed are set for this sequence

public boolean anyOptions(int options)

Implements com.vladsch.flexmark.util.sequence.BasedOptionsHolder.anyOptions.

Doc from com.vladsch.flexmark.util.sequence.BasedOptionsHolder.anyOptions.

Options test for options for this sequence

default reports true for global default options (if any) , variation available on BasedSequenceWithOptions

Parameters
options:int

option flags

Returns:boolean

true if any option flags passed are set for this sequence

Annotations
@Override
charAtback to summary
public char charAt(int index)

Implements java.lang.CharSequence.charAt.

Doc from java.lang.CharSequence.charAt.

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.

Parameters
index:int

the index of the char value to be returned

Returns:char

the specified char value

Annotations
@Override
charsback to summary
public IntStream chars()

Overrides default java.lang.CharSequence.chars.

Doc from java.lang.CharSequence.chars.

Returns a stream of int zero-extending the char values from this sequence. Any char which maps to a surrogate code point is passed through uninterpreted.

The stream binds to this sequence when the terminal stream operation commences (specifically, for mutable sequences the spliterator for the stream is late-binding). If the sequence is modified during that operation then the result is undefined.

Returns:IntStream

an IntStream of char values from this sequence

Annotations
@Override
codePointsback to summary
public IntStream codePoints()

Overrides default java.lang.CharSequence.codePoints.

Doc from java.lang.CharSequence.codePoints.

Returns a stream of code point values from this sequence. Any surrogate pairs encountered in the sequence are combined as if by Character.toCodePoint and the result is passed to the stream. Any other code units, including ordinary BMP characters, unpaired surrogates, and undefined code units, are zero-extended to int values which are then passed to the stream.

The stream binds to this sequence when the terminal stream operation commences (specifically, for mutable sequences the spliterator for the stream is late-binding). If the sequence is modified during that operation then the result is undefined.

Returns:IntStream

an IntStream of Unicode code points from this sequence

Annotations
@Override
equalsback to summary
public boolean equals(Object o)

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

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.

Parameters
o:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

public <T> T getOption(DataKeyBase<T> dataKey)

Implements com.vladsch.flexmark.util.sequence.BasedOptionsHolder.getOption.

Options holder, default has none, only available on BasedSequenceWithOptions

Returns:@Nullable DataHolder

@Override
hashCodeback to summary
public int hashCode()

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.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.
Returns:int

a hash code value for this object

lengthback to summary
public int length()

Implements java.lang.CharSequence.length.

Doc from java.lang.CharSequence.length.

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

Returns:int

subSequenceback to summary
public CharSequence subSequence(int start, int end)

Implements java.lang.CharSequence.subSequence.

Doc from java.lang.CharSequence.subSequence.

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.

Parameters
start:int

the start index, inclusive

end:int

the end index, exclusive

Returns:CharSequence

the specified subsequence

Doc from java.lang.CharSequence.toString.

Returns a string containing the characters in this sequence in the same order as this sequence. The length of the string will be the length of this sequence.

Returns:String

a string consisting of exactly this sequence of characters
