    • Method Detail

      • hashCode

        public int hashCode()
        Description copied from class: Object
        Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

        Note that hash values must not change over time unless information used in equals comparisons also changes.

        See Writing a correct hashCode method if you intend implementing your own hashCode method.

        Overrides:
        hashCode in class Object
        Returns:
        this object's hash code.
        See Also:
        Object.equals(java.lang.Object)

      • equals

        public boolean equals​(Object obj)
        Description copied from class: Object
        Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

        The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

        The general contract for the equals and Object.hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

        Overrides:
        equals in class Object
        Parameters:
        obj - the object to compare this instance with.
        Returns:
        true if the specified object is equal to this Object; false otherwise.
        See Also:
        Object.hashCode()

      • toString

        public String toString()
        Description copied from class: Object
        Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression: 
           getClass().getName() + '@' + Integer.toHexString(hashCode())

        See Writing a useful toString method if you intend implementing your own toString method.

        Overrides:
        toString in class Object
        Returns:
        a printable representation of this object.

      • getContextualShaper

        public static NumericShaper getContextualShaper​(int ranges,
                                                int defaultContext)
        Gets the NumericShaper for the specified unicode ranges and default unicode range. The defaultContext parameter is used as the starting context (which indicates the language/script being used). The OR logical operation should be used for multiple ranges: NumericShaper.DEVANAGARI | NumericShaper.BENGALI. The NumericShaper returned by this method is contextual in that it supports multiple character ranges, depending on the context.
        Parameters:
        ranges - the unicode ranges.
        defaultContext - the default, starting context.
        Returns:
        the NumericShaper for the specified ranges.

      • getContextualShaper

        public static NumericShaper getContextualShaper​(int ranges)
        Gets the NumericShaper for the specified unicode ranges. The OR logical operation should be used for multiple ranges: NumericShaper.DEVANAGARI | NumericShaper.BENGALI. The NumericShaper returned by this method is contextual in that it supports multiple character ranges, depending on the context.
        Parameters:
        ranges - the unicode ranges.
        Returns:
        the NumericShaper for the specified ranges.

      • getRanges

        public int getRanges()
        Gets the masks for all of the ranges supported by this NumericShaper, packed into an int value using the logical OR logical operation for multiple ranges: NumericShaper.DEVANAGARI | NumericShaper.BENGALI.
        Returns:
        all ranges of this NumericShaper.

      • getShaper

        public static NumericShaper getShaper​(int singleRange)
        Gets a NumericShaper for the specified unicode range. The NumericShaper supports only a single range and hence is not contextual.
        Parameters:
        singleRange - the specified unicode single range.
        Returns:
        the NumericShaper for the specified unicode range.

      • isContextual

        public boolean isContextual()
        Checks if this NumericShaper is contextual (supporting multiple script ranges) or not.
        Returns:
        true, if this NumericShaper is contextual, false otherwise.

      • shape

        public void shape​(char[] text,
                  int start,
                  int count,
                  int context)
        Transforms the encoding of the text, starting from the character at index start and transforming count characters, using the specified context.
        Parameters:
        text - the text to be shaped.
        start - the start offset of the text.
        count - the number of characters to be shaped.
        context - the context to be used for shaping.

      • shape

        public void shape​(char[] text,
                  int start,
                  int count)
        Transforms the encoding of the text, starting from the character at index start and transforming count characters.
        Parameters:
        text - the text to be shaped.
        start - the start offset of the text.
        count - the number of characters to be shaped.
