Constructor Detail

Codepoint

public Codepoint(byte[] bytes)

Create a Codepoint from a byte array using the default encoding (UTF-8)

Codepoint

public Codepoint(byte[] bytes,
                 String encoding)
          throws UnsupportedEncodingException

Create a Codepoint from a byte array with the specified charset encoding. Length must equal 1

Throws:

UnsupportedEncodingException

Codepoint

public Codepoint(CharSequence value)

Create a Codepoint from a CharSequence. Length must equal 1

Codepoint

public Codepoint(char value)

Create a codepoint from a single char

Codepoint

public Codepoint(char high,
                 char low)

Create a codepoint from a surrogate pair

Codepoint

public Codepoint(Codepoint codepoint)

Create a codepoint as a copy of another codepoint

Codepoint

public Codepoint(int value)

Create a codepoint from a specific integer value

Method Detail

getValue

public int getValue()

The codepoint value

isSupplementary

public boolean isSupplementary()

True if this codepoint is supplementary

isLowSurrogate

public boolean isLowSurrogate()

True if this codepoint is a low surrogate

isHighSurrogate

public boolean isHighSurrogate()

True if this codepoint is a high surrogate

getHighSurrogate

public char getHighSurrogate()

Get the high surrogate of this Codepoint

getLowSurrogate

public char getLowSurrogate()

Get the low surrogate of this Codepoint

isBidi

public boolean isBidi()

True if this Codepoint is a bidi control char

isDigit

public boolean isDigit()

isAlpha

public boolean isAlpha()

isAlphaDigit

public boolean isAlphaDigit()

compareTo

public int compareTo(Codepoint o)

Specified by:

compareTo in interface Comparable<Codepoint>

toString

public String toString()

Overrides:

toString in class Object

toChars

public char[] toChars()

getCharCount

public int getCharCount()

Get the number of chars necessary to represent this codepoint. Returns 2 if this is a supplementary codepoint

toBytes

public byte[] toBytes()

toBytes

public byte[] toBytes(String encoding)
               throws UnsupportedEncodingException

Throws:

UnsupportedEncodingException

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

getPlane

public int getPlane()

Plane 0 (0000–FFFF): Basic Multilingual Plane (BMP). This is the plane containing most of the character assignments so far. A primary objective for the BMP is to support the unification of prior character sets as well as characters for writing systems in current use. Plane 1 (10000–1FFFF): Supplementary Multilingual Plane (SMP). Plane 2 (20000–2FFFF): Supplementary Ideographic Plane (SIP) Planes 3 to 13 (30000–DFFFF) are unassigned Plane 14 (E0000–EFFFF): Supplementary Special-purpose Plane (SSP) Plane 15 (F0000–FFFFF) reserved for the Private Use Area (PUA) Plane 16 (100000–10FFFF), reserved for the Private Use Area (PUA)

clone

public Codepoint clone()

Overrides:

clone in class Object

next

public Codepoint next()

Get the next codepoint

previous

public Codepoint previous()

Get the previous codepoint
