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
