Public Methods

public boolean equals ( Object obj)

Added in API level 1

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 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.

Parameters
obj the object to compare this instance with.
Returns
  • true if the specified object is equal to this Object ; false otherwise.

public static NumericShaper getContextualShaper (int ranges)

Added in API level 1

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 static NumericShaper getContextualShaper (int ranges, int defaultContext)

Added in API level 1

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 int getRanges ()

Added in API level 1

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)

Added in API level 1

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 ()

Added in API level 1

Returns an integer hash code for this object. By contract, any two objects for which equals(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.

Returns
  • this object's hash code.

public boolean isContextual ()

Added in API level 1

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, int context)

Added in API level 1

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 void shape (char[] text, int start, int count)

Added in API level 1

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 String toString ()

Added in API level 1

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.

Returns
  • a printable representation of this object.
