Public Methods

public boolean equals (Object obj)

Compares this NumericShaper object with the specified Object.

Parameters
obj the Object to be compared.
Returns
  • true, if this NumericShaper object is equal to the specified Object, false otherwise.

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.

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.

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.

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.

public int hashCode ()

Returns a hash code of this NumericShaper.

Returns
  • a hash code of this NumericShaper.

public boolean isContextual ()

Checks if this NumericShaper is contextual (supporting multiple script ranges) or not.

Returns
  • true, if this NumericShaper is contextual, false otherwise.

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.

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.

public String toString ()

Returns a string representation of this NumericShaper.

Returns
  • the string representation of this NumericShaper.
